olanzapine and Hypertension

Schizophrenia, a serious psychiatric disorder, is among the top 10 global causes of disability and affects nearly 1% of the world population. Antipsychotics constitute the best treatment for patients with schizophrenia, however, this treatment class carries a high risk of metabolic syndrome, including lipid abnormalities. Indeed, the risk of metabolic syndrome would be increased in the population with schizophrenia compared to the general population. The objective is to summarize the prevalence, the mechanisms, and the potential treatments of antipsychotic-induced metabolic syndrome. This is a narrative review of the literature. We searched the electronic database Medline, accessed through PubMed, to find studies that investigated the prevalence and treatments of metabolic syndrome in the adult population using antipsychotics. The prevalence of metabolic syndrome in patients treated with antipsychotics ranges from 37% to 63%. Antipsychotic iatrogenic effects include weight gain/increased waist circumference, dyslipidemia, insulin resistance/type 2 diabetes, and hypertension. Clozapine and olanzapine are reported to precipitate the onset of metabolic syndrome features. In patients with metabolic syndrome, an antipsychotic with less metabolic side effects such as lurasidone, lumateperone, ziprasidone, and aripiprazole should be prioritized. Unlike medications, aerobic exercise and dietetic counseling were found to be efficient as the nonpharmacologic treatment of antipsychotic-induced metabolic syndrome. Few pharmacological treatments were proven effective against weight gain in this patient population. The risk of metabolic syndrome induced by antipsychotics should be early recognized and closely monitored. Primary and secondary prevention of metabolic syndrome or onset of its feature might help reduce the risk of death for patients using antipsychotics.

Weight gain and adverse cardiometabolic effects often limit the clinical utility of olanzapine. In ENLIGHTEN-2, combining olanzapine with the opioid receptor antagonist samidorphan (OLZ/SAM) mitigated olanzapine-associated weight gain. These analyses tested the hypothesis that OLZ/SAM would be associated with reduced adverse cardiometabolic effects compared with olanzapine.. This phase 3 double-blind study randomized adults with schizophrenia to OLZ/SAM or olanzapine for 24 weeks. Post hoc analyses assessed changes from baseline to week 24 in cardiometabolic risk parameters, including body mass index (BMI), risk of developing obesity (BMI ≥30 kg/m2) or metabolic syndrome, waist circumference, along with mean and potentially clinically significant changes in blood pressure, glucose, and lipids.. After 24 weeks' treatment, compared with olanzapine, OLZ/SAM was associated with smaller least-squares mean (LSM) changes from baseline in systolic blood pressure (LSM difference, -2.63 mm Hg; 95% CI: -4.78, -0.47), diastolic blood pressure (LSM difference, -0.75 mm Hg; 95% CI: -2.31, 0.80), and BMI (LSM difference, -0.65 kg/m2; 95% CI: -1.01, -0.28). OLZ/SAM treatment was also associated with reduced risk of shifting from normal blood pressure to stage 1/2 hypertension (odds ratio [OR], 0.48; 95% CI: 0.24, 0.96), becoming obese (OR, 0.52; 95% CI: 0.32, 0.82), and developing metabolic syndrome (OR, 0.55; 95% CI: 0.31, 0.99) compared with olanzapine. No treatment group differences were noted for risk of hyperglycemia or hyperlipidemia.. OLZ/SAM treatment was associated with lower risk of worsening cardiometabolic risk factors related to obesity, hypertension, and metabolic syndrome relative to olanzapine.

There is limited, poorly characterized information about adverse events occurring during maintenance treatment of bipolar disorder. We aimed to determine adverse event rates during treatment with lithium, valproate, olanzapine, and quetiapine.. We conducted a propensity score adjusted cohort study using nationally representative United Kingdom electronic health records from January 1, 1995, until December 31, 2013. We included patients who had a diagnosis of bipolar disorder and were prescribed lithium (n = 2148), valproate (n = 1670), olanzapine (n = 1477), or quetiapine (n = 1376) as maintenance mood stabilizer treatment. Adverse outcomes were chronic kidney disease, thyroid disease, hypercalcemia, weight gain, hypertension, type 2 diabetes mellitus, cardiovascular disease, and hepatotoxicity. The propensity score included important demographic, physical health, and mental health predictors of drug treatment allocation. The median duration of drug treatment was 1.48 y (interquartile range 0.64-3.43). Compared to patients prescribed lithium, those taking valproate, olanzapine, and quetiapine had reduced rates of chronic kidney disease stage 3 or more severe, following adjustment for propensity score, age, and calendar year, and accounting for clustering by primary care practice (valproate hazard ratio [HR] 0.56; 95% confidence interval [CI] 0.45-0.69; p < 0.001, olanzapine HR 0.57; 95% CI 0.45-0.71; p < 0.001, quetiapine HR 0.62; 95% CI 0.47-0.80; p < 0.001). Hypothyroidism was reduced in those taking valproate (HR 0.60; 95% CI 0.40-0.89; p = 0.012) and olanzapine (HR 0.48; 95% CI 0.29-0.77; p = 0.003), compared to those taking lithium. Rates of new onset hyperthyroidism (valproate HR 0.24; 95% CI 0.09-0.61; p = 0.003, olanzapine HR 0.31; 95% CI 0.13-0.73; p = 0.007) and hypercalcemia (valproate HR 0.25; 95% CI 0.10-0.60; p = 0.002, olanzapine HR 0.32; 95% CI 0.14-0.76; p = 0.008, quetiapine HR 0.23; 95% CI 0.07-0.73; p = 0.013) were also reduced relative to lithium. However, rates of greater than 15% weight gain on valproate, olanzapine, and quetiapine were higher (valproate HR 1.62; 95% CI 1.31-2.01; p < 0.001, olanzapine HR 1.84; 95% CI 1.47-2.30; p < 0.001, quetiapine HR 1.67; 95% CI 1.24-2.20; p < 0.001) than in individuals prescribed lithium, as were rates of hypertension in the olanzapine treated group (HR 1.41, 95% CI 1.06-1.87; p = 0.017). We found no significant difference in rates of chronic kidney disease stage 4 or more severe, type 2 diabetes mellitus, cardiovascular disease, or hepatotoxicity. Despite estimates being robust following sensitivity analyses, limitations include the potential for residual confounding and ascertainment bias and an inability to examine dosage effects.. Lithium use is associated with more renal and endocrine adverse events but less weight gain than commonly used alternative mood stabilizers. Risks need to be offset with the effectiveness and anti-suicidal benefits of lithium and the potential metabolic side effects of alternative treatment options.

This study aims to explore and analyze the condition of concurrent diseases and medicine use of traditional Chinese medicine (TCM) and western medicine among the patients with insomnia. One thousand and sxity seven cases of data from 20 national hospitals' hospital information system (HIS) databases were collected. The frequent concurrent diseases included hypertension (26.9%), brain blood supply insufficiency (24.93%), cerebral infarction (19.49%), blood lipoprotein disturbance (15.28%), coronary heart disease (14.15%), headache (10.68%), chronic gastritis (8.81%), type 2 diabetes mellitus (7.87%), depressive disorder (7.4%) and anxiety disorder (6.65%). The 10 most frequently-used western drugs included alprazolam (35.99%), aspirin (25.4%), olanzapine (24.18%), cinepazide (23.06%), flupentixol & melitracen (18.74%), zolpidem (18.37%), oxiracetam (15.65%), estazolam (15%), aniracetam (13.4%) and piracetam (13.31%). The 10 most frequently-used TCM included Shuxuening injection (16.4%), Shuxuetong injection (15.18%), extract of ginkgo biloba leaf (14.71%), gastrodin (12.46%), Dengzanxixin injection (11.34%), Xueshuantong (8.53%), Danhong injection (6.37%), compound liquorice tablet (5.81%), Sanqi Tongshu capsule (5.72%) and sowthistle-leaf ixeridium injection (5.34%). Among all combined uses, the most frequent western drug use was alprazolam and olanzapine, while combined use of hypnotic drug and Huoxuehuayu formula is the most frequent. This study concludes that the concurrent diseases mainly include cardio-cerebrovascular diseases, metabolic disorders and anxiety-depression disorders, with increasing tendency of diseases types by ages, especially for cardio-cerebrovascular diseases. The most frequently-used hypnotic is alprazolam in the insomnia patients, and it is worth being concerned about the off-label use of olanzapine as an antipsychotic for the treatment of insomnia However, due to the fact that all cases data are from the inpatients, these findings have some limitations.

Olanzapine is a second generation antipsychotic of thienobenzodiazepin group, which is used in the treatment of schizophrenia, bipolar disorder, and others, mainly psychiatric. Its multireceptor action (antagonism to dopaminergic D1, D2, D4, serotoninergic 5-HT2A, 5-HT2C, histaminergic H1, cholinergic M1-5, and a1--adrenergic receptors) results in multiple clinical symptoms in the course of acute poisoning.. Evaluation of incidence and intensity of clinical symptoms in patients with of acute olanzapine intoxication. The pathophysiological mechanisms of particular symptoms are also described.. 26 patients (mean age 37.7 +/- 15.3 years) hospitalized in 2005-2008 in toxicological centers in Krakow and Gdansk because of acute olanzapine poisoning (all patients had the toxic serum level of olanzapine above 100 ng/mL). The study group consisted of 11 men (29.3 +/- 8.5 years) and 13 women (44.9 +/- 16.4 years); 1 man and 1 woman were poisoned twice.. Prospective analysis (using descriptive statistics) of data taken from medical anamnesis and results of physical examination, considering the following ones: consciousness disturbances (Glasgow Coma Scale, Matthew's scale, qualitative disturbances), vital signs (arterial blood pressure, heart rate, breathing rate, temperature), neurological findings (muscular tension, tendon reflexes, extrapyramidal symptoms, pupils) and others (oral and bronchial secretion, Poisoning Severity Score).. The mean dose of ingested olanzapine in the study group was 352.5 +/- 220.0 mg, while the mean time since ingestion to hospital admission was 4.4 +/- 3.5 h. The half of the patients took other medicines together with olanzapine, and 23% consumed alcohol, as well. The following intensity of quantitative consciousness disturbances according to Matthew's scale were observed: grade 0 - 8%, I - 15%, II - 23%, III - 50%, and IV - 4%. The minimal and maximal values of blood pressure were: 102/63 +/- 16/14 and 163/ 97 +/- 27/18 mmHg, respectively; heart rate: 77 +/- 15 and 138 +/- 22 beats/min; temperature: 36.3 +/- 0.5 and 37.9 +/- 0.8 degrees C; breathing rate in non-intubated patients: 14 +/- 2 and 22 +/- 7 breaths/min. The mean duration of consciousness disturbances, endotracheal intubation and mechanical ventilation were: 44.9 +/- 31.3; 22.0 +/- 33.3 and 7.0 +/- 25.9 h, respectively. The study revealed tachycardia (85%), psychomotor agitation (81%), hypertension (73%), miosis (65%), and coma (54%) as the most common symptoms of poisoning. The hospitalization of poisoned patients lasted on average 5.7 +/- 3.6 days and the half of them were poisoned severely (PSS 3).. In the course of acute olanzapine poisoning: (1) the prevailing symptoms come from circulatory and central nervous systems; (2) some symptoms are mutually opposed, eg.: coma - psychomotor agitation, hypertension - hypotension, tachycardia - bradycardia, hyperthermia - hypothermia, miosis - mydriasis; (3) rarely consciousness disturbances may persist for up to 6 days after olanzapine overdose; (4) the course of poisoning can be severe, sometimes complicated, but fatal outcomes are rare.

A case of acute pancreatitis associated with lisinopril and olanzapine is described.. A 69-year-old woman came to the emergency department after four days of experiencing epigastric pressurelike pain that radiated to the left lower quadrant and worsened with ingestion of food. She had started lisinopril three months prior for treatment of hypertension and had been taking olanzapine regularly for bipolar disorder. Upon admission, she was afebrile and hemodynamically stable and exhibited tenderness of the epigastric region. Elevated pancreatic enzymes and abdominal computed tomography (CT) imaging findings confirmed the diagnosis of pancreatitis. Common causes of pancreatitis were ruled out, and it was determined that the recent combination of lisinopril and olanzapine was the likely cause. Food and liquids were withheld, and all oral medications were stopped at hospital admission. Her pain resolved completely after two days. She was discharged on hospital day 4, and all of her medications except lisinopril and olanzapine were resumed. During a follow-up visit with her primary care physician, she reported to be doing well and had no systemic complaints. Olanzapine was reinitiated at that time but was discontinued a month later by her psychiatrist, who was concerned about the development of recurrent symptoms of pancreatitis. Valsartan was prescribed to achieve optimal blood pressure control three weeks after discharge. A follow-up CT scan of the abdomen a month later found no residual pancreatic abnormalities.. The additive effect of two known pancreatitis-causing medications resulted in increased risk and subsequent acute pancreatitis in this patient.

Numerous reports have linked atypical antipsychotics, especially clozapine and olanzapine, to the development of cardiovascular risk factors. In this retrospective chart review study, we investigated the blood pressure changes in Korean schizophrenic inpatients treated with clozapine or olanzapine.. We reviewed the medical record of schizophrenic patients treated with clozapine or olanzapine for 8 weeks. A total of 167 patients were included in the study; 70 patients in clozapine group and 97 patients in olanzapine group. Systolic and diastolic blood pressures prior to medication and at post-treatment (8-week) were assessed, and changes in blood pressure were analyzed. The prevalence of hypertension at the time of study period was assessed and compared between the two groups.. There was a significant difference in hypertension prevalence in comparisons between the clozapine and olanzapine group. The systolic and diastolic blood pressures in the clozapine group were significantly increased after treatment, but systolic and diastolic blood pressures in olanzapine group did not change significantly.. Our findings suggest that clozapine treatment may be associated with increased blood pressure and higher prevalence of hypertension, which may have a significant impact on medical morbidity and mortality.

Adverse effects from medication vary with age. Weight gain with several psychotropics is well known in adults but less information is available related to extent and complications of psychotropic-induced weight gain in older psychiatric patients. We determined the relative incidence of 2 obesity-related conditions (diabetes and hypertension) in older psychiatric patients receiving antipsychotics, antidepressants, and mood stabilizers.. A population-based case-control study of all psychiatric patients aged 67 years or older in contact with either specialist services or primary care using administrative data from Nova Scotia.. We identified incident cases of diabetes (n = 608) and of hypertension (n = 1056), as well as an equal number of control subjects for each condition. Amitryptiline, selective serotonin reuptake inhibitors (SSRIs), and olanzapine were associated with an increased risk of presenting with hypertension 6 months after initial prescription. By contrast, conventional antipsychotics were associated with a reduced incidence of hypertension. Olanzapine was also significantly associated with diabetes after 6 months (OR adj = 2.58, 95% CI 1.12 to 5.92). The findings for SSRIs and olanzapine remained significant after adjusting for potential confounders such as sociodemographic characteristics, schizophrenia, beta blockers, thiazide diuretics, and corticosteroids.. Our results suggest that the association of psychotropics and 2 obesity-related conditions, hypertension and diabetes, applies to older psychiatric patients as well as younger populations. Within drug classes, there are drugs that have a greater association than others, and this may be a factor when choosing a specific agent.

Antipsychotic (AP) treatment, in particular with some second-generation drugs, is associated with weight gain and other metabolic side effects. However, the relationship between drug-induced weight gain and dyslipidemia is not well understood. We investigated how cardiometabolic risk factors were related to body mass during treatment with different APs under real-life conditions.. This cross-sectional naturalistic study included 242 subjects with severe mental disorders who were on monotherapy with olanzapine (OLZ) or clozapine (CLZ) (n = 80), monotherapy with other APs (n = 80), or unmedicated (n = 82). Groups were adjusted for age and compared for prevalence of the metabolic syndrome and its components. Groups were further adjusted for body mass and compared for mean values of blood pressure, lipids, and fasting glucose.. There was no significant intergroup difference in the prevalence of metabolic syndrome, obesity, hypertension, or hyperglycemia. Despite similar body mass index, OLZ/CLZ-treated subjects had significantly higher prevalence of dyslipidemia (high triglyceride and low HDL cholesterol levels) than unmedicated subjects. They also had higher mean values of triglycerides (P = 0.003) and lower mean values of HDL cholesterol (P < 0.001). Patients treated with other APs had intermediate values.. Intergroup differences in body mass index were minimal in this naturalistic setting, probably because of awareness of this treatment hazard among clinicians. However, independently of body mass, dyslipidemia was significantly associated with AP treatment, in particular with OLZ and CLZ. These findings indicate a primary effect of APs on lipid regulation, important in understanding their mechanism of action, and with clinical implications.

Metabolic syndrome is a strong determinant of new-onset diabetes and coronary heart disease in general populations. Given the higher prevalence of metabolic syndrome among mentally ill patients, the syndrome poses a greater health risk to this population. Atypical antipsychotic treatment may exacerbate this condition. We compared both the rate and incidence of metabolic syndrome among schizophrenia patients (DSM-IV criteria) treated with the atypical antipsychotics aripiprazole or olanzapine or placebo from 4 double-blind, randomized, controlled clinical trials.. Metabolic syndrome was defined according to the Third Adult Treatment Panel (ATP III) Guidelines as the presence on follow-up of 3 of the following abnormalities: waist circumference > 102 cm if male and > 88 cm if female, high density lipoprotein (HDL) < 40 mg/dL if male and < 50 mg/dL if female, diastolic blood pressure >or= 85 mm Hg or systolic blood pressure >or= 130 mm Hg, fasting triglycerides >or= 150 mg/dL, fasting plasma glucose >or= 110 mg/dL. Both the rate of metabolic syndrome and the person-time incidence were computed from the on-treatment follow-up.. In the placebo-controlled trials, the rate of metabolic syndrome was 25.8% among 155 placebo patients and 19.9% for 267 aripiprazole patients (p = .466 by stratified log rank). The incidence of metabolic syndrome was 14.3% for 91 placebo patients versus 5.3% for 151 aripiprazole patients (p < .001). In the active comparator trials, patients treated with olanzapine (N = 373) versus aripiprazole (N = 380) exhibited rates of 41.6% and 27.9%, respectively (p = .0002). Incidence rates were 27.4% for 212 olanzapine patients versus 15.7% for 198 aripiprazole patients (p = .0055).. Both the rate and incidence of clinically relevant metabolic syndrome differ according to the choice of antipsychotic agent. The association between metabolic syndrome and treatment warrants careful consideration in the choice of antipsychotic agents.
