pitavastatin and Dyslipidemias

A subpopulation of statin users such as subjects with chronic kidney disease (CKD), Human Immune virus (HIV), acute coronary syndrome (ACS), revascularization, metabolic syndrome, and/or diabetes may particularly benefit from pitavastatin pharmacotherapy.. The current systematic review aimed systematically to evaluate the effect of pitavastatin on primary cardiac events in subjects receiving pitavastatin in comparison to the other four statin members.. We conducted a systematic review on phases III and IV of randomized controlled trials (RCT-s, 11 trials) for subjects with primary cardiac events who received pitavastatin. Subjects diagnosed with any type of dyslipidemia (population 4804) and received pitavastatin (interventions) versus comparator (comparison) with the primary efficacy endpoint of minimization of LDL-C and non- HDL-C, had an increase in HDL-C and/or reduction in major adverse cardiac events (MACE, cardiovascular death, myocardial infarction (fatal/nonfatal), and stroke (fatal/nonfatal) and/or their composite (outcomes). The secondary safety endpoint was the development of any adverse effects.. In the included trials (11), participants (4804) were randomized for pitavastatin or its comparators such as atorvastatin, pravastatin, rosuvastatin, simvastatin and followed up for 12 to 52 weeks. In terms of the primary outcome (reduction in LDL-C), pitavastatin 4 mg was superior to pravastatin 40 mg in three trials, while the 2 mg pitavastatin was comparable to atorvastatin 10 mg in four trials and simvastatin 20 and 40 mg in two 2 trials. However, rosuvastatin 2.5 mg was superior to pitavastatin 2 mg in two trials. Pitavastatin increased HDL-C and reduced non-HDL-C in eleven trials. Regarding the safety profile, pitavastatin has proved to be tolerated and safe.. The FDA-approved indications for pitavastatin included primary dyslipidemia and mixed dyslipidemia as a supplementary therapy to dietary changes to lower total cholesterol, LDL-C, apolipoprotein B (Apo B), triglycerides (TG), and enhance HDL-C. Pitavastatin might be suitable for subjects with diabetes, ACS (reduced revascularization), metabolic syndrome, CKD, HIV, and subjects with low levels of HDL-C. We highly recommend rational individualization for the selection of statin.

Atorvastatin is the most common drug used in therapy for cardiovascular diseases. The most common adverse side effects associated with statins are myopathy and hypertransaminasemia. Here, we report a rare case of gamma glutamyl transpeptidase (GGT) elevation induced by atorvastatin.. A 47-year-old male was admitted to our hospital with dyslipidemia, he had been taking pitavastatin 2 mg/day for 2 months. The levels of total cholesterol (265.28 mg/dL) and low-density lipoprotein-cholesterol (LDL) (179.15 mg/dL) were also high.. Blood lipid test showed mixed dyslipidemia.. Atorvastatin 10 mg/day was given to the patient.. The patient came back to our hospital for blood tests after 4 weeks. Although no symptoms were detectable, the patient's GGT level was markedly elevated (up to 6-fold over normal level) with less marked increases in alkaline phosphatase (ALP) and alanine aminotransferase (ALT). The serum GGT level returned to normal within 6 weeks of cessation of atorvastatin.. This is a case of GGT elevation without hyperbilirubinemia, hypertransaminasemiam, or serum creatine phosphokinase (CPK) abnormalities despite an atorvastatin regimen. This case highlights GGT elevation caused by atorvastatin, a rare but serious condition. Clinicians should be aware of these possible adverse effects and monitor liver function tests in patients on statin therapy.

Dyslipidemia is commonly associated with endothelial dysfunction and increased cardiovascular risk. Pitavastatin has been shown to reduce total and low-density lipoprotein cholesterol, to increase high-density lipoprotein (HDL)-cholesterol and improve HDL function. Furthermore, several trials explored its effects on flow-mediated dilation (FMD), as an index of endothelial function. The authors evaluated the effect of pitavastatin therapy on FMD.. The authors performed a systematic review and meta-analysis of all clinical trials exploring the impact of pitavastatin on FMD. The search included PubMed-Medline, Scopus, ISI Web of Knowledge and Google Scholar databases. Quantitative data synthesis was performed using a random-effects model, with weighted mean difference (WMD) and 95% confidence interval (CI) as summary statistics.. Six eligible studies comprising 7 treatment arms were selected for this meta-analysis. Overall, WMD was significant for the effect of pitavastatin on FMD (2.45%, 95% CI: 1.31, 3.60, p < 0.001) and the effect size was robust in the leave-one-out sensitivity analysis.. This meta-analysis of all available clinical trials revealed a significant increase of FMD induced by pitavastatin.

The aim of this study is to compare the efficacy and safety of pitavastatin and atorvastatin using data from randomized-controlled trial pooled together by means of a meta-analysis and decide which is better.. PubMed, CENTRAL, Web of Knowledge, and ClinicalTrials.gov website were searched for randomized-controlled trials published until October 2016. Eligible studies comparing pitavastatin with atorvastatin head to head and reporting the outcome of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), glycated hemoglobin, and intravascular ultrasound evaluation were enrolled. Heterogeneity was assessed by using the I statistic, and the extracted data were estimated by fixed-effects model.. Eleven trials including a total number of 1733 participants were identified. Compared with atorvastatin, changes in the mean differences of LDL-C and HDL-C were 2.51 [95% confidence interval (CI): 1.17-3.86; I=48%; P=0.0003] and 2.17 (95% CI: 1.42-2.91; I=40%; P<0.00001), respectively, for pitavastatin. The changes in the mean differences of glycated hemoglobin was -0.15 (95% CI: -1.44-1.15; I=0%; P=0.83) for pitavastatin compared with atorvastatin. For plaque volume, lumen volume, and external elastic membrane, the changes are -0.93 (95% CI: -3.04-1.19; I=50%; P=0.39), 0.17 (95% CI: -2.91-3.26; I=0%; P=0.91), and -0.43 (95% CI: -1.96-1.11; I=4%; P=0.58), respectively, for pitavastatin versus atorvastatin.. In this study, pitavastatin seems to be less effective in reducing LDL-C and elevating HDL-C level compared with atorvastatin. Moreover, there is no significant difference in changes of glycated hemoglobin and intravascular ultrasound evaluation between pitavastatin and atorvastatin.

Low high density lipoprotein cholesterol (HDL-C) levels represent an independent risk factor for cardiovascular disease; in addition to the reduced HDL-C levels commonly observed in patients at cardiovascular risk, the presence of dysfunctional HDL, i.e. HDL with reduced atheroprotective properties, has been reported. Despite the established inverse correlation between HDL-C levels and cardiovascular risk, several clinical trials with HDL-C-increasing drugs (such as niacin, CETP inhibitors or fibrate) failed to demonstrate that a significant rise in HDL-C levels translate into a cardiovascular benefit. Statins, that are the most used lipid-lowering drugs, can also increase HDL-C levels, although this effect is highly variable among studies and statins; the most recent developed statin, pitavastatin, beside its role as LDL-C-lowering agent, increases HDL-C levels at a significantly higher extent and progressively upon treatment; such increase was observed also when patients where shifted from another statin to pitavastatin. The stratification by baseline HDL-C levels revealed that only pitavastatin significantly increased HDL-C levels in patients with baseline HDL-C ≤45 mg/dl, while no changes were observed in patients with higher baseline HDL-C levels. In the last years the hypothesis that functional properties of HDL may be more relevant than HDL-C levels has risen from several observations. The treatment with pitavastatin not only increased HDL-C levels, but also increased the phospholipid content of HDL, increased the HDL efflux capacity and their anti-oxidant properties. These observations suggest that, besides its high LDL-C-lowering effect, pitavastatin also exhibits a significantly higher ability to increase HDL-C levels and may also positively affect the quality and functionality of HDL particles.

Statins represent the elective lipid-lowering strategy in hyperlipidemic and high cardiovascular-risk patients. Despite excellent safety and tolerability, reversible muscle-related and dose-dependent adverse events may decrease a patient's compliance. Large meta-analyses, post-hoc and genetic studies showed that statins might increase the risk of new-onset diabetes (NOD), particularly in insulin-resistant, obese, old patients. Race, gender, concomitant medication, dose and treatment duration may also contribute to this effect. Based on this evidence, to warn against the possibility of statin-induced NOD or worsening glycemic control in patients with already established diabetes, FDA and EMA changed the labels of all the available statins in the USA and Europe. Recent meta-analyses and retrospective studies demonstrated that statins' diabetogenicity is a dose-related class effect, but the mechanism(s) is not understood. Among statins, only pravastatin and pitavastatin do not deteriorate glycemic parameters in patients with and without type 2 diabetes mellitus. Interestingly, available data, obtained in small-scale, retrospective or single-center clinical studies, document that pitavastatin, while ameliorating lipid profile, seems protective against NOD. Beyond differences in pharmacokinetics between pitavastatin and the other statins (higher oral bioavailability, lower hepatic uptake), its consistent increases in plasma adiponectin documented in clinical studies may be causally connected with its effect on glucose metabolism. Adiponectin is a protein with antiatherosclerotic, anti-inflammatory and antidiabetogenic properties exerted on liver, skeletal muscle, adipose tissue and pancreatic beta cells. Further studies are required to confirm this unique property of pitavastatin and to understand the mechanism(s) leading to this effect.

With the practice-shifting changes made with the most recent guidelines for treating blood cholesterol, more older patients may be prescribed statin therapy. Therefore, it is imperative that practitioners have not only a working knowledge of information related to statins, but more specifically to their efficacy and safety in elderly populations. Pitavastatin is the most recent statin to receive regulatory approval. It is indicated for the treatment of primary hyperlipidemia or mixed dyslipidemia as an adjunctive therapy to diet. The overall body of evidence for the efficacy and safety of pitavastatin in elderly patients is small. The available data suggest that the ability of pitavastatin to lower low-density lipoprotein cholesterol in elderly patients is at least similar, and may be greater than that seen in comparatively younger cohorts. Taken together, the limited available data suggest that pitavastatin is effective at improving lipid parameters in elderly patients with a similar safety profile to other agents in the class. Until data become available distinguishing pitavastatin from the other available options, its ultimate role in the hyperlipidemia treatment armamentarium remains unclear.

Whether adverse effect of statins on glycaemic indices is common to all statins remains controversial and as yet data for pitavastatin are limited. We sought to assess the effects of pitavastatin on glycaemia and new-onset diabetes (NOD) in non-diabetic individuals using data from RCT pooled together by means of a meta-analysis.. We searched Medline, Cochrane, Embase and clinical trials registries websites until November-2014 for ≥12-week follow-up placebo or statin-controlled RCT of pitavastatin that included participants without diabetes and reported on fasting blood glucose (FBG), HbA1c or NOD. We additionally sought studies by consulting with Kowa Ph. Ltd. The association of pitavastatin with the outcomes were estimated by random-effects meta-analyses. Heterogeneity was assessed by the I(2) statistic and sensitivity and subgroup analyses, and publication bias with funnel plots and Egger and Harbord Tests.. 15 studies (approx. 1600 person-years) were included. No significant differences associated with pitavastatin (vs. control) were observed for FBG (MD -0.01 mg/dL [95%CI -0.77, 0.74], I(2) = 0%), HbA1c (MD -0.03% [95%CI -0.11, 0.05], I(2) = 43%) or NOD (RR 0.70 [95%CI 0.30, 1.61]; RD 0.0 [95%CI -0.004, 0.003]; I(2) = 0%). Sensitivity and subgroup analyses (including type of control [placebo or other statin], pitavastatin dose or follow-up] did not yield significant results. Potential publication bias may occur for NOD.. In the present meta-analysis pitavastatin did not adversely affect glucose metabolism or diabetes development compared with placebo or other statins.

Pitavastatin is the latest statin to be approved and has shown beneficial effects on plasma lipid profiles. The aim of the present meta-analysis was to assess both the efficacy and safety of pitavastatin versus simvastatin, one of the most commonly used statins.. A search of the MEDLINE, EMBASE, OVID and Cochrane Central Register of Controlled Trials (CENTRAL) databases was undertaken. Clinical trials evaluating the efficacy and safety of simvastatin versus pitavastatin, published up to February 2014, were identified. Trials were included if they (1) were randomized controlled trials (RCTs) of at least 12 weeks' duration; (2) included patients with primary hypercholesterolaemia or mixed dyslipidaemia; (3) studied outcomes included low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C); and (4) were published in the English language. A fixed-effects model was used for data analysis if no significant heterogeneity was present; otherwise a random-effects model was used. Efficacy is reflected by the mean difference in the percentage change of plasma lipid profiles. Treatment-emergent adverse events (TEAEs) are presented as risk ratio (RR).. A total of 1,468 patients were included in the meta-analysis. The results indicated similar efficacy of pitavastatin (versus simvastatin) in lowering LDL-C. Pitavastatin also had similar effects to simvastatin on other major aspects of plasma lipids, including TC, TG and HDL-C. Somewhat in contrast to common belief (based on distinct metabolism by P450 subtypes), the two statins did not differ in the incidence of TEAE.. In clinical trials, pitavastatin was comparable to simvastatin in both efficacy and safety profile. Large-scale, high-quality observational studies are required to determine whether the advantage of pitavastatin in metabolism profiles could be translated into noticeable benefits.

The term cardiometabolic disease encompasses a range of lifestyle-related conditions, including Metabolic syndrome (MetS) and type 2 diabetes (T2D), that are characterized by different combinations of cardiovascular (CV) risk factors, including dyslipidemia, abdominal obesity, hypertension, hyperglycemia/insulin resistance, and vascular inflammation. These risk factors individually and interdependently increase the risk of CV and cerebrovascular events, and represent one of the biggest health challenges worldwide today. CV diseases account for almost 50% of all deaths in Europe and around 30% of all deaths worldwide. Furthermore, the risk of CV death is increased twofold to fourfold in people with T2D. Whilst the clinical management of CV disease has improved in Western Europe, the pandemic of obesity and T2D reduces the impact of these gains. This, together with the growing, aging population, means the number of CV deaths is predicted to increase from 17.1 million worldwide in 2004 to 23.6 million in 2030. The recommended treatment for MetS is lifestyle change followed by treatment for the individual risk factors. Numerous studies have shown that lowering low-density lipoprotein-cholesterol (LDL-C) levels using statins can significantly reduce CV risk in people with and without T2D or MetS. However, the risk of major vascular events in those attaining the maximum levels of LDL-C-reduction is only reduced by around one-third, which leaves substantial residual risk. Recent studies suggest that low high-density lipoprotein-cholesterol (HDL-C) (<1 .0 mmol/l; 40 mg/dl) and high triglyceride levels (≥1.7 mmol/l; 150 mg/dl) are independent risk factors for CV disease and that the relationship between HDL-C and CV risk persists even when on-treatment LDL-C levels are low (<1.7 mmol/l; 70 mg/dl). European guidelines highlight the importance of reducing residual risk by targeting these risk factors in addition to LDL-C. This is particularly important in patients with T2D and MetS because obesity and high levels of glycated hemoglobin are directly related to low levels of HDL-C and high triglyceride. Although most statins have a similar low-density lipoprotein-lowering efficacy, differences in chemical structure and pharmacokinetic profile can lead to variations in pleiotropic effects (for example, high-density lipoprotein-elevating efficacy), adverse event profiles, and drug-drug interactions. The choice of statin should therefore depend on the needs of the indivi

Statins effectively lower low-density lipoprotein-cholesterol (LDL-C) and reduce cardiovascular risk in people with dyslipidemia and cardiometabolic diseases such as Metabolic syndrome (MetS) or type 2 diabetes (T2D). In addition to elevated levels of LDL-C, people with these conditions often have other lipid-related risk factors, such as high levels of triglycerides, low levels of high-density lipoprotein-cholesterol (HDL-C), and a preponderance of highly atherogenic, small, dense low-density lipoprotein particles. The optimal management of dyslipidemia in people with MetS or T2D should therefore address each of these risk factors in addition to LDL-C. Although statins typically have similar effects on LDL-C levels, differences in chemical structure and pharmacokinetic profile can lead to variations in pleiotropic effects, adverse event profiles and drug-drug interactions. The choice of statin should therefore depend on the characteristics and needs of the individual patient. Compared with other statins, pitavastatin has distinct pharmacological features that translate into a broad range of actions on both apolipoprotein-B-containing and apolipoprotein-A-containing lipoproteins. Studies show that pitavastatin 1 to 4 mg is well tolerated and significantly improves LDL-C and triglyceride levels to a similar or greater degree than comparable doses of atorvastatin, simvastatin or pravastatin, irrespective of diabetic status. Moreover, whereas most statins show inconsistent effects on HDL-C levels, pitavastatin-treated patients routinely experience clinically significant elevations in HDL-C that are maintained and even increased over the long term. In addition to increasing high-density lipoprotein quantity, pitavastatin appears to improve high-density lipoprotein function and to slow the progression of atherosclerotic plaques by modifying high-density lipoprotein-related inflammation and oxidation, both of which are common in patients with MetS and T2D. When choosing a statin, it is important to note that patients with MetS have an increased risk of developing T2D and that some statins can exacerbate this risk via adverse effects on glucose regulation. Unlike many statins, pitavastatin appears to have a neutral and even beneficial effect on glucose regulation, making it a useful treatment option in this high-risk group of patients. Together with pitavastatin's beneficial effects on the cardiometabolic lipid profile and its low potential for drug-drug interac

Type 2 diabetes (T2D) is a strong, independent risk factor for cardiovascular (CV) and cerebrovascular outcomes. Meta-analysis of five randomised clinical trials (n = 33,040) showed that, although intensive versus standard glycaemic control significantly reduced CV events in people with T2D, the reduction was less than that achieved with lipid-lowering or antihypertensive treatment. Furthermore, fasting plasma glucose (FPG) concentrations were a modest predictor for CV risk in people without T2D. Thus, although effective glycaemic control is important for the prevention/management of T2D, other risk factors must be addressed to effectively reduce CV risk. Reducing low-density lipoprotein-cholesterol levels using statins significantly reduces CV risk in people with and without T2D. Although statins are generally safe and well tolerated, conflicting data exist regarding the diabetogenic effects of some statins. Based on recent clinical trial data, the US Food and Drug Administration have changed the labelling of all statins to include 'an effect of statins on incident diabetes and increases in haemoglobin A1c and/or FPG'. However, the literature suggests that the beneficial effects of most statins on CV risk continue to outweigh their diabetogenic risks and that statins should remain as first-line therapy for the majority of people with dyslipidaemia and metabolic syndrome or T2D. Mechanisms explaining the potentially higher incidence of T2D with statin therapy have not been confirmed. However, independent predictors for statin-associated T2D appear to include elevated levels of baseline FPG, BMI, blood pressure and fasting triglycerides. Moreover, although some statins (for example, atorvastatin) are associated with increased haemoglobin A1c levels in patients receiving intensive but not moderate therapy, other statins (for example, pitavastatin) have demonstrated neutral or favourable effects on glucose control in patients with and without T2D or metabolic syndrome. The potential diabetogenic effects of statins may therefore differ between drugs. In conclusion, conflicting data exist regarding the diabetogenic effects of statins. Further studies are required to understand whether all statins have the same effect and whether some patient groups are at higher risk than others. Meanwhile, results suggest that the net CV benefit favours the use of statin therapy in patients with dyslipidaemia, irrespective of T2D risk.

Pitavastatin is the last marketed statin. Different studies have shown that pitavastatin is more potent than pravastatin and simvastatin in reducing LDL-cholesterol levels, and equivalent to atorvastatin and rosuvastatin. Moreover, pitavastatin provides a significant and sustained increase of HDL-cholesterol levels. Remarkably, as pitavastatin is minimally metabolized by CYP, the risk of interactions with other drugs is low. Additionally, pitavastatin does not interfere with glucose metabolism in diabetics and non-diabetics, and exerts a beneficial effect in patients with renal dysfunction. However, although available information may suggest that pitavastatin can improve cardiovascular prognosis, data coming from specifically designed clinical trials are still warranted. The aim of this review was to update the available evidence about efficacy and safety of pitavastatin, and to analyze the place of pitavastatin in the current armamentarium for the treatment of patients with hypercholesterolemia.

Pitavastatin is the latest available statin. It has been shown to be effective in the treatment of dyslipidaemia. This meta-analysis was aimed at evaluating the effects of pitavastatin on lipid profiles in patients with dyslipidaemia compared with atorvastatin.. Clinical trials were identified through electronic searches (MEDLINE, CINAHL, EBM review, and the Cochrane Library) up to January 2011 and historical searches of relevant articles. Studies were included in the meta-analysis if they were (i) randomized controlled trials that evaluated pitavastatin at the recommended dose vs. atorvastatin in patients with dyslipidaemia, (ii) lasting at least 6weeks, (iii) reporting total cholesterol (TC), LDL-C, HDL-C or triglyceride (TG) levels and (iv) published in English. Treatment effect was estimated with the mean difference in the per cent changes in lipid profiles from baseline to final assessment between pitavastatin and atorvastatin.. Seven trials involving 1529 patients were included. Pitavastatin reduced LDL-C level as effectively as atorvastatin (mean difference 0.97%, 95% CI -0.48% to 2.42%). The reductions in TC and TG levels were also comparable between the two drugs. The mean differences were 1.22% (95% CI -0.55% to 2.99%) and 2.3% (95% CI -1.06% to 5.65%), respectively. However, HDL-C levels increased significantly more with pitavastatin than with atorvastatin (mean difference 1.78%, 95% CI 0.20-3.36%, P=0.03).. Pitavastatin was as effective as atorvastatin in lowering LDL-C, TC and TG levels. Pitavastatin was marginally superior to atorvastatin in increasing HDL-C levels.

3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) are the most widely prescribed therapeutic class of drugs worldwide, with established clinical benefits both in terms of improving serum lipid profiles and reducing cardiovascular events and mortality. Although statins have a favorable risk-to-benefit ratio, they have the potential to cause adverse events which can result in muscular inflammation (myositis), muscle breakdown (rhabdomyolysis) and, ultimately, kidney failure. While the incidence of rhabdomyolysis is approximately 3.4 cases per 100,000 person-years with standard-dose statin therapy, the risk of developing the condition increases substantially at higher therapeutic doses. This effect may be exacerbated by prescribing statins in combination with certain other medications because drug � drug interactions increase statin exposure by interacting with enzymes that would normally be involved in their metabolism and clearance. Co-administration of drugs that inhibit the cytochrome P450 (CYP) enzymes responsible for metabolizing statins, or that interact with the organic anion-transporting polypeptides (OATPs) responsible for statin uptake into hepatocytes, substantially increases the risk of developing myotoxicity. Such effects vary among statins according to their metabolic profile. For example, pitavastatin, a novel statin approved for the treatment of hypercholesterolemia and combined (mixed) dyslipidemia, is not catabolized by CYP3A4, unlike other lipophilic statins, and may be less dependent on the OATP1B1 transporter for its uptake into hepatocytes before clearance. Such differences in drug � drug interaction profiles among available statins offer the possibility of reducing the risk of myotoxicity among high-risk patients.

Pitavastatin (Livazo®, Livalo®), an inhibitor of HMG-CoA reductase (statin), is indicated for the reduction of elevated total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels, in adult patients with primary hypercholesterolaemia and mixed dyslipidaemia, when response to diet and other non-pharmacological measures is inadequate. Pitavastatin has a favourable pharmacological profile following oral administration, including its long half-life (up to 12 hours), selective uptake into hepatocytes and minimal metabolism by cytochrome P450 (CYP) enzymes. This latter property decreases the likelihood of drug-drug interactions with agents that are metabolized by, inhibit or induce CYP enzymes. Pitavastatin improved the lipid profile (including LDL-C, TC and high-density lipoprotein cholesterol levels) in patients with hypercholesterolaemia and mixed dyslipidaemia, according to large, pivotal phase III studies of up to 60 weeks' duration. In these trials, pitavastatin for 12 weeks was noninferior to simvastatin and atorvastatin in terms of the improvement from baseline in LDL-C levels. In similarly designed trials, pitavastatin improved lipid profiles and was noninferior to simvastatin in patients with high cardiovascular risk and demonstrated significantly greater LDL-C reduction than pravastatin in elderly patients. Furthermore, in patients with type 2 diabetes mellitus, although noninferiority criteria for the comparison with atorvastatin were not met in terms of the improvement from baseline in LDL-C levels, pitavastatin was associated with some improvements in the lipid profile. Pitavastatin also demonstrated substantial lipid-modifying effects in exclusively Asian populations in well designed clinical trials. Pitavastatin was generally well tolerated in clinical trials of up to 60 weeks' duration, with a tolerability profile generally similar to that of atorvastatin and simvastatin. Therefore, pitavastatin appears to be an attractive alternative for the treatment of patients with primary hyperlipidaemia or mixed dyslipidaemia who have not responded adequately to diet and other non-pharmacological measures, and may present a useful treatment option in patients requiring polypharmacy, such as those at high risk of cardiovascular disease. Further studies evaluating the effects of pitavastatin on clinical endpoints, such as cardiovascular morbidity and mortality, are required to confirm the longer-term benefits of pitavastatin.

Pitavastatin calcium is a new addition to the class of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors ("statins") approved for use in the United States for the treatment of primary hyperlipidemia and mixed dyslipidemia.. The purpose of this review was to evaluate the literature related to the medicinal chemistry, pharmacology, pharmacokinetic properties, clinical efficacy, and tolerability of pitavastatin in the treatment of hyperlipidemia.. A search of MEDLINE, EMBASE, and the Journal Archive for English-language literature was conducted for articles published through January 2011 using the following search terms: itavastatin, Livalo, nisvastatin, NK 104, and pitavastatin. Articles were reviewed if they pertained to the clinical efficacy, pharmacology, pharmacokinetic properties, or tolerability of pitavastatin. Clinical trials were systematically included in the analysis of clinical efficacy if they used a randomized design to study the effects of the drug on hyperlipidemia, hypercholesterolemia, or heart disease. Trials were excluded if they did not signify the statin used, did not pertain to clinical efficacy, or enrolled <20 patients.. A total of 16 studies were identified and reviewed for clinical efficacy. Based on findings from pharmacokinetic studies, pitavastatin may be given at any time of the day, with or without food. The drug had a mean plasma elimination t(1/2) of 12 hours, is expected to be associated with minimal drug-drug interactions because it is not metabolized by the cytochrome P450 3A4 isozyme, and is primarily excreted unchanged in the bile with little renal elimination. Clinical trials described the effects of pitavastatin on cholesterol, high-sensitivity C-reactive protein (hs-CRP), and progression of atherosclerosis. Pitavastatin at doses of 1 to 4 mg/d was reported to be associated with reductions in LDL-C of 38% to 44% and in triglycerides of 14% to 22%, and with increases in HDL-C of 5% to 8% (all, P < 0.05). Overall, the effect of pitavastatin on cholesterol was comparable to those of atorvastatin and simvastatin at low to intermediate doses. Studies on the effects of pitavastatin on cardiovascular outcomes were lacking. The adverse-events (AE) profile of pitavastatin compared favorably with those of other available statins. AEs included gastrointestinal symptoms (0.7%-2.2%), myopathies (0.3%-1.1%), and elevated hepatic enzyme concentrations (0.0%-8.8%).. Based on the findings from previously published clinical trials, pitavastatin is an effective lipid lowering agent and is another therapeutic option of currently available statins.

Although clinical trials provide useful information on drug safety and efficacy, results do not always reflect those observed in the real world. The Japanese long-term prospective post-marketing surveillance LIVALO Effectiveness and Safety (LIVES) Study was designed to assess the efficacy and safety of pitavastatin in clinical practice in ~20,000 patients. After 104 weeks, pitavastatin was associated with significant reductions in low-density lipoprotein-cholesterol (LDL-C) (29.1%) that largely occurred within 4 weeks of treatment initiation. In patients with abnormal triglyceride (TG) and high-density lipoprotein-cholesterol (HDL-C) levels at baseline, pitavastatin reduced TG and increased HDL-C by 22.7% and 19.9%, respectively. Overall, 88.2% of the primary prevention low-risk patients attained their Japan Atherosclerosis Society LDL-C target, compared with 82.7% of intermediate-risk patients, 66.5% of high-risk patients and 50.3% of secondary prevention patients. Only 10.4% of pitavastatin-treated patients experienced adverse events (AEs), of which approximately 84% were mild and around 1% was severe. Increases in blood creatine phosphokinase (2.7%), alanine aminotransferase (1.8%), myalgia (1.1%), aspartate aminotransferase (1.5%) and gamma-glutamyltransferase (1.0%) were the most common AEs and only 7.4% of patients discontinued pitavastatin due to AEs. Regression analysis demonstrated that age was not a significant factor for the incidence of any AE or myopathy-associated events. A subanalysis of initial LIVES data focussing on the effects of pitavastatin on HDL-C levels showed that HDL-C was elevated by 5.9% in all patients and by 24.6% in those with low (

Atherogenic dyslipidemia is characterised by high levels of triglycerides, low levels of high-density lipoprotein-cholesterol (HDL-C), and moderate to marked elevations in low-density lipoprotein-cholesterol (LDL-C) concentrations; such dyslipidemia is further characterised by high apolipoprotein B (apoB): apolipoprotein A1 (apoA1) ratios. Numerous clinical trials have demonstrated that statins are effective in lowering LDL-C and reducing cardiovascular (CV) risk in people with dyslipidemia. However, the most effective treatments should target all of the key atherogenic features, rather than LDL-C alone. Pitavastatin is a new member of the statin class whose distinct pharmacological features translate into a broad spectrum of action on both apoB-containing and apoA1-containing lipoprotein components of the atherogenic lipid profile. The efficacy and safety of this statin has been demonstrated by a large clinical development programme conducted both in Japanese and Caucasian populations. Phase III and IV studies in a wide range of patients with primary hypercholesterolemia or combined dyslipidemia showed that 12 weeks' treatment with pitavastatin l-4 mg was well tolerated, significantly improved lipid profiles (including LDL-C, TG, and HDL-C levels) and increased the EAS-/NCEP ATP Ill-recommended LDL-C target attainment rate to a similar or greater degree as comparable doses of atorvastatin, simvastatin, or pravastatin. Results were similar across all patient groups and were generally sustained after 52 weeks of treatment. However, whereas the effects of atorvastatin and simvastatin on HDL-C levels remained constant over the long term, pitavastatin-treated patients experienced progressive and maintained elevations in HDL-C, ultimately increasing by up to 14.3% vs. initial baseline. In this context, it is significant that the in vitro studies of Yamashita et al. [J Atheroscler Thromb 2010;17:436-51] have shown pitavastatin to be distinguished by its potent stimulation of apoA1 production in hepatocyte-like cells. These findings suggest that pitavastatin may be highly efficacious in raising levels of lipid-poor apoA1 particles, which are known to be highly active in ABCA1-mediated cellular cholesterol efflux, an observation which is pertinent to the excessive accumulation of cholesterol in macrophage foam cells of the atherosclerotic plaque. Indeed, the intravascular remodelling and maturation of lipid-poor apoA1 particles is known to drive flux of apoA1, ch

Pitavastatin is a new, synthetic member of the statin class of lipid-lowering drugs. Compared with other available statins, it has a unique cyclopropyl group on its base structure that is believed to increase 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibition by a factor of five and to significantly increase the transcription and activity of LDL receptors. Pitavastatin is primarily metabolized via glucuronidation and is not a substrate for the cytochrome P450 3A4 enzyme, thus avoiding the potential for cytochrome P450-mediated drug-drug interactions. Clinical trials have shown that pitavastatin is comparable to atorvastatin and simvastatin in improving lipid measures, and more potent than pravastatin. Pitavastatin is effective in reducing triglycerides and increasing HDL-cholesterol, so it will be particularly beneficial in treating patients with mixed dyslipidemia. Its safety and adverse event profile is similar to that of other available statins, and it has an established history of use in Asia indicating tolerability and safety for treatment lasting up to 7 years.

Pitavastatin was first developed in Japan and is expanding the regions in which it is clinically available. A considerable number of clinical studies have been conducted and published to date on the usefulness of pitavastatin for patients with primary hypercholesterolemia or combined dyslipidemia. Pitavastatin demonstrates potent low-density lipoprotein cholesterol reduction at low doses of 1-4 mg/day. It also affects the regression of coronary plaques, as observed in intravascular ultrasound-guided percutaneous coronary intervention studies. Moreover, the persistent, long-term high-density lipoprotein cholesterol elevation observed in the populations treated with pitavastatin is worthy of further attention. The reported improvements in lipid profiles are consistent among the studies conducted in Japan, Korea, Thailand, and Europe. In light of accumulating clinical experience worldwide, pitavastatin is now expected to establish its position for preventing and treating cardiovascular disease.

The pitavastatin Phase III and IV studies assessed the efficacy and safety of standard dose pitavastatin vs. comparable doses of alternative statins in a broad range of patients with hypercholesterolaemia. Phase III studies conducted in Europe included five 12-week, randomised, double-blind trials evaluating the non-inferiority of pitavastatin 1-4mg vs. atorvastatin 10-20mg, simvastatin 20-40 mg and/or pravastatin 10-40mg in patients with primary hypercholesterolaemia and combined dyslipidaemia, including patients with high cardiovascular risk, type II diabetes, and age ≥65 years. The primary endpoint was the adjusted mean percent change from baseline in low-density lipoprotein-cholesterol (LDL-C); secondary endpoints included changes from baseline in lipid and lipoprotein profiles, LDL-C-target attainment rates and safety parameters. For each study, treatment was continued in open-label, long-term extension studies. Phase IV Japanese studies included CHIBA - a 12-week, open-label active control, non-inferiority investigator-led trial comparing the efficacy and safety of pitavastatin 2mg and atorvastatin 10 mg in patients with hypercholesterolaemia; PIAT - a 52-week open-label, investigator-led, randomised, parallel-group study comparing the efficacy and tolerability of pitavastatin 2mg and atorvastatin 10 mg in patients with hypercholesterolaemia and glucose intolerance; and LIVES - a 2-year prospective post-marketing surveillance of pitavastatin in 20,279 patients with hypercholesterolaemia. The primary endpoint for the first two studies was the percent change from baseline in non-high-density lipoprotein-C (non-HDL-C) and HDL-C, respectively; secondary endpoints included % changes from baseline in other lipid/lipoprotein parameters, safety and tolerability. Overall, Phase III and IV studies demonstrate that pitavastatin 1-4mg is well tolerated, improves atherogenic lipid profile and increases LDL-C target attainment rates with a similar or greater efficacy to comparable doses of atorvastatin, simvastatin and pravastatin in most patient groups. In each of these studies, improvements in lipid profile were sustained or improved during the long term suggesting benefits for continued treatment with pitavastatin.

Managing dyslipidaemia is central to the management of cardiovascular disease. Most statins can reduce the 5-year incidence of major vascular events by 20%. In Europe, however, up to 53% of statin-treated patients fail to attain their low-density lipoprotein-cholesterol (LDL-C) target and residual risk remains high, even when targets are reached. Reasons for this include under-treatment due to insufficient starting doses/failure to uptitrate; poor persistence with therapy due to adverse events (AEs) or drug-drug interactions (DDIs); and failure to treat non-LDL-C risk factors, such as high triglycerides (TGs) and low high-density lipoprotein-C (HDL-C). Phase III and IV studies demonstrate that pitavastatin 1-4 mg has a similar or greater lipid-lowering efficacy to atorvastatin 10-20 mg, simvastatin 20-40 mg and pravastatin 10-40 mg, and is well-tolerated with a low incidence of adverse events (AEs). The SmPC recommends a usual starting dose of 1 mg, with dose-escalation if required. However, since the lower doses (1-2 mg) bring the majority of people with hypercholesterolaemia or combined dyslipidaemia to LDL-C target, the need for pitavastatin uptitration and the risk of under-treatment is low. In addition to reducing LDL-C, pitavastatin has a sustained beneficial effect on other atherogenic lipids, including TGs and HDL-C. Recent studies reveal that pitavastatin reduces coronary atheroma plaque volume as efficiently as atorvastatin and can improve the composition of coronary plaques, effects that are likely to reduce the risk of CV endpoints in patients with acute coronary syndrome. Moreover, pitavastatin has a number of pleiotropic effects that can reduce inflammation and lipid oxidation, improve endothelial function, reduce the metabolic changes associated with adiposity, and improve glucose metabolism and renal function. Compared to other statins, pitavastatin has a unique metabolic profile that could reduce the risk of DDIs, thereby providing a clear benefit in patients receiving polypharmacy. Overall, pitavastatin is a well tolerated and effective treatment for patients with hypercholesterolaemia and combined dyslipidaemia, especially in those with low HDL-C, and it should help improve LDL-C-target attainment rates by reducing the risk of under-treatment, minimising AE rates, and reducing the risk of DDIs in people requiring polypharmacy. Future and ongoing studies will directly compare the effects of pitavastatin vs. other statins on hard clinical

Pitavastatin is a potent HMG-CoA reductase inhibitor and efficient hepatocyte low-density lipoprotein cholesterol (LDL-C) receptor inducer, producing robust reduction of the serum LDL-C levels, even at a low dose. Pitavastatin and its lactone form are minimally metabolized by CYP enzymes, and are therefore associated with minimal drug-drug interactions (DDIs). Pitavastatin 2 to 4 mg has potent LDL-C-reducing activity, equivalent to that of atorvastatin 10 to 20 mg; several clinical trials have revealed consistently superior high-density lipoprotein cholesterol (HDL-C) elevating activity of pitavastatin than that of atorvastatin. Pitavastatin-induced HDL-C elevation has been shown to be sustained, even incremental, in long-term clinical trials. Pitavastatin was as well-tolerated as atorvastatin or simvastatin in double-blind randomized clinical trials. Two-year long-term safety and effectiveness of pitavastain has been confirmed in a large-scale, prospective post-marketing surveillance. The safety and efficacy profile of pitavastatin is favorable for the treatment of dyslipidemia, especially in metabolic syndrome patients. In addition to control of LDL-C, adequate control of triglyceride (TG) and HDL-C, hypertension and hyperglycemia is also necessary in metabolic syndrome patients. Pitavastatin produces adequate control of LDL-C and TG, along with potent and incremental HDL-C elevation, with a low frequency of DDIs.

Statin has been reported to reduce cardiovascular events. However, the comparative efficacy of statin with standard therapy on cardiovascular events has not been sufficiently reported in patients on chronic hemodialysis. Thus, this study aimed to compare the effects of pitavastatin and standard therapy on mortality and cardiovascular events in chronic hemodialysis patients with dyslipidemia in Japan.. Patients on chronic hemodialysis with dyslipidemia were randomized into pitavastatin-administered (pitavastatin group) or dietary therapy as standard therapy (control) group. Primary outcomes are all-cause mortality and myocardial infarction; secondary outcomes are cardiac arrest and fatal myocardial infarction. The composite outcomes included the incidence of coronary intervention, stroke, fracture, and hospitalization due to heart failure and unstable angina. The clinical outcome analyses used a logistic regression model to categorize the variables. A p value of <0.05 was considered statistically significant.. This study included 848 patients (422 in the control group and 426 in the pitavastatin group) from 79 health facilities. The mean age of the patients was 60.1±10.3 years, and the dialysis period was 7.2±7.6 years. The mean observation period was 36.5 months. The low-density lipoprotein cholesterol level was significantly lower than the baseline value in the pitavastatin group after 12 months of trial (79.8±26.1 vs. 107.8±25.5 mg/dL, p < 0.001). Moreover, the total number of deaths was 85, of which 50 occurred in the control group and 35 in the pitavastatin group. In an analysis adjusted for confounding factors due to participant attributes, there was a significant difference between the control group and the pitavastatin group in the primary and composite endpoints (p = 0.007 and p = 0.022, respectively).. Our study has demonstrated that aggressive intervention with pitavastatin is more effective than the standard (dietary) therapy for improving the clinical outcomes in patients with dyslipidemia on chronic hemodialysis.

This study aimed to show that the efficacy of 1PC111 is superior to that of either ezetimibe or pitavastatin alone (monotherapy) for the treatment of hypercholesterolemia.. This was a multicenter, randomized, double-blind, Phase III study. Patients with hypercholesterolemia or mixed dyslipidemia were randomized to receive 1PC111 (which was a fixed-dose combination of pitavastatin 2 mg and ezetimibe 10 mg), pitavastatin 2 mg, or ezetimibe 10 mg daily for 12 weeks. The primary end point was the difference in the percent change in LDL-C from baseline to week 12 between the 1PC111 and each monotherapy group. The secondary end points were the percent change in other lipid profiles from baseline to each visit. All patients were assessed for adverse events until end of study.. A total of 388 patients were randomly assigned to the 1PC111 (n = 128), pitavastatin (n = 132), or ezetimibe (n = 128) group. Generally, baseline characteristics were similar among the 3 groups. A statistically significant decrease in the LDL-C level at week 12 was observed in the 1PC111 group (-50.50% [14.9%]) compared with either the pitavastatin (-36.11% [11.4%]; P < 0.001) or ezetimibe (-19.85% [12.4%]; P < 0.001) group. Also, there was a statistically significant difference between 1PC111 and each monotherapy group in the reduction in total cholesterol, non-HDL-C, and apolipoprotein B levels. Moreover, there was a trend toward more efficient lowering of LDL-C levels in elderly patients (age ≥65 years) than in younger patients (age <65 years) by 1PC111 treatment. In patients given a class I recommendation for atherosclerotic cardiovascular disease prevention, the percentage of patients achieving the LDL-C target of <100 mg/dL at week 12 was significantly higher in the 1PC111 group than in both monotherapy groups (P < 0.001). Overall, the incidence of adverse events was similar among 3 groups.. 1PC111 was more effective in improving lipid profiles and achieving the LDL-C goal than pitavastatin or ezetimibe alone for hypercholesterolemia treatment. Furthermore, 1PC111 may provide more benefit in treating elderly patients.. gov identifier: NCT04643093.

Pitavastatin is a unique lipophilic statin with moderate efficacy in lowering LDL-C levels by 30% to 50% with a tolerable safety profile. However, the efficacy of adding ezetimibe to pitavastatin in patients with dyslipidemia has not been well investigated. Therefore, the objective of this double-blind, multicenter, randomized, Phase III study was to compare the efficacy and safety of pitavastatin and ezetimibe combination therapy with those of pitavastatin monotherapy in Korean patients with primary hypercholesterolemia.. Korean men and women aged >19 and <80 years with primary hypercholesterolemia requiring medical treatment were included in this study. During the 8-week screening period, all patients were instructed to make therapeutic lifestyle changes. The screening period consisted of a 4-week washout period and a placebo run-in period (4-8 weeks). During treatment period I, patients were randomly assigned to receive 1 of 4 treatments: pitavastatin 2 mg plus ezetimibe 10 mg, pitavastatin 2 mg, pitavastatin 4 mg plus ezetimibe 10 mg, or pitavastatin 4 mg. The 8-week double-blind treatment period then commenced. Adverse events (AEs), clinical laboratory data, and vital signs were assessed in all patients.. The percentages in LDL-C from baseline after 8 weeks of double-blind treatment decreased significantly in the pooled pitavastatin/ezetimibe (-52.8% [11.2%]) and pooled pitavastatin (-37.1% [14.1%]) groups. Treatment with pitavastatin/ezetimibe resulted in a significantly greater LDL-C-lowering effect than that with pitavastatin (difference, -15.8 mg/dL; 95% CI, -18.7 to -12.9; P < 0.001). The precentages of achieving LDL-C goal in pooled pitavastatin/ezetimibe and pooled pitavastatin groups were 94.2% and 69.1%, respectively (P < 0.001). There were no significant differences in the incidence of overall AEs and adverse drug reactions. Serious AEs were comparable between the groups.. Pitavastatin and ezetimibe combinations effectively and safely decreased LDL-C levels by >50% in patients with dyslipidemia. The safety and tolerability of pitavastatin and ezetimibe combination therapy were comparable with those of pitavastatin monotherapy.. gov identifier: NCT04584736.

The effects of high-sensitivity C-reactive protein (hs-CRP) levels on clinical outcomes in chronic-phase acute coronary syndrome (ACS) patients undergoing aggressive lipid-lowering therapy remain unclear. We examined the effects of hs-CRP levels on the prognosis of ACS patients who underwent aggressive lipid-lowering therapy and determined treatment targets for hs-CRP value.. This post-hoc sub-analysis of a prospective randomized control trial (HIJ-PROPER) included 1734 ACS patients with dyslipidemia, who were divided into hs-CRP quartiles after 3 months of treatment. Primary endpoints were combined all-cause death, non-fatal myocardial infarction, non-fatal stroke, unstable angina, and ischemia-driven coronary revascularization. Secondary endpoint was all-cause death.. The median follow-up period was 3.7 years. Overall, 1415 patients were evaluated retrospectively. No significant among-group differences were noted in low-density lipoprotein cholesterol (LDL-C) levels over time (p = 0.44). Kaplan-Meier analyses revealed that the incidence of the primary and secondary endpoints was significantly higher in the highest hs-CRP group than in the other groups [hazard ratio (HR) = 1.52, 95% confidence interval (CI) = 1.16-2.00, p < 0.01; HR = 5.30, 95% CI = 2.47-11.32, p < 0.01, respectively]. The cut-off hs-CRP level to predict all-cause death was 0.74 mg/L (receiver operating characteristic curve: sensitivity: 68%, specificity: 62%). Multivariate analyses revealed that hs-CRP ≥0.74 mg/L　at 3 months was correlated with an increased risk of all-cause death (adjusted HR = 3.68, 95% CI = 2.22-6.10, p < 0.01).. Elevated hs-CRP levels independently predicted a worse prognosis, regardless of LDL-C levels, suggesting that interventions against elevated inflammatory responses plus intensive lipid-lowering therapy and coronary revascularization are encouraging options for secondary prevention in ACS patients..

Dyslipidemia is an important risk factor for cardiovascular disease (CVD). Statins are known to effectively reduce not only low-density lipoprotein cholesterol (LDL-C) level but also death and nonfatal myocardial infarction due to coronary heart disease. The risk for CVD from atherogenic dyslipidemia persists when elevated triglyceride (TG) and reduced high-density lipoprotein cholesterol (HDL-C) levels are not controlled with statin therapy. Therefore, statin/fenofibrate combination therapy is more effective in reducing CVD risk. Here, we assessed the efficacy and tolerability of pitavastatin/fenofibrate combination therapy in patients with mixed dyslipidemia and a high risk for CVD.. This multicenter, randomized, double-blind, parallel-group, therapeutic-confirmatory clinical trial evaluated the efficacy and tolerability of fixed-dose combination therapy with pitavastatin/fenofibrate 2/160 mg in Korean patients with a high risk for CVD and a controlled LDL-C level (<100 mg/dL) and a TG level of 150-500 mg/dL after a run-in period with pitavastatin 2 mg alone. In the 8-week main study, 347 eligible patients were randomly assigned to receive pitavastatin 2 mg with or without fenofibrate 160 mg after a run-in period. In the extension study, patients with controlled LDL-C and non-HDL-C (<130 mg/dL) levels were included after the completion of the main study. All participants in the extension study received the pitavastatin/fenofibrate combination therapy for 16 weeks for the assessment of the tolerability of long-term treatment.. The difference in the mean percentage change in non-HDL-C from baseline to week 8 between the combination therapy and monotherapy groups was -12.45% (95% CI, -17.18 to -7.72), and the combination therapy was associated with a greater reduction in non-HDL-C. The changes in lipid profile, including apolipoproteins, fibrinogen, and high-sensitivity C-reactive protein from baseline to weeks 4 and 8 were statistically significant with combination therapy compared to monotherapy at all time points. Furthermore, the rates of achievement of non-HDL-C and apolipoprotein B targets at week 8 in the combination therapy and monotherapy groups were 88.30% versus 77.98% (P = 0.0110) and 78.94% versus 68.45% (P = 0.0021), respectively. The combination therapy was well tolerated, with a safety profile similar to that of statin monotherapy.. In these Korean patients with mixed dyslipidemia and a high risk for CVD, combination therapy with pitavastatin/fenofibrate was associated with a greater reduction in non-HDL-C compared with that with pitavastatin monotherapy, and a significantly improvement in other lipid levels. Moreover, the combination therapy was well tolerated, with a safety profile similar to that of statin monotherapy. Therefore, pitavastatin/fenofibrate combination therapy could be effective and well tolerated in patients with mixed dyslipidemia. ClinicalTrials.gov identifier: NCT03618797.

Background This study aimed to examine the impact of baseline eicosapentaenoic acid (EPA) to arachidonic acid (AA) ratio on clinical outcomes of patients with acute coronary syndrome. Methods and Results In the HIJ-PROPER (Heart Institute of Japan Proper Level of Lipid Lowering With Pitavastatin and Ezetimibe in Acute Coronary Syndrome) study, 1734 patients with acute coronary syndrome and dyslipidemia were randomly assigned to pitavastatin+ezetimibe therapy or pitavastatin monotherapy. We divided the patients into 2 groups based on EPA/AA ratio on admission (cutoff 0.34 μg/mL as median of baseline EPA/AA ratio) and examined their clinical outcomes. The primary end point comprised all-cause death, nonfatal myocardial infarction, nonfatal stroke, unstable angina pectoris, or ischemia-driven revascularization. Percentage reduction of low-density lipoprotein cholesterol and triglyceride from baseline to follow-up was similar regardless of baseline EPA/AA ratio. Despite the mean low-density lipoprotein cholesterol level during follow-up being similar between the low- and high-EPA/AA groups, the mean triglyceride levels during follow-up were significantly higher in the low- than in the high-EPA/AA group. After 3 years of follow-up, the cumulative incidence of the primary end point in patients with low EPA/AA was 27.2% in the pitavastatin+ezetimibe group compared with 36.6% in the pitavastatin-monotherapy group (hazard ratio 0.69; 95% CI, 0.52-0.93; P=0.015). However, there was no effect of pitavastatin+ezetimibe therapy on the primary end point in patients with high EPA/AA (hazard ratio 0.92; 95% CI, 0.70-1.20; P=0.52). Conclusions Among acute coronary syndrome patients who have dyslipidemia and low EPA/AA ratio, adding ezetimibe to statin decreases the risk of cardiovascular events compared with statin monotherapy.

Current guidelines call for high-intensity statin therapy in patients with cardiovascular disease on the basis of several previous "more versus less statins" trials. However, no clear evidence for more versus less statins has been established in an Asian population.. In this prospective, multicenter, randomized, open-label, blinded end point study, 13 054 Japanese patients with stable coronary artery disease who achieved low-density lipoprotein cholesterol (LDL-C) <120 mg/dL during a run-in period (pitavastatin 1 mg/d) were randomized in a 1-to-1 fashion to high-dose (pitavastatin 4 mg/d; n=6526) or low-dose (pitavastatin 1 mg/d; n=6528) statin therapy. The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, or unstable angina requiring emergency hospitalization. The secondary composite end point was a composite of the primary end point and clinically indicated coronary revascularization excluding target-lesion revascularization at sites of prior percutaneous coronary intervention.. High-dose (4 mg/d) compared with low-dose (1 mg/d) pitavastatin therapy significantly reduced cardiovascular events in Japanese patients with stable coronary artery disease..

Hypertension and dyslipidemia are major risk factors for cardiovascular disease (CVD). In 2012, over 270 million patients (25.2%) in China were hypertensive and 40.4% was dyslipidemic. The majority of these patients rely on statins for the prevention of cardiovascular disease. However, certain types of statins (e.g., atorvastatin), compared to others (e.g., pitavastatin), may be associated with unfavorable effects on glucose metabolism. This leads to concerns when prescribing statins to patients who also have a predisposition to glucose metabolic disorders (i.e., prediabetes). Thus, this study aims to investigate the effect of pitavastatin, compared to atorvastatin, on glucose metabolism, as measured by hemoglobin A1c (HbA1c), in Chinese prediabetics with hypertension and dyslipidemias.. The China hemoglobin A1c Metabolism Protection Union Study (CAMPUS) is a multi-center, prospective, open-label, 12-month, two-arm parallel group, and non-inferiority randomized controlled trial (RCT). A total of 396 prediabetics with hypertension and dyslipidemias will be randomly assigned 1:1 to either pitavastatin 2 mg/day or atorvastatin 20 mg/day, and followed for 12 months (follow-up visits at 1, 3, 6, and 12 months) for HbA1c levels, as well as other measures of glucose metabolism, serum lipid levels, blood pressure control, measures of inflammation, vascular endothelial function, carotid atherosclerosis, and hypertension-related left ventricular hypertrophy. If the results of low-density lipoprotein cholesterol (LDL-C) levels in month 3 after treatment initiation do not meet individual target, drug dose for the participant would be doubled.. CAMPUS will be the first RCT to investigate the effect of pitavastatin, compared to atorvastatin, on glucose metabolism in Chinese prediabetics with hypertension and dyslipidemias. Further, this study might eventually provide information to design a clinical strategy, and facilitate the improvement of primary prevention in patients at risk for diabetes and CVD..

People living with HIV-1 infection are at greater risk for cardiovascular disease than seronegative adults. Treatment of dyslipidaemia with statins has been challenging in people with HIV because of an increased potential for drug interactions due to competing cytochrome P450 metabolism between statins and commonly used antiretroviral agents. Neither pitavastatin nor pravastatin depend on cytochrome P450 for primary metabolism. We aimed to assess the safety and efficacy of pitavastatin versus pravastatin in adults with HIV and dyslipidaemia.. In the INTREPID (HIV-infected patieNts and TREatment with PItavastatin vs pravastatin for Dyslipidemia) randomised, double-blind, active-controlled, phase 4 trial (INTREPID, we recruited adults aged 18-70 years with controlled HIV (with CD4 counts >200 cells per μL and HIV-1 RNA <200 copies per mL) on antiretroviral therapy for at least 6 months and dyslipidaemia (LDL cholesterol 3·4-5·7 mmol/L and triglycerides ≤4·5 mmol/L) from 45 sites in the USA and Puerto Rico. Patients being treated with darunavir, or who had homozygous familial hypercholesterolaemia or any condition causing secondary dyslipidaemia, or a history of statin intolerance, diabetes, or coronary artery disease were not eligible. We randomly assigned patients (1:1) to pitavastatin 4 mg or pravastatin 40 mg with matching placebos once daily orally for 12 weeks, followed by a 40 week safety extension. Randomisation was stratified by viral hepatitis B or C coinfection and computer-generated. Investigators, patients, study staff, and those assessing outcomes were masked to treatment group. The primary endpoint was percentage change in fasting serum LDL cholesterol from baseline to week 12 and the primary efficacy analysis was done in the modified intention-to-treat population. The safety analysis included all patients who took at least one dose of study medication. This study is registered with ClinicalTrials.gov, number NCT01301066.. Between Feb 23, 2011, and March 29, 2013, we randomly assigned 252 patients to the pitavastatin (n=126) or pravastatin group (n=126). LDL cholesterol reduction was 31·1% with pitavastatin and 20·9% with pravastatin (least squares mean difference -9·8%, 95% CI -13·8 to -5·9; p<0·0001) at 12 weeks. At week 52, four patients (3%) in the pitavastatin group and six (5%) in the pravastatin group had virological failure, with no significant difference between treatments. Both treatments had neutral effects on glucose metabolism parameters. 85 patients treated with pitavastatin (68%) and 88 patients treated with pravastatin (70%) reported treatment-emergent adverse events, and these caused study discontinuation in six patients (5%) versus five patients (4%). No serious adverse event occurred in more than one participant and none were treatment-related according to investigator assessment. The most common treatment-emergent adverse events were diarrhoea in the pitavastatin group (n=12, 10%) and upper respiratory tract infection in the pravastatin group (n=14, 11%). 11 treatment-emergent serious adverse events were noted in seven patients (6%) in the pitavastatin group (atrial septal defect, chronic obstructive pulmonary disease, chest pain, diverticulitis, enterovesical fistula, gastroenteritis, viral gastroenteritis, herpes dermatitis, multiple fractures, respiratory failure, and transient ischaemic attack) and four events in three patients (2%) in the pravastatin group (cerebrovascular accident, arteriosclerosis coronary artery, myocardial infraction, and muscle haemorrhage). In the pravastatin treatment group, one additional patient discontinued due to an adverse event (prostate cancer that was diagnosed during the screening period, 42 days before first dose of study treatment, and therefore was not a treatment-emergent adverse event).. The INTREPID results support guideline recommendations for pitavastatin as a preferred drug in the treatment of dyslipidaemia in people with HIV..

To elucidate the effects of intensive LDL-C lowering treatment with a standard dose of statin and ezetimibe in patients with dyslipidaemia and high risk of coronary events, targeting LDL-C less than 70 mg/dL (1.8 mmol/L), compared with standard LDL-C lowering lipid monotherapy targeting less than 100 mg/dL (2.6 mmol/L).. The HIJ-PROPER study is a prospective, randomized, open-label trial to assess whether intensive LDL-C lowering with standard-dose pitavastatin plus ezetimibe reduces cardiovascular events more than standard LDL-C lowering with pitavastatin monotherapy in patients with acute coronary syndrome (ACS) and dyslipidaemia. Patients were randomized to intensive lowering (target LDL-C < 70 mg/dL [1.8 mmol/L]; pitavastatin plus ezetimibe) or standard lowering (target LDL-C 90 mg/dL to 100 mg/dL [2.3-2.6 mmol/L]; pitavastatin monotherapy). The primary endpoint was a composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, unstable angina, and ischaemia-driven revascularization. Between January 2010 and April 2013, 1734 patients were enroled at 19 hospitals in Japan. Patients were followed for at least 36 months. Median follow-up was 3.86 years. Mean follow-up LDL-C was 65.1 mg/dL (1.68 mmol/L) for pitavastatin plus ezetimibe and 84.6 mg/dL (2.19 mmol/L) for pitavastatin monotherapy. LDL-C lowering with statin plus ezetimibe did not reduce primary endpoint occurrence in comparison with standard statin monotherapy (283/864, 32.8% vs. 316/857, 36.9%; HR 0.89, 95% CI 0.76-1.04, P = 0.152). In, ACS patients with higher cholesterol absorption, represented by elevated pre-treatment sitosterol, was associated with significantly lower incidence of the primary endpoint in the statin plus ezetimibe group (HR 0.71, 95% CI 0.56-0.91).. Although intensive lowering with standard pitavastatin plus ezetimibe showed no more cardiovascular benefit than standard pitavastatin monotherapy in ACS patients with dyslipidaemia, statin plus ezetimibe may be more effective than statin monotherapy in patients with higher cholesterol absorption; further confirmation is needed..

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality in those with HIV. An emerging CVD risk factor is triglyceride-rich remnant lipoprotein cholesterol (RLP-C: the sum of intermediate-density lipoprotein and very low-density lipoprotein cholesterol). The effects of statin therapy on lipoprotein subfractions, including RLP-C, in HIV dyslipidemia are unknown.. This is a post hoc analysis of the randomized INTREPID trial (NCT 01301066) comparing pitavastatin 4 mg daily vs. pravastatin 40 mg daily in study participants with HIV. We measured apolipoproteins AI and B and lipoprotein cholesterol subfractions separated by density gradient ultracentrifugation at baseline and 12 weeks. We compared changes in atherogenic subfractions over 12 weeks in INTREPID participants using analysis of covariance.. Lipoprotein subfraction data were available for 213 study participants (pitavastatin n = 104, pravastatin n = 109). Baseline characteristics were similar between treatment groups. Reductions in RLP-C were significantly greater in the pitavastatin group compared with pravastatin group (-11.6 mg/dl vs. -8.5 mg/dl; P = 0.01). Similarly, ratios of risk [apolipoproteins B/apolipoproteins AI, total cholesterol/high-density lipoprotein cholesterol (HDL-C)] showed greater reductions with pitavastatin (P < 0.05). There were no differences in changes in HDL-C, HDL-C subfractions or lipoprotein(a) cholesterol levels.. In patients with HIV, pitavastatin 4 mg/dl lowered both RLP-C and established apolipoprotein and lipid risk ratios more so than pravastatin 40 mg/dl. The impact of RLP-C reduction on CVD in HIV dyslipidemic patients merits further study.

The purpose of this study was to evaluate the efficacy and safety of LIVALO tablets (pitavastatin) in Japanese male children with heterozygous familial hypercholesterolemia (FH).. A multicenter, randomized, double-blind, parallel study was conducted in 14 male children 10-15 years of age with heterozygous FH. Pitavastatin (1 mg/day or 2 mg/day) was administered orally for 52 weeks.The primary endpoint was the percent change in the LDL-cholesterol (LDL-C) concentrations from baseline to endpoint (repeated measures ANCOVA at Weeks 8 and 12). Secondary endpoints included the percentage of patients who achieved the target LDL-C concentration and percent changes in the levels of lipoprotein and lipid parameters at the visit performed at 52 weeks.. The percent change in LDL-C from baseline (mean 258 mg/dL for all patients) to the endpoint was -27.3% (95%CI; -34.0, -20.5) and -34.3% (95%CI; -41.0, -27.5) in the patients receiving 1 mg and 2 mg of pitavastatin, respectively. Stable reductions in the total cholesterol (TC), non-HDL cholesterol (non-HDL-C), apolipoprotein B (Apo-B) and LDL-C levels and non-HDL-C/HDL-C and Apo-B/Apo-A1 ratios were observed up to 52 weeks in both groups. One patient in each dose group (14%) reached the treatment target level of 130 mg/dL.Adverse events were observed in seven (100%) patients receiving 1 mg and five (71%) patients receiving 2 mg of pitavastatin, although none were considered related to the study treatment. One patient in the 1 mg group reported a musculoskeletal AE; however, it was attributed to recent excessive exercise.. Pitavastatin significantly reduced the LDL-C levels and was well tolerated when administered at usual adult doses in 14 male children 10-15 years of age with heterozygous FH. Pitavastatin is a promising therapeutic agent for pediatric dyslipidemia with few safety concerns.

Remnants are partially hydrolyzed, triglyceride-rich lipoproteins that are implicated in atherosclerosis. We assessed the adequacy of pitavastatin 4 mg and pravastatin 40 mg in reducing atherogenic lipid parameters beyond LDL-C, in particular remnant lipoprotein cholesterol (RLP-C).. From the Phase IV, multicenter, randomized, double-blind PREVAIL US (A Study of Pitavastatin 4 mg Vs. Pravastatin 40 mg in Patients With Primary Hyperlipidemia or Mixed Dyslipidemia) trial, we examined lipoprotein cholesterol subfractions using Vertical Auto Profile testing and apolipoproteins B and A-I at baseline and 12 weeks. Participants with primary hyperlipidemia or mixed dyslipidemia had LDL-C levels of 130 to 220 mg/dL and triglyceride levels ≤ 400 mg/dL. In this post hoc analysis, changes in lipid parameters were compared by using ANCOVA.. Lipoprotein subfraction data were available in 312 patients (pitavastatin, n = 157; pravastatin, n = 155). Pitavastatin promoted a greater reduction in RLP-C than pravastatin (-13.6 [8.7] vs -9.3 [9.5] mg/dL). Furthermore, the pitavastatin group reported greater reductions in both components of RLP-C (both, P < 0.001): intermediate-density lipoprotein cholesterol (-9.5 [6.3] vs -6.4 [6.6] mg/dL) and very low-density lipoprotein cholesterol subfraction 3 (-4.1 [3.5] vs -2.9 [3.8] mg/dL). There were also greater reductions in the major ratios of risk (apolipoprotein B/apolipoprotein A-I and total cholesterol/HDL-C) (both, P < 0.001). There were no significant changes in HDL-C, its subfractions, or natural log lipoprotein(a)-cholesterol. The mean age was 58.8 ± 8.9 years in the pitavastatin group and 57.0 ± 10.2 years in the pravastatin group.. Compared with pravastatin 40 mg daily, pitavastatin 4 mg provided superior reductions in atherogenic lipid parameters beyond LDL-C, including RLP-C. Future studies are needed investigate the clinical implications of lowering directly measured RLP-C as the principal target. ClinicalTrials.gov identifier: NCT01256476.

Dyslipidemia as a risk factor of cardiovascular disease is common especially in HIV-infected patients who are using protease inhibitors (PIs) including atazanavir. Pitavastatin has less drug-drug interactions and demonstrable efficacy in decreasing lipid levels in non HIV-infected individuals.. This study was a randomized, double-blind, crossover study comparing the safety and efficacy of pitavastatin vs placebo in HIV-infected patients with dyslipidemia and receiving atazanavir/ritonavir (ATV/r). Patients were randomized to receive either placebo or pitavastatin for 12 weeks. The follow-up visits were every 4 weeks until the end of the study.. A total of 12 HIV-infected patients were enrolled to each study group. Of all, 14 (58%) patients were men and mean (standard deviation, SD) age was 48.1 (1.8) years. At 12 weeks of treatment with pitavastatin compared to placebo; mean [95% confidence interval (CI)] total cholesterol (TC) was 207 (187.3, 226.8) mg/dL vs 246.3 (226.5, 266) mg/dL (p <0.001); mean (95% CI) triglyceride (TG) was 351.3 (193.2, 509.4) mg/dL vs 279.1 (121, 437.2) mg/dL (p = 0.269); mean (95% CI) high density lipoprotein (HDL) was 45.3 (40.4, 50.2) mg/dL vs 44.2 (39.3, 49.1) mg/dL (p = 0.354); and mean (95% CI) low density lipoprotein (LDL) was 113.2 (100.4, 126) mg/dL vs 145.6 (132.8, 158.4) mg/dL (p <0.001). Mean liver enzyme and median creatine phosphokinase levels were not statistically significant between patients receiving placebo and pitavastatin.. Pitavastatin decreases TC and LDL level at 12 weeks significantly and shows indifferent in hepatotoxicity and creatine phosphokinase levels compared to those of placebo. Thus, pitavastatin can be a good option of lipid-lowering agent in HIV-infected patients who are receiving ATV/r.. ClinicalTrials.gov NCT02442700.

Atherogenic mixed dyslipidemia associates with oxidative stress and defective HDL antioxidative function in metabolic syndrome (MetS). The impact of statin treatment on the capacity of HDL to inactivate LDL-derived, redox-active phospholipid hydroperoxides (PCOOHs) in MetS is indeterminate. Insulin-resistant, hypertriglyceridemic, hypertensive, obese males were treated with pitavastatin (4 mg/day) for 180 days, resulting in marked reduction in plasma TGs (-41%) and LDL-cholesterol (-38%), with minor effects on HDL-cholesterol and apoAI. Native plasma LDL (baseline vs. 180 days) was oxidized by aqueous free radicals under mild conditions in vitro either alone or in the presence of the corresponding pre- or poststatin HDL2 or HDL3 at authentic plasma mass ratios. Lipidomic analyses revealed that statin treatment i) reduced the content of oxidizable polyunsaturated phosphatidylcholine (PUPC) species containing DHA and linoleic acid in LDL; ii) preferentially increased the content of PUPC species containing arachidonic acid (AA) in small, dense HDL3; iii) induced significant elevation in the content of phosphatidylcholine and phosphatidylethanolamine (PE) plasmalogens containing AA and DHA in HDL3; and iv) induced formation of HDL3 particles with increased capacity to inactivate PCOOH with formation of redox-inactive phospholipid hydroxide. Statin action attenuated LDL oxidability Concomitantly, the capacity of HDL3 to inactivate redox-active PCOOH was enhanced relative to HDL2, consistent with preferential enrichment of PE plasmalogens and PUPC in HDL3.

HMG-CoA reductase inhibitors, also termed statins, are used to reduce the risk of coronary artery disease. Two oxidatively modified low-density lipoprotein (LDL) complexes, serum amyloid A-LDL (SAA-LDL) and α1-antitrypsin-LDL (AT-LDL), serve as atherosclerotic, inflammatory, and cardiovascular risk markers. In this study, we examined the effects of hydrophilic rosuvastatin (RSV) and lipophilic pitavastatin (PTV) on these markers in patients with hypercholesterolemia.. The present study was a sub-analysis of our previous STAT-LVDF study. The subjects were treated with RSV or PTV for 24weeks. Changes in glucose-lipid metabolism, serum levels of SAA-LDL and AT-LDL, and C-reactive protein (CRP) level were assessed.. In total, 53 patients were analyzed in the present study. RSV and PTV significantly decreased SAA-LDL (RSV: p=0.003, PTV: p=0.012) and AT-LDL levels (RSV: p=0.013, PTV: p=0.037). Changes in SAA-LDL level were significantly and positively correlated with those in CRP in both the RSV (r=0.549, p=0.003) and PTV (r=0.576, p=0.004) groups. Moreover, a positive correlation between changes of SAA-LDL levels and those of HbA1c levels was observed in the PTV group (r=0.442, p=0.030) but not in the RSV group (r=-0.100, p=0.611).. Both hydrophilic rosuvastatin and lipophilic pitavastatin reduce serum levels of atherosclerotic and inflammatory markers. These findings also indicate differential effects of RSV and PTV on glucose tolerance.

Dyslipidaemia and central obesity are the major factors underlying the dramatic increase in metabolic syndrome (MS). We compared the effects of early combined therapy with pitavastatin and intensive lifestyle modification (LSM) on the amelioration of each component of MS with those of LSM only.. PROPIT (a PROspective comparative clinical study to evaluate the efficacy and safety of PITavastatin in patients with metabolic syndrome) was a prospective, randomized, multicenter open-label 48-week trial. We enrolled 187 patients with MS (central obesity and prediabetes) and randomized them into two treatment groups: 2 mg pitavastatin daily + intensive LSM or intensive LSM only. The primary outcome was the improvements in the components of MS and in the percentage of non-MS converters.. After 1 year treatment, the improvement of MS score was significantly higher in the pitavastatin + LSM group (P = 0·039). However, non-MS converters (MS score ≤2) did not differ between the groups. The secondary outcomes, namely lipid profiles, the Apo B/A1 ratio, visceral fat/subcutaneous fat ratio and the Framingham risk score, were significantly improved in the pitavastatin group. There was no deterioration in glucose metabolism after treatment with pitavastatin for 1 year.. Early statin treatment can be an effective option in obese patients with MS, prediabetes and mild dyslipidaemia with further improvement of cardiovascular risk factors. We could not observe the increase rate of glucose intolerance in statin group. Future longitudinal studies are needed to test the benefits of early statin treatment compared with LSM.

3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) have multiple pleiotropic effects, such as anti-inflammatory and vascular endothelium protection, that are independent of their low-density-lipoprotein (LDL) cholesterol lowering effects. However, whether different statins exert diverse effects on inflammation, insulin resistance, and the progression of carotid atherosclerosis [as indicated by the intima-media thickness (CIMT)] in patients with dyslipidemia remains unclear.. A total of 146 patients with hypercholesterolemia without known cardiovascular disease were randomly assigned to receive 5 mg/day of atorvastatin (n=73) or 1 mg/day of pitavastatin (n=73).. At baseline, age, gender, blood pressure, lipid profiles, and the serum monocyte chemoattractant protein (MCP)-1, homeostasis model assessment of insulin resistance (HOMA-IR) and CIMT values were comparable between the groups. After 12 months of treatment, atorvastatin and pitavastatin equally reduced the LDL cholesterol levels; however, atorvastatin increased the HOMA-IR by ＋26% and pitavastatin decreased this parameter by －13% (p＜0.001). The MCP-1 values were reduced by －28% in the patients treated with pitavastatin and only －11% in those treated with atorvastatin (p=0.016). A greater percent decrease in the mean CIMT from baseline was observed in the patients treated with pitavastatin than in those treated with atorvastatin (－4.9% vs. －0.5%, p=0.020).. These data indicate that, while these agents significantly and equally reduce the LDL cholesterol levels, atorvastatin and pitavastatin have different effects on inflammation, insulin resistance, and the progression of carotid atherosclerosis in patients with dyslipidemia.

The effects of statins on serum n-3 to n-6 polyunsaturated fatty acids (PUFAs) levels have not been fully evaluated. We examined the effects of two types of statins (rosuvastatin and pitavastatin) on serum PUFAs levels and their ratios in patients with dyslipidemia.. A total of 46 patients who were not receiving lipid-lowering therapy were randomly assigned to receive either 2.5 mg/day of rosuvastatin or 2 mg/day of pitavastatin. Serum PUFAs levels were measured at baseline, at 4 weeks, and at 12 weeks. Rosuvastatin was used to treat 23 patients, and the remaining 23 patients were treated using pitavastatin. Serum docosahexaenoic acid (DHA) levels decreased significantly at 12 weeks in both groups (rosuvastatin: from 169.6 to 136.3 μg/mL, p = 0.006; pitavastatin: from 188.6 to 153.9 μg/mL, p = 0.03). However, serum levels of eicosapentaenoic acid (EPA) and arachidonic acid (AA) did not change. In addition, the EPA/AA ratio did not change, whereas the DHA/AA ratio decreased significantly at 12 weeks in both groups (rosuvastatin: from 0.99 to 0.80, p = 0.01; pitavastatin: from 1.14 to 0.91, p = 0.003). No adverse events were observed during the study period.. In this small, open-label, pilot study, rosuvastatin and pitavastatin decreased serum DHA levels and the DHA/AA ratio in patients with dyslipidemia.

To determine the lipid lowering effectiveness, cost effectiveness, and safety of rosuvastatin compared with pitavastatin in dyslipidemic patients with concurrent renal disorders.. This single-center, prospective, open-label, randomized, 12-month study evaluated rosuvastatin (2.5 mg) and pitavastatin (1 or 2 mg) in 134 dyslipidemic patients with concurrent chronic kidney disease (CKD; rosuvastatin group, n=68; pitavastatin group, n=66). Lipid parameters [i.e., low density lipoprotein cholesterol (LDL-C), etc.], renal function parameters [i.e., estimated glomerular filtration rate (eGFR), etc.], glycated hemoglobin (HbA1c), and high-sensitivity C-reactive protein (hs-CRP) were measured at enrollment (baseline), month 6, and month 12.. The mean daily dose of rosuvastatin and pitavastatin was 2.5 mg and 1.4 mg, respectively. All lipid parameters were significantly more improved in the rosuvastatin group. eGFR improved from baseline in the rosuvastatin group (p ＜ 0.0001) and showed no tendency to worsen in the pitavastatin group (p=0.2232). In multiple regression analysis (n=134), it was significantly associated with a percent change in total cholesterol (β=0.2296; p=0.0112), smoking (β=0.1927; p=0.0224), and HbA1c (β=-0.1606; p=0.0585). Hs-CRP was significantly improved in both groups. An analysis eliminating the influence of antidiabetic medication showed a significant difference between groups in the change of HbA1c at month 6 from baseline (p=0.0016). No subjects in either group had new onset of diabetes mellitus. The cost of statin medication required to reduce LDL-C by 10 mg/dL was significantly lower for 2.5 mg of rosuvastatin (p=0.0116).. Rosuvastatin 2.5 mg had superior lipid lowering and cost effectiveness in dyslipidemic patients with concurrent CKD.(UMIN ID: UMIN000005812).

Statins, 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase inhibitors, are potential drugs for chronic heart failure treatment in clinical studies. However, there may be differences in the effects on heart failure between lipophilic and hydrophilic statins. In this study, we investigated whether hydrophilic rosuvastatin (RSV) and lipophilic pitavastatin (PTV) exert different effects on the left ventricular diastolic function. Subjects were hypercholesterolemia patients with left ventricular diastolic dysfunction. This was an open-label, randomized, parallel, comparative, prospective study. The subjects received treatment with RSV or PTV for 24 weeks, and their low density lipoprotein (LDL)-cholesterol levels were controlled by these statins according to the guideline. The primary endpoint was defined as the change in left ventricle (LV) diastolic function (E/E') estimated by echocardiography, and the secondary endpoint was the plasma B-type natriuretic peptide (BNP) level. No serious adverse effects were observed during the entire study period in any patient, nor were there any significant differences in changes in the body mass index, blood pressure, or heart rate. Statin treatment did not significantly alter the primary endpoint, E/E'. The change ratio of BNP was not significantly different between PTV and RSV groups. However, BNP was significantly increased in the RSV (p=0.030) but not the PTV (p>0.999) group. This study revealed that although neither RSV nor PTV improved LV diastolic dysfunction, BNP, a biomarker of LV wall stress, was increased in the RSV but not the PTV group. Observation for a longer period is necessary to clarify the different effects of these statins on LV diastolic dysfunction. (UMIN-ID: UMIN000003571).

In non-dialysis chronic kidney disease (CKD) patients with dyslipidemia, statin therapy is recommended to prevent cardiovascular complications. Dyslipidemia has been also shown to be an independent risk factor for the progression of CKD. However, it is still unclear whether statin therapy exerts an inhibitory effect on renal deterioration in CKD patients with dyslipidemia. The purpose of the present study was to examine possible therapeutic effects of statin add-on therapy on renal function as well as parameters of lipid and glucose metabolism, arterial stiffness and oxidative stress, in comparison to diet therapy, in CKD patients with dyslipidemia.. This study was a randomized, open-label, and parallel-group trial consisted of a 12-months treatment period in non-dialysis CKD patients with alubuminuria and dyslipidemia. Twenty eight patients were randomly assigned either to receive diet counseling alone (diet therapy group) or diet counseling plus pitavastatin (diet-plus-statin therapy group), to achieve the LDL-cholesterol (LDL-C) target of <100 mg/dl.. The statin treatment by pitavastatin was well tolerated in all of the patients without any significant adverse events and the average dose of pitavastatin was 1.0 ± 0.0 mg daily after treatment. After the 12-months treatment period, LDL-C was significantly lower in the diet-plus-statin therapy group compared with the diet therapy group (diet vs diet-plus-statin: LDL-C, 126 ± 5 vs 83 ± 4 mg/dL, P < 0.001). On the other hand, the diet-plus-statin therapy did not significantly reduce albuminuria or delay the decline in eGFR compared with the diet therapy, and there was no relationship between the change in LDL-C and the change in eGFR or albuminuria. However, diet therapy as well as diet-plus-statin therapy exerted similar lowering effects on the pentosidine levels (diet therapy group, baseline vs 12 months: 40 ± 4 vs 24 ± 3 ng/mL, P = 0.001; diet-plus-statin therapy, 46 ± 7 vs 34 ± 6 ng/mL, P = 0.008). Furthermore, the results of multivariate regression analysis indicated that the change in pentosidine was a significant contributor to the change in eGFR (β = -0.536, P = 0.011).. Although statin add-on therapy did not show additive renal protective effects, the diet therapy as well as the diet-plus-statin therapy could contribute to the reduction in plasma pentosidine in CKD patients with albuminuria and dyslipidemia.

Low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular risk. However, some patients show symptoms of coronary heart disease (CHD) even though their LDL-C is strictly controlled. Therefore, it is important to treat other risk factors.. Some 129 outpatients with dyslipidemia who were treated with either atorvastatin 10 mg/day (ATO), pitavastatin 2 mg/day (PIT), or rosuvastatin 2.5 mg/day (ROS) were enrolled. After informed consent was obtained, these patients were switched to another statin. Lipid profiles and lipoprotein fraction by polyacrylamide gel electrophoresis (PAGE) were compared between before and after 3 months of treatment with non-fasting blood sample.. LDL-C did not show any significant changes after switching and was maintained around 2.59 mmol/L in all groups. High-density lipoprotein cholesterol (HDL-C) was significantly increased in group ATO→PIT (1.43→1.54 mmol/L, p = 0.0010) and ROS→PIT (1.46→1.57 mmol/L, p = 0.0004), and was significantly decreased in group PIT→ATO (1.44→1.36 mmol/L, p = 0.0290). Apolipoprotein A-I (Apo A-I) and preheparin lipoprotein lipase (LPL) mass showed similar changes in HDL-C. Changes in HDL-C showed a significant positive correlation with those in Apo A-I and preheparin LPL mass, and a little but significant negative correlation with changes in Lp(a) and intermediate density lipoprotein (IDL) fraction.. ATO, PIT, and ROS have comparable effect on LDL-C lowering. Changes in HDL-C were similar to those in Apo A-I and preheparin LPL mass, and PIT was the most effective treatment in increasing HDL-C, Apo A-I, and preheparin LPL mass.

Results from a Phase III, European, non-inferiority trial in elderly (age ≥65 years) patients with primary hyperlipidemia or mixed (combined) dyslipidemia demonstrated significantly greater reductions in LDL-C for pitavastatin versus pravastatin across 3 pair-wise dose comparisons (1 mg vs 10 mg, 2 mg vs 20 mg, and 4 mg vs 40 mg, respectively). The present study investigated whether pitavastatin 4 mg is superior to pravastatin 40 mg in LDL-C reduction in adults (18-80 years old) with primary hyperlipidemia or mixed (combined) dyslipidemia.. This was a Phase IV, multicenter, randomized, double-blind, double-dummy, active-control superiority study conducted in the United States. Patients with baseline LDL-C levels of 130 to 220 mg/dL (inclusive) and triglyceride levels ≤400 mg/dL after a 6-week washout/dietary stabilization period were randomized to 12 weeks of once-daily treatment with either pitavastatin 4 mg or pravastatin 40 mg.. A total of 328 subjects (164 per treatment arm) were randomized (mean age, 57.9 years [76% were aged <65 years]; 49.4% women; mean body mass index, 30.2 kg/m(2)) to treatment. The median percent change in LDL-C from baseline to the week 12 endpoint was -38.1% for pitavastatin 4 mg and -26.4% for pravastatin 40 mg; the difference in median percent change between treatments was -12.5% (P < 0.001). Differences between treatments in median percent reductions from baseline for apolipoprotein B, total cholesterol, and non-HDL-C were also significant in favor of pitavastatin (P < 0.001). Both treatments significantly (P < 0.001) increased HDL-C and decreased triglycerides, but the differences between treatments were not statistically significant. The overall rate of treatment-emergent adverse events was 47.6% (78 of 164) for pitavastatin and 44.5% (73 of 164) for pravastatin. Myalgia was reported by 3 patients (1.8%) in the pitavastatin group and by 4 patients (2.4%) in the pravastatin group. There were no reports of myositis or rhabdomyolysis.. Pitavastatin 4 mg demonstrated superior LDL-C reductions compared with pravastatin 40 mg after 12 weeks of therapy in adults with primary hyperlipidemia or mixed (combined) dyslipidemia. There were no new safety findings in the trial. Clinical Trials.gov identifier: NCT01256476.

This study was designed to evaluate the dose-effect relationship of statins in patients with ischemic congestive heart failure (CHF), since the role of statins in CHF remains unclear.. The South koreAn Pitavastatin Heart FaIluRE (SAPHIRE) study was designed to randomize patients with ischemic CHF into daily treatments of 10 mg pravastatin or 4 mg pitavastatin.. The low density lipoprotein cholesterol level decreased by 30% in the pitavastatin group compared with 12% in the pravastatin (p < 0.05) group. Left ventricular systolic dimensions decreased significantly by 9% in the pitavastatin group and by 5% in the pravastatin group. Left ventricular ejection fraction (EF) improved significantly from 37% to 42% in the pitavastatin group and from 35% to 39% in the pravastatin group. Although the extent of the EF change was greater in the pitavastatin group (16% vs. 11%) than that in the pravastatin group, no significant difference was observed between the groups (p = 0.386). Exercise capacity, evaluated by the 6-min walking test, improved significantly in the pravastatin group (p < 0.001), but no change was observed in the pitavastatin group (p = 0.371).. Very low dose/low potency pravastatin and high dose/high potency pitavastatin had a beneficial effect on cardiac reverse remodeling and improved systolic function in patients with ischemic CHF. However, only pravastatin significantly improved exercise capacity. These findings suggest that lowering cholesterol too much may not be beneficial for patients with CHF.

To assess the long-term efficacy, safety and tolerability of pitavastatin (2 and 4 mg) in elderly patients (≥ 65 years of age) with primary hypercholesterolaemia or combined (mixed) dyslipidaemia.. Patients (n = 545) who had completed a 12-week double-blind comparative study (core study) of pitavastatin and pravastatin entered a 60-week, open-label, multicentre extension study of pitavastatin. The initial daily dose was 2 mg, increasing to 4 mg after 8 weeks if necessary to achieve treatment targets. The proportion of patients attaining European Atherosclerosis Society (EAS) and National Cholesterol Education Program Adult Treatment Plan III (NCEP ATP III) targets for low-density lipoprotein cholesterol (LDL-C) was determined.. Of the patients enrolled, 539 received at least one dose of pitavastatin (safety population: men, 45.5%; Caucasian, 99.1%; mean age, 70.3 years; range, 65-89 years). Only 17% of patients required up-titration to pitavastatin 4 mg. After 60 weeks, NCEP ATP III and EAS targets were attained by 93.8% and 89.0% of patients, respectively. Plasma LDL-C declined by 43.4% and high-density lipoprotein cholesterol increased by 9.6% versus core-study baseline values. Pitavastatin was well tolerated: the most common treatment-emergent adverse events were nasopharyngitis, mild/moderate myalgia and hypertension. There were no cases of severe myalgia, myopathy, myositis or rhabdomyolysis, and no significant findings on urinalysis, vital signs or 12-lead ECG.. Long-term pitavastatin treatment (2 and 4 mg) is effective in lowering LDL-C levels and has a good safety and tolerability profile in elderly patients.

To compare the safety and efficacy of once-daily pitavastatin (1, 2, and 4 mg) and pravastatin (10, 20, and 40 mg) in elderly patients (≥ 65 years of age) with primary hypercholesterolaemia or combined (mixed) dyslipidaemia.. After a 6-8-week washout/dietary period, patients were randomized to six treatment groups (1, 2, or 4 mg pitavastatin vs. 10, 20, or 40 mg pravastatin) in a 12-week multicentre double-blind study. Patients (n = 942; men, 44.3%; Caucasian, 99.3%; mean age, 70 years; age range, 65-89 years) in all groups were well matched for duration of disease and diagnosis.. Mean decreases in low-density lipoprotein cholesterol over 12 weeks were 31.4-44.3% with pitavastatin 1-4 mg and 22.4-34.0% with pravastatin 10-40 mg (p < 0.001 for all dose comparisons). Compared with pravastatin, pitavastatin provided greater decreases in total cholesterol and apolipoprotein B in all dose groups (p < 0.001) and triglycerides in the low-dose (p = 0.001) and higher-dose (p = 0.016) groups, and greater increases in high-density lipoprotein cholesterol in the intermediate-dose (p = 0.013) and higher-dose (p = 0.023) groups. The proportions of patients achieving the European Atherosclerosis Society target with pitavastatin and pravastatin, respectively, were: low doses, 59.9 and 37.9%; intermediate doses, 79.5 and 51.0%; higher doses, 88.1 and 65.7% (p < 0.001 for all comparisons). Both statins were well tolerated, with no reports of myopathy or rhabdomyolysis.. Pitavastatin provides superior efficacy and comparable tolerability to pravastatin in elderly patients.

Renal dysfunction is an independent risk factor for cardiovascular events. However, little is known regarding the impacts of renal dysfunction on coronary atherosclerosis.. The effects of 8-month statin therapy on coronary atherosclerosis were evaluated in the TRUTH study using virtual histology intravascular ultrasound in 164 patients with angina pectoris. We analyzed correlations between the estimated glomerular filtration rate (eGFR) and coronary atherosclerosis before and during statin therapy.. Baseline eGFR was 64.5 mL/min per 1.73 m(2) . Serum low-density lipoprotein cholesterol level decreased significantly from 132 to 85 mg/dL (-35%, P < 0.0001) after 8 months. Weak, but significant, negative correlations were observed between eGFR and external elastic membrane volume (r = -0.228, P = 0.01) and atheroma volume (r = -0.232, P = 0.01) at baseline. The eGFR was also negatively correlated with fibro-fatty volume (r = -0.254, P = 0.005) and fibrous volume (r = -0.241, P = 0.008) at baseline. Multivariate regression analyses showed that eGFR was a significant independent predictor associated with statin pre-treatment volume in fibro-fatty (β = -0.23, P = 0.01) and fibrous (β = -0.203, P = 0.02) components. Furthermore, eGFR was positively correlated with volume change in the fibro-fatty component during statin therapy (r = 0.215, P = 0.02).. Decreased eGFR is associated with expanding remodelling and a greater atheroma volume, particularly the fibro-fatty and fibrous volume before statin therapy in patients with normal to mild renal dysfunction. Reduction of fibro-fatty volume during statin therapy gradually accelerated with decreasing renal function.

Oxidized LDL accelerates vascular endothelial damage and the progression of early arteriosclerosis, and is known as an independent risk factor for coronary artery disease. In this study, we administered pioglitazone and pitavastatin for 16 weeks to 18 patients who had type 2 diabetes complicated by dyslipidemia and then investigated the influence of these 2 drugs on MDA-LDL(i. e., oxidized LDL). As a result, a significant decrease of MDA-LDL was observed in both groups, but a significant decrease of the MDA-LDL/LDL-C ratio (an indicator of the extent of oxidation of LDL) was only observed in the pioglitazone group. Accordingly, it was demonstrated that pioglitazone improves oxidative stress, and the possibility was suggested that the MDA-LDL/LDL-C ratio is useful for the evaluation of oxidative stress in clinical practice.

To compare the long-term efficacy and safety of pitavastatin with atorvastatin in patients with type 2 diabetes and combined (mixed) dyslipidaemia.. Randomised, double-blind, active-controlled, multinational non-inferiority study. Patients were randomised 2 : 1 to pitavastatin 4 mg (n = 279) or atorvastatin 20 mg (n = 139) daily for 12 weeks. Patients completing the core study could continue on pitavastatin 4 mg (n = 141) or atorvastatin 20 mg (n = 64) [40 mg (n = 7) if lipid targets not reached by week 8] for a further 44 weeks (extension study). The primary efficacy variable was the change in low-density lipoprotein cholesterol (LDL-C).. Reductions in LDL-C were not significantly different at week 12 between the pitavastatin (-41%) and atorvastatin (-43%) groups. Attainment of National Cholesterol Education Program and European Atherosclerosis Society targets for LDL-C and non-high-density lipoprotein cholesterol (non-HDL-C) was similarly high for both treatment groups. Changes in secondary lipid variables (e.g. HDL-C, apolipoprotein B and triglycerides) were similar between treatments. Post hoc analysis showed that adjusted mean treatment differences for pitavastatin vs. atorvastatin were within the non-inferiority margin at weeks 16 (+0.11%; 95% confidence interval (CI), -5.23 to 5.44) and 44 (-0.02%; 95% CI, -5.46 to 5.41) of the extension study. Both treatments were well tolerated; atorvastatin increased fasting blood glucose from baseline (+7.2%; p < 0.05), whereas pitavastatin had no significant effect (+2.1%).. Reductions in LDL-C and changes in other lipids were not significantly different in patients treated with pitavastatin 4 mg or atorvastatin 20 or 40 mg. Pitavastatin may, however, have a more favourable effect on the glycaemic status.

Pitavastatin is a novel, potent, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor. This study compared the long-term efficacy of pitavastatin and simvastatin in dyslipidemic patients at high risk of coronary heart disease.. A 44-week blinded extension study was conducted at 24 centers in five European countries for patients who had previously completed a 12-week randomized, double-blind core study in which they received pitavastatin 4 mg or simvastatin 40 mg once daily. Patients originally randomized to pitavastatin 4 mg continued at the same dose throughout the extension study (n = 121). In simvastatin-treated patients (n = 57), the dose was increased to 80 mg in five patients who had not attained the National Cholesterol Education Program (NCEP) target for low-density lipoprotein cholesterol (LDL-C) during the core study. Primary endpoints were the proportion of patients attaining the NCEP and European Atherosclerosis Society (EAS) LDL-C targets, and the NCEP target for non-high-density lipoprotein cholesterol (non-HDL-C) at weeks 16 and 44.. Of the 178 patients who entered the extension study, 156 patients (109 in the pitavastatin group, 47 in the simvastatin groups) completed the 44-week treatment period. At week 44, NCEP and EAS targets were attained by 81.7% and 84.2%, respectively, of pitavastatin-treated patients, and 75.4% and 73.7%, respectively, of simvastatin-treated patients. NCEP targets for non-HDL-C were achieved by 79.2% of pitavastatin-treated patients and 70.2% of simvastatin-treated patients. Both treatments were generally well tolerated, but pitavastatin 4 mg was associated with a numerically lower incidence of discontinuations due to treatment-emergent adverse events (5.8% vs. 10.5% of patients) and a lower rate of myalgia (4.1% vs. 12.3%) compared with simvastatin 40-80 mg.. Pitavastatin 4 mg provides long-term efficacy similar to that of simvastatin 40-80 mg. Further studies should ascertain whether trends suggesting that pitavastatin may exhibit a more favorable long-term tolerability profile are statistically significant.

Despite the proven efficacy of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) in lowering total and low-density lipoprotein cholesterol (LDL-C), many patients do not reach recommended lipid targets. This study compared pitavastatin, a new and highly effective statin, and simvastatin in patients at high risk of coronary heart disease (CHD). The primary objective was to demonstrate noninferiority of pitavastatin to simvastatin.. The study was a phase 3, randomized, double-blind, double-dummy, parallel-group, active-controlled study conducted at 37 centers in five European countries. Following a dietary run-in period of 6-8 weeks, patients with primary hypercholesterolemia or combined dyslipidemia and at least two CHD risk factors were randomized 2:1 to receive pitavastatin 4 mg or simvastatin 40 mg once daily for 12 weeks. The primary efficacy variable was the change in LDL-C from baseline.. In total, 355 patients were randomized, 236 to pitavastatin and 119 to simvastatin; 330 patients (223 and 107, respectively) completed the study. In the pitavastatin group, mean (± SD) reduction in LDL-C concentrations from baseline was -44.0 ± 12.8% compared with -43.8 ± 14.4% in the simvastatin group. The adjusted mean treatment difference (simvastatin--pitavastatin) was 0.31% (95% confidence interval -2.47, 3.09; P = 0.829), which was within the predefined noninferiority range. More than 80% of patients in each group reached recommended LDL-C targets. Pitavastatin provided a greater increase in high-density lipoprotein cholesterol (HDL-C; 6.8% vs. 4.5%; P = 0.083) and a significantly greater decrease in triglycerides (-19.8% vs. -14.8%; P = 0.044) than simvastatin. Both treatments were well tolerated.. Pitavastatin 4 mg is as effective as simvastatin 40 mg in lowering LDL-C in dyslipidemic patients at high risk of CHD, with additional effects on HDL-C and triglycerides. Therefore, pitavastatin may be appropriate for the management of dyslipidemic patients at high cardiovascular risk.

Since co-administration of ezetimibe, a specific inhibitor of cholesterol absorption into the intestine, has been shown to augment lipid-lowering effects of statins, ezetimibe plus statins is a novel therapeutic strategy for the treatment of dyslipidemia in high-risk patients. Statins have been shown to ameliorate renal function and reduce proteinuria in patients with chronic kidney disease (CKD). However, effects of co-administration of ezetimibe with statins on renal damage and dysfunction in CKD patients remain unknown. In this study, we examined whether co-administration of ezetimibe with pitavastatin could augment renoprotective properties of pitavastatin in non-diabetic CKD patients with dyslipidemia. Total cholesterol, LDL-cholesterol and triglycerides levels were reduced more by co-administration of ezetimibe (10mg/day) with pitavastatin (2mg/day) (n=10) than by pitavastatin alone (n=10). In addition, ezetimibe plus pitavastatin treatment produced significant incremental reduction in proteinuria related to pitavastatin therapy alone. In univariate analyses, proteinuria was correlated with plasma levels of total cholesterol, LDL-cholesterol, triglycerides, HDL-cholesterol (inversely), asymmetric dimethylarginine, an endogenous nitric oxide synthase inhibitor, and urinary excretion levels of L-fatty acid binding protein (L-FABP), a marker of tubular injury and 8-hydroxydeoxyguanosine (8-OHdG), an oxidative stress marker. Multiple stepwise regression analysis revealed that LDL-cholesterol (p<0.001) and urinary excretion levels of L-FABP (p=0.001) and 8-OHdG (p<0.001) were independently related to proteinuria (R(2)=0.969). Our present study demonstrated for the first time that co-administration of ezetimibe enhanced proteinuria-lowering effects of pitavastatin in non-diabetic CKD patients partly via a cholesterol-independent manner. Ezetimibe may have pleiotropic actions that could contribute to renoprotective properties of this lipid-lowering agent.

We have retrospectively investigated the effects of three strong statins, atorvastatin, pitavastatin, and rosuvastatin, on serum uric acid (SUA) levels. SUA levels after a few months of statin treatment were compared with those before treatment in 150 outpatients with dyslipidemia. In the atorvastatin (n = 62) and rosuvastatin (n = 45) groups, the SUA levels were reduced by 6.5% (p < 0.0001) and 3.6% (p = 0.03) respectively, but in the pitavastatin group (n = 43), the SUA level increased by 3.7% (p = 0.38). Because uric acid is considered a risk factor for cardiovascular disorders, atorvastatin or rosuvastatin treatment may be recommended when statins are used in patients at high risk for cardiovascular disorders complicated with hyperuricemia.

Because postprandial hypertriglyceridemia and hyperglycemia may promote atherosclerosis, the present study investigated the effects of a clinical dose of pitavastatin on endothelial function and blood rheology in patients with coronary artery disease (CAD) before and after eating a test meal.. The 16 patients with stable CAD and mild dyslipidemia and 6 age-matched healthy men as controls were recruited. In each group, forearm blood flow (FBF) was measured during postischemic reactive hyperemia and blood samples were taken before and 2 h after the test meal. Urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) was also measured. The patients were started on pitavastatin 2 mg/day. The tests were repeated after 6 months. Maximum FBF during hyperemia in the baseline fasting phase was significantly lower in CAD patients than in control subjects (P=0.040). Fasting and postprandial FBF during reactive hyperemia significantly improved after pitavastatin treatment (P<0.05 vs baseline data for each phase) associated with reduced urine 8-OHdG, increased plasma adiponectin and improved lipid profile. No significant differences in baseline rheological parameters were seen between controls and CAD patients.. Pitavastatin significantly improved fasting and postprandial dyslipidemia and endothelial dysfunction in CAD patients, partly via reducing oxidative stress and increasing plasma adiponectin, although rheological parameters remained unchanged.

The primary objective of this study was to demonstrate equivalence of pitavastatin compared with simvastatin in the reduction of low-density lipoprotein cholesterol (LDL-C) levels in patients with primary hypercholesterolaemia or combined dyslipidaemia. Secondary objectives included achievement of National Cholesterol Education Program Adult Treatment Panel (NECP) and European Atherosclerosis Society (EAS) LDL-C goals, comparison of other lipid parameters, and assessment of safety and tolerability of the two statins.. A prospective, randomised, active-controlled double-blind, double-dummy, 12-week therapy trial was conducted in 857 patients with either primary hypercholesterolaemia or combined dyslipidaemia. The trial was designed to demonstrate the equivalence (non-inferiority of presumed equipotent doses) of pitavastatin compared with simvastatin. Patients were randomised to one of four groups: pitavastatin 2 mg/day, pitavastatin 4 mg/day, simvastatin 20 mg/day or simvastatin 40 mg/day. The main study limitation was restriction of the study population to those eligible for administration of simvastatin.. This clinical trial has been registered at www.clinicaltrials.gov NCT# NCT00309777.. Pitavastatin 2 mg showed significantly better reductions of LDL-C (p = 0.014), non-high-density lipoprotein cholesterol (non-HDL-C) (p = 0.021) and total cholesterol (TC) (p = 0.041) compared with simvastatin 20 mg and led to more patients achieving the EAS LDL-C treatment target. Reduction of LDL-C in the pitavastatin 2 mg group was 39% compared with 35% in the simvastatin 20 mg group. Pitavastatin 4 mg showed similar effects on all lipid parameters to simvastatin 40 mg. The reductions in LDL-C were 44% and 43%, respectively. The safety profiles of pitavastatin and simvastatin were similar at the two dose levels. Pitavastatin was considered superior to simvastatin in terms of percent reduction of LDL-C in the lower dose group comparison and proved to be equivalent to simvastatin in percent reduction of LDL-C in the higher-dose group.. As compared with simvastatin, an established first-line lipid-lowering agent, pitavastatin is an efficacious treatment choice in patients with primary hypercholesterolaemia or combined dyslipidaemia.

We aim to investigate the efficacy and safety of pitavastatin 4 mg in a population of people living in the United Arab Emirates (UAE).. Pitavastatin is a member of the HMG-CoA reductase inhibitors family which was approved for use in adult subjects with primary hyperlipidemia or mixed dyslipidemia. To date, no published studies have assessed the efficacy and safety of pitavastatin in the United Arab Emirates.. The main objective of the current study was to investigate the efficacy and safety of pitavastatin in subjects with dyslipidemia for the primary prevention of cardiovascular diseases based on total cardiovascular risk.. This was a multicentre (four private hospitals) prospective cohort study to analyze data on the use of pitavastatin for dyslipidemia in adult outpatients in Abu Dhabi and Dubai, United Arab Emirates. We have followed up the clinical profiles of subjects in four hospitals for six-weeks during the period from June 2015 to June 2017. Efficacy was based on the evaluation of the mean (± standard deviation) change in low-density lipoprotein cholesterol between baseline and week six after the initiation of pitavastatin therapy. Safety was reported with respect to the incidence of adverse events occurring with the use of pitavastatin and the development of new-onset diabetes.. A total of 400 subjects who were receiving pitavastatin 4 mg were included. The mean age of subjects was 50.7 ±10.8 years; of these, 79.0% were males. At the baseline, the mean level of total cholesterol was 185.4 ±41.5 mg/dL, low density lipoprotein was 154.9 ±48.55 mg/dL, high- -density lipoprotein cholesterol was 40.5 ±11.23 mg/dL and fasting blood glucose was 115.0 (±16.63) mg/dl. At the end of six weeks, low density lipoprotein levels significantly decreased to 112.09 ±41.90 mg/dl (standard mean difference (SMD) (-42.8%), 95% CI: -42.88 [-49.17 to -36.58] mg/dl, P <0.001), while high density lipoprotein levels improved (SMD, 95% CI: 1.77% [0.25 to 3.28] mg/dl, P <0.022). There were 55 subjects (13.7%) who reported various adverse events such as myalgia (7.5%), sleep disorders (2.5%), and myopathy (2.2%). Furthermore, 4 (1.0%) have had developed new-onset diabetes post-six-weeks of initiation of pitavastatin therapy.. Pitavastatin 4 mg showed robust efficacy in reducing LDL-C levels and improving HDL-C levels in subjects with dyslipidemia. The use of pitavastatin was associated with a low discontinuation rate, fewer adverse events, and very limited cases of new-onset diabetes.

Myopathy is possibly the most clinically relevant statin-induced side effect.. We report a case of a 63-year-old healthy male with mixed dyslipidemia. He developed bilateral myalgia of the forearms with fluvastatin 40 mg/day, pravastatin 20 mg/day, and combination of atorvastatin 10 mg and ezetimibe 10 mg/day. The only hypolipidemic treatment that was tolerable was the combination of pitavastatin 1 mg and ezetimibe 10 mg/day.. Pitavastatin demonstrated less potential for the development of myalgia compared to the so far considered most tolerable statins (i.e., fluvastatin and pravastatin). All the tested statins were used at the lowest approved dose for clinical use.. The combination of pitavastatin 1 mg and ezetimibe appears to be a promising treatment choice for individuals who are intolerant to statin therapy due to muscle complaints.

Statin therapy reduces the risk of cardiovascular events across a broad spectrum of patients; however, it increases the risk of new-onset diabetes (NOD). Although the highest dose pitavastatin is considered to not be associated with NOD, there are limited data regarding the impact of long-term highest dose pitavastatin use on the development of NOD in patients at high risk of developing diabetes. Therefore, we prospectively compared the differences in the development of NOD between the lowest and the highest dose of pitavastatin in patients at high risk of developing diabetes during a 3-year follow-up.. This post hoc analysis of a prospective, single-blinded, randomized study compared the risk of NOD between the highest dose of pitavastatin (4 mg) and the lowest dose of pitavastatin (1 mg) over a 3-year follow-up in patients with acute coronary syndrome. Among 1044 patients of the original study, 667 patients at high risk of developing type 2 diabetes mellitus were in the subgroup analysis. The primary endpoint was a comparison of the differences in the cumulative incidence of NOD in the pitavastatin 1 mg and 4 mg groups during a 3-year follow-up.. With propensity score matching, there were no significant differences in baseline demographic characteristics between the 2 groups. Incidence of NOD was similar between the pitavastatin 1 mg and 4 mg groups [12 of 289 patients (4.2%) and 8 of 289 patients (2.8%), respectively; p = 0.36]. In a prespecified analysis, there were no significant differences in NOD events according to sex, age, diagnosis, body mass index, glucose intolerance, or dyslipidemia.. Administration of highest-dose pitavastatin did not increase the risk of NOD in patients at high risk of developing diabetes during the 3-year follow-up. Moreover, various risk factors for NOD such as metabolic syndrome components, glucose intolerance, dyslipidemia, obesity, or hypertension did not affect the development of NOD during pitavastatin administration. Thus, the highest dose pitavastatin can be safely used in patients with metabolic syndrome who are at high risk of developing diabetes. Trial registration Clinical Trial registration information.

We aimed to examine the effect of serum sitosterol, a cholesterol absorption marker, on clinical outcomes in acute coronary syndrome patients with dyslipidaemia.. This is a sub-analysis of the HIJ-PROPER trial that assesses the effect of aggressive low-density lipoprotein cholesterol (LDL-C) lowering treatment with pitavastatin + ezetimibe in 1734 acute coronary syndrome (ACS) patients with dyslipidaemia. Patients were divided into two groups based on sitosterol level at enrolment (cut-off value was 2.2 μg/mL; a median of baseline sitosterol level), and clinical outcomes were examined.. The mean LDL-C level after 3 years in the low sitosterol group was 84.8 ± 20.1 mg/dL with pitavastatin-monotherapy and 64.6 ± 20.3 mg/dL with pitavastatin + ezetimibe, while corresponding values in the high sitosterol group were 91.0 ± 22.9 mg/dL and 71.1 ± 23.3 mg/dL, respectively. In the high sitosterol group, the Kaplan-Meier event rate for the primary endpoint at 3 years was 26.0% in the pitavastatin + ezetimibe group, as compared with 34.3% in the pitavastatin-monotherapy group (hazard ratio, 0.71; 95% confidence interval, 0.56-0.91; p = 0.006, p-value for interaction = 0.010). However, in the low sitosterol group, there was no significant reduction of the primary endpoint by pitavastatin + ezetimibe therapy.. Aggressive lipid-lowering treatment with ezetimibe had a positive effect on clinical outcomes in the high sitosterol subset of ACS patients with dyslipidaemia, but not in the low sitosterol subset. This effect was independent of LDL-C reduction and suggests that sitosterol measurement on admission in ACS patients might contribute to a "personalised" lipid-lowering approach.

Managing dyslipidaemia is central to the management of cardiovascular disease. Statins are the cornerstone of cardiovascular prevention for general population, and in patients with type 2 diabetes mellitus. However, statin therapy predisposes to type 2 diabetes, particularly in patients with predisposition to this condition. Some statins have been associated with increases in blood glucose in patients, and others have shown to have neutral effects, varying from one another their glucose or diabetogenic capacity. Pitavastatin is a new member of the statin class. And pitavastatin has a number of pleiotropic effects that can reduce inflammation and lipid oxidation, improve endothelial function, reduce the metabolic changes associated with adiposity, and improve glucose metabolism and renal function.

Angiotensin II-receptor blockers (ARBs), similar to HMG-CoA reductase inhibitors (statins), could improve lipid metabolism abnormalities. There might be some cross-talking pathways between statins and ARBs to produce additive beneficial effects on lipid metabolism in dyslipidemia. However, few studies investigate the effects of ARBs on the therapeutic efficacy of statins in dyslipidemia. The present study was designed to systematically evaluate the effects of telmisartan on the therapeutic efficacy of pitavastatin on lowering lipid level and reducing fat deposition by employing a dyslipidemia model, guinea pigs. 48 Male guinea pigs fed with high-fat diet were randomly grouped and treated with vehicle, telmisartan, pitavastatin or telmisartan/pitavastatin combinations. After treatment for eight weeks, telmisartan could significantly enhance the therapeutic efficacy of pitavastatin by extremely reducing body weight gain, weight of adipose tissue and adipocyte size. However, telmisartan/pitavastatin combinations could not further improve lipid levels on the basis of pitavastain, though single telmisartan markedly decreased triglyceride (TG) and slightly increased high density lipoprotein cholesterol (HDL-C). Moreover, telmisartan/pitavastatin combinations significantly upregulated the gene expression level of peroxisome proliferator-activated receptor (PPAR)-δ, but no effects on the expression of PPAR-α/γ, leptin and adiponectin compared to monotherapy. Taken together, our studies provided new evidences that telmisartan has an additive beneficial influence on decreasing fat deposition and weight gain through PPAR-δ pathway but cannot enhance the therapeutic efficacy of pitavastatin on lowering lipid levels. The combinational administration of telmisartan and pitavastatin could be a potential therapeutic strategy for dyslipidemia related obesity and worthy of further investigation in obese animal models.

Intensive as compared to mild statin therapy has been proven to be superior in improving cardiovascular outcome, whereas the effects of intensive statin therapy on inflammation and lipoprotein biomarkers are not well defined.. This study assigned essential hypertensive patients with dyslipidemia to 6 months administration of mild (1 mg/day, n = 34) or intensive pitavastatin therapy (4 mg/day, n = 29), and various lipid and inflammation biomarkers were measured at baseline, and 3 and 6 months after the start of treatment.. Both pitavastatin doses were well tolerated, and there were no serious treatment-related adverse events. After 6 months, significant improvements in total cholesterol, triglycerides, low-density lipoprotein (LDL-) cholesterol, LDL/high-density lipoprotein cholesterol (LDL/HDL), apolipoproteins B, C-II, and E, apolipoprotein-B/apolipoprotein-A-I (Apo B/Apo A-I), and malondialdehyde (MDA-) LDL were observed in both groups. Compared with the mild pitavastatin group, the intensive pitavastatin therapy showed significantly greater decreases in C reactive protein (F = 3.76, p<0.05), total cholesterol (F = 10.65), LDL-cholesterol (F = 23.37), LDL/HDL (F = 12.34), apolipoproteins B (F = 19.07) and E (F = 6.49), Apo B/Apo A-I (F = 13.26), and MDA-LDL (F = 5.76) (p<0.01, respectively).. Intensive pitavastatin therapy may have a more favorable effect not only in decreasing LDL-cholesterol but also in pleiotropic benefits in terms of improvement of apolipoproteins, inflammation, or oxidation.

Although statins increase the plasma concentration of high-density lipoprotein cholesterol (HDL-C), it has not been elucidated whether the increased HDL particles possess normal antiatherosclerotic properties. Pitavastatin functions to increase the plasma HDL-C level and decrease the lowdensity lipoprotein cholesterol (LDL-C) level. In the present study, we sought to examine the qualitative changes in HDL during pitavastatin treatment.. A total of 30 patients with dyslipidemia were treated with 2 mg of pitavastatin for four weeks. The cholesterol efflux capacity and activities of the antioxidative enzymes paraoxonase-1 (PON-1) and platelet-activating factor acetylhydrolase (PAF-AH) were evaluated using polyethethylene glycol-treated HDL fractions before and after pitavastatin treatment.. Pitavastatin treatment decreased the serum LDL-C level by 39% and increased the serum HDL-C level by 9% (p＜0.05). In addition, pitavastatin increased the phospholipid content of HDL by 7.8% (p＜0.05). The pitavastatin-induced increase in the HDL-C level coincided with an increase in the cholesterol efflux capacity of the isolated HDL fraction of 8.6% (p＜0.05). The post-pitavastatin treatment activity of HDL-associated PON-1 (paraoxonase and arylesterase) was increased by 9% (p＜0.05) and 11% (p＜0.05), respectively, while the HDL-associated PAF-AH activity was not affected by pitavastatin.. In addition to its LDL-C-lowering effects, pitavastatin elevates the HDL-C level and enhances the cholesterol efflux capacity and antioxidative properties of HDL. Pitavastatin therefore increases the amount of functional HDL without attenuating HDL quality.

The aim of this prospective study was to determine whether statin therapy (pitavastatin) has a beneficial effect on the prevention of new-onset atrial fibrillation (AF) in elderly patients with hypertension (HTN) and to evaluate the relationships among statin treatment, the development of AF, and left atrial (LA) and ventricular (LV) structure and function.. We enrolled eligible elderly patients (≥65 years old) with HTN and LV hypertrophy until the number of patients reached 110 in both groups. The 110 patients with HTN who needed statin therapy (HTN with statin group) were started on pitavastatin (1-2 mg/day), and both groups continued with appropriate medication for HTN. LV and LA structure and function were examined by conventional and speckle-tracking echocardiography at baseline and after 1 year. LA volume and function in the HTN with statin group improved more than in the HTN without statin group. There was a significant difference in survival free of new-onset AF in the patients with and without statin therapy during the 2-year follow-up (hazard ratio: 0.32, P=0.027).. Pitavastatin had a beneficial effect on LV diastolic function and LA structure and function in elderly patients with HTN. Pitavastatin treatment may be associated with a lower incidence of new-onset AF.

Obesity and related metabolic abnormalities, including inflammation and lipid accumulation in the liver, play a role in liver carcinogenesis. Adipocytokine imbalances, such as decreased serum adiponectin levels, are also involved in obesity-related liver tumorigenesis. In the present study, we examined the effects of pitavastatin - a drug used for the treatment of hyperlipidemia - on the development of diethylnitrosamine (DEN)-induced liver preneoplastic lesions in C57BL/KsJ-db/db (db/db) obese mice.. Male db/db mice were administered tap water containing 40 ppm DEN for 2 weeks and were subsequently fed a diet containing 1 ppm or 10 ppm pitavastatin for 14 weeks.. At sacrifice, feeding with 10 ppm pitavastatin significantly inhibited the development of hepatic premalignant lesions, foci of cellular alteration, as compared to that in the untreated group by inducing apoptosis, but inhibiting cell proliferation. Pitavastatin improved liver steatosis and activated the AMPK-α protein in the liver. It also decreased free fatty acid and aminotransferases levels, while increasing adiponectin levels in the serum. The serum levels of tumor necrosis factor (TNF)-α and the expression of TNF-α and interleukin-6 mRNAs in the liver were decreased by pitavastatin treatment, suggesting attenuation of the chronic inflammation induced by excess fat deposition.. Pitavastatin is effective in inhibiting the early phase of obesity-related liver tumorigenesis and, therefore, may be useful in the chemoprevention of liver cancer in obese individuals.

The primary objective was to assess the safety and tolerability of pitavastatin 4mg once daily during 52 weeks treatment. The secondary objectives were to assess the effect on lipid and lipoprotein fractions and ratios, and LDL-C target attainment.. Patients with primary hypercholesterolemia or combined dyslipidemia who had previously received pitavastatin, atorvastatin or simvastatin for 12 weeks during double-blind phase III studies received open-label pitavastatin 4mg once daily for up to 52 weeks.. Investigators at 72 sites enrolled 1353 patients who received at least one dose of pitavastatin 4mg; 155 (11.5%) patients discontinued treatment during the 52-week follow up. The proportion of patients achieving NCEP and EAS LDL-C targets at week 52 was 74.0% and 73.5% respectively. The reduction in LDL-C levels seen during the double-blind studies was sustained, while HDL-C levels rose continually during follow up, ultimately increasing by 14.3% over the initial baseline. Changes in other efficacy parameters (triglycerides, total cholesterol, non-HDL-C, Apo-A1 and Apo-B, high sensitivity C-reactive protein, oxidised LDL) and ratios (total cholesterol: HDL-C, non-HDL-C:HDL-C and Apo-B:Apo-A1) were sustained during 52-weeks treatment compared with the end of the double-blind studies. Pitavastatin was well tolerated: 4.1% of patients withdrew from the study due to treatment emergent adverse events (TEAEs) and none of the serious adverse events were considered treatment-related. No clinically significant abnormalities were associated with pitavastatin in routine laboratory variables, urinalysis, vital signs or 12-lead ECG. There were no reports of myopathy, myositis or rhabdomyolysis. The most common TEAEs were: increased creatine phosphokinase (5.8%), nasopharyngitis (5.4%) and myalgia (4.1%).. Pitavastatin 4mg once daily was effective and well tolerated during 52-weeks treatment in patients with primary hypercholesterolemia or combined dyslipidemia. Around three-quarters of patients achieved NCEP and EAS LDL-C targets at week 52, HDL-C levels rose continually during follow up, while changes in other efficacy parameters were sustained over the year-long study.

Prevention of cardiovascular complications in obese patients frequently includes statin administration for coexisting dyslipidemia. Herein, we investigated the impacts of pitavastatin at clinically relevant doses on adipose dysfunction and insulin resistance.. We treated 3T3-L1 preadipocytes with 10-100 ng/ml pitavastatin from initiation of differentiation (Day 0) to Day 8 (differentiation/maturation phase) or from Day 8 to Day 16 (post-maturation phase). Subsequently, we administered pitavastatin (6.2mg/day/kg) to 7-week-old female KKAy mice for 6 weeks; untreated KKAy mice served as obese controls.. Pitavastatin impaired neither lipogenesis nor adiponectin expression during the differentiation/maturation phase. During the post-maturation phase, pitavastatin prevented excessive triglyceride accumulation, which was associated with attenuated glucose transporter-4 expression, and dose-dependently upregulated hormone-sensitive lipase expression. Decrements in the adiponectin/plasminogen activator-1 ratio were also dose-dependently inhibited. In KKAy mice, Coulter counter analyses revealed that pitavastatin treatment significantly decreased (by 16.8%) the frequency of hypertrophic adipocytes (>150 microm in diameter) in parametrial adipose pads, of which total weight remained unaltered. Correspondingly, plasma adiponectin was significantly higher in pitavastatin-treated KKAy mice than in the untreated KKAy mice (12.5+/-3.8 microg/ml vs. 8.3+/-1.5 microg/ml, p<0.05). Moreover, the area under the time-glucose curve after intraperitoneal insulin was decreased by 16% in pitavastatin-treated KKAy mice (p<0.05 vs. untreated controls).. Pitavastatin did not impair differentiation/maturation of preadipocytes and prevented their deterioration with hypertrophy after maturation at clinical concentrations in vitro. These effects likely contributed to improved insulin sensitivity, in an obese model, via prevention of adipocyte hypertrophy and adipocytokine dysregulation.

Vascular endothelial dysfunction has been demonstrated in obesity, but the molecular basis for this link has not been clarified. We examined the role of free fatty acids (FFA) on vascular reactivity in the obese fa/fa Zucker diabetic fatty (ZDF) rat. Addition of acetylcholine produced a dose-dependent relaxation in aortic rings of ZDF and lean +/+ rats, but the ED(50) value was higher in ZDF (-6.80 +/- 0.05 vs. -7.11 +/- 0.05 log(10) mol/liter, P = 0.033). A 2-wk treatment with a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, pitavastatin (3 mg/kg/d) or a reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase inhibitor, apocynin (5 mmol/liter in drinking water), improved the response in ZDF (ED(50), -7.16 +/- 0.03 and -7.14 +/- 0.05 log(10) mol/liter, P = 0.008 and P = 0.015 vs. vehicle, respectively). Vasodilator response to sodium nitroprusside was identical between ZDF and +/+ rats. Vascular reactive oxygen species (ROS) levels and NADPH oxidase activity in aorta were increased in ZDF rats but were decreased by pitavastatin. In in vitro cell culture, intracellular ROS signal and NADPH oxidase subunit mRNA were increased by palmitate, but this palmitate-induced ROS production was inhibited by NADPH oxidase inhibitor or pitavastatin. In conclusion, FFA-induced NADPH oxidase subunit overexpression and ROS production could be involved in the endothelial dysfunction seen in obese ZDF rats, and this could be protected by pitavastatin or NADPH oxidase inhibitors.
