troxerutin and Chronic-Disease

Troxerutin (TRX), a semi-synthetic bioflavonoid derived from rutin, has been reported to exert several pharmacological effects including antioxidant, anti-inflammatory, antihyperlipidemic, and nephroprotective. However, the related molecular details and its mechanisms remain poorly understood. In the present review, we presented evidences from the diversity in vitro and in vivo studies on the therapeutic potential of TRX against neurodegenerative, diabetes, cancer and cardiovascular diseases with the purpose to find molecular pathways related to the treatment efficacy. TRX has a beneficial role in many diseases through multiple mechanisms including, increasing antioxidant enzymes and reducing oxidative damage, decreasing in proapoptotic proteins (APAF-1, BAX, caspases-9 and-3) and increasing the antiapoptotic BCL-2, increasing the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and downregulating the nuclear factor κB (NFκ). TRX also reduces acetylcholinesterase activity and upregulates phosphoinositide 3- kinase/Akt signaling pathway in Alzheimer's disease models. Natural products such as TRX may develop numerous and intracellular pathways at several steps in the treatment of many diseases. Molecular mechanisms of action are revealing novel, possible combinational beneficial approaches to treat multiple pathological conditions.

Rutoside (rutin; quercetin rutinoside) is a glycoside found in various plant products, including apples, citrus fruits and cranberries. Hydroxyethylrutosides (HR) are semisynthetic derivatives sold as standardized products for the treatment of chronic venous insufficiency (CVI). Commercially available products include Relvène(®) (France), Venoruton(®) (Switzerland) and Paroven(®) (United Kingdom). However, the evidence for their efficacy is inconclusive. The aim of this systematic review was to evaluate the evidence of efficacy and tolerability of hydroxyethylrutosides for CVI.. We searched electronic databases such as the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and CINAHL, and publisher databases, conference proceedings and references lists for randomized controlled trials published in English and non-English languages. We also performed hand searches for additional trials. We included all trials that assessed the effectiveness of HR for CVI. Comparisons include HR (with or without compression bandaging) vs. placebo (with or without compression bandaging) or HR vs. compression bandaging alone. Two review authors independently selected studies, extracted data and assessed risks of bias in the included trials.. The search identified 1474 records. Only 15 trials involving 1643 participants met our inclusion criteria. A meta-analysis based on similar studies that compared HR with placebo showed that HR significantly reduced symptoms of pain (SMD -1·07, 95% CI -1·44 to -0·70), symptoms of heavy legs (OR 0·50; 95% CI 0·28-0·91) and cramps (SMD -1·07, 95% CI -1·45 to -0·69). No serious adverse effect due to HR was reported.. The findings showed that HR produced modest improvements in several symptoms of CVI. However, all the included trials were of limited quality, and therefore, better-quality trials are still required to draw firm conclusions on the usefulness of HR for CVI.

The aim of this article was first to review the complex pathophysiological mechanisms responsible for symptoms and signs of primary chronic venous disease (CVD) that allow the identification of targets for pharmacological treatment. The results of CVD treatment with venoactive drugs (VADs) were emphasised and presented in the form of recommendations. The last section raises key questions to be answered to improve protocols for good clinical trials and to draw up future guidelines on these agents.. The literature has been reviewed here using PubMed and Embase.. Venous hypertension appears to underlie all clinical manifestations of primary CVD. Inflammation is key in wall remodelling, valve failure and subsequent venous hypertension. Changes in the haemodynamics of veins are transmitted to the microcirculation, resulting in capillary alteration leading to oedema, skin changes and eventually venous ulceration. Venous symptoms may be the result of interplays between pro-inflammatory mediators and nerve fibres located in the venous wall. Therefore, venous inflammation constitutes a promising therapeutic target for pharmacological intervention, and some available VADs could attenuate various elements of venous inflammation. Based on recent studies, reviews and guidelines, tentative recommendations for the use of VADs were proposed and strong recommendations were given to two of them (micronised purified flavonoid fraction and oxerutins).. VADs should be accorded a better role in the management of CVD. However, larger and more definitive clinical trials are needed to improve the existing recommendations.

A range of surgical, endovenous, physical and medical treatments are available for patients with chronic venous disease. The aim of this review was to evaluate the evidence for pharmacological agents used for the treatment of chronic venous disease.. A literature search was performed using Pubmed, Embase, Cochrane and Google Scholar databases. The initial search terms 'varicose vein', 'venous ulcer', 'venous disease' and 'lipodermatosclerosis' were used to identify relevant clinical studies of pharmacotherapy in patients with chronic venous disease (C4-C6).. A huge range of naturally occurring and synthetic drugs have been studied in patients with chronic venous disease. For patients with C4 venous disease, micronized purified flavonoid fraction (MPFF), oxerutin, rutosides and calcium dobesilate may reduce venous symptoms and oedema. MPFF and pentoxifylline have been shown to improve venous ulcer healing when used in addition to multilayer compression bandaging. The clinical benefits of other medications remain unproven. Reliability of meta-analyses was limited by study heterogeneity, small sample sizes and lack of long-term follow-up.. In prospective randomized studies, MPFF (Daflon(®)), other flavonoid derivatives and pentoxifylline have demonstrated clinical benefits in patients with C4-C6 venous disease. Pharmacotherapy should be part of a range of treatment options in the modern management of patients with chronic venous disorders.

Varicose veins and the complications of venous disease are thought to affect over a quarter of the adult population and the management of these conditions are a major cause of health service expense. Advances in the understanding of venous pathophysiology have highlighted numerous potential targets for pharmacotherapy. This review considers the evidence for pharmacological agents used for the treatment of chronic venous disease. A literature search using Pubmed, Embase and Cinahl databases was performed. The initial search terms 'varicose vein', 'venous ulcer' and 'venous disease' were used with appropriate search limits to identify prospective studies of pharmacotherapy in venous disease. A wide range of venoactive and non-venoactive drugs have been studied in patients with venous disease. The use of micronized purified flavonoid fraction (Daflon) can reduce symptoms of pain, heaviness and oedema in patients with venous reflux and a recent meta-analysis concluded that Daflon improves healing in patients with venous ulceration treated with compression. Pentoxifylline may be a useful adjunct to compression therapy for patients with venous ulceration. Oxerutins and calcium dobesilate may be of benefit in reducing oedema and rutosides may help to relieve the symptoms of varicose veins in pregnancy. The clinical benefits of other medications remain unproven. Although numerous pharmacological agents have been proposed and studied, Daflon has demonstrated the greatest clinical benefits in patients with venous disease. Further research is needed to define the role of venoactive drugs in clinical care and improve our understanding of the pathophysiology of venous disease to help identify new therapeutic avenues.

Our current understanding of the pathophysiology of chronic venous disease (CVD) suggests that veno-active drugs (VAD) can provide effective symptom relief. Few studies have conducted head-to-head comparisons of VAD and placebo while also assessing objective measures (such as water plethysmography findings and tibiotarsal joint range of motion) and patient-reported quality of life outcomes.. To compare the effects of different VAD on limb volume reduction, tibiotarsal range of motion, and quality of life.. 136 patients with CVD (CEAP grades 2-5) were randomly allocated into four groups to receive micronized diosmin + hesperidin, aminaphthone, coumarin + troxerutin, or placebo (starch). Patients were administered a questionnaire consisting of a quality of life (QoL) measure designed specifically for persons with CVD, and underwent tibiotarsal joint angle measurement and water plethysmography of the lower extremity before and 30 days after pharmacological intervention. Assessors were blind to the treatment groups.. Nine patients dropped out of the trial. Data collected from the 127 remaining patients was considered for statistical analysis. There were no differences in tibiotarsal joint range of motion. Volume reductions ≥100 mL were more frequent in the diosmin + hesperidin group than in any other group. QoL scores were best in the aminaphthone group, and between-group differences were found on individual analysis of questionnaire items.. Use of VAD was associated with significant improvements in QoL as compared with placebo. VAD may be effective for providing symptom relief in patients with CVD.

Chronic venous insufficiency (CVI) is an important cause of discomfort and inability to work. Hydroxyethylrutosides (Venoruton); 0-[beta-hydroxyethyl]-rutosides) has been used for decades for the treatment of CVI. Studies have reported symptomatic relief and a decreased capillary filtration after the administration of the oral preparations. Calcium dobesilate is a synthetic venoactive drug acting on several levels. It inhibits capillary permeability; it has antioxidant properties; and it inhibits the synthesis of prostaglandins and thromboxanes, reducing platelet and erythrocyte aggregation, as well as blood viscosity. The aim of this study is to determine whether the combination of both drugs is more effective in decreasing patients' complaints.. One hundred and fifty patients with primary venous insufficiency were randomized into three groups: Group A receiving calcium dobesilate only, Group B receiving oxerutin only and Group C receiving both calcium dobesilate and oxerutin. Patients were evaluated with a questionnaire before and four weeks after treatment regarding following parameters: itching, fatigue, heaviness, numbness, cramp, swelling and sensitiveness. Patients rated their symptoms from 0 to 4 (0: absent; 1: mild; 2: moderate; 3: severe; 4: very severe).. Complaints, which were scored by patients before and after treatment, decreased. Among the single-drug groups, itching score decreased more in Group B, whereas scores of fatigue, heaviness, numbness, cramp and swelling decreased more in Group A. But the difference was not significant, statistically. But all complaints decreased significantly in Group C. Difference of scores after treatment revealed no statistical significance in Group A and B, but scores of Group C produced a significant difference when compared with Group A and B.. Results demonstrate that a combination of calcium dobesilate and oxerutin shows a better improvement of complaints. These observations have to be confirmed in larger series with objective tests. Changes of quality of life after a combination therapy might also be of interest.

This study evaluated the clinical efficacy of Venoruton (O-(beta-hydroxyethyl)-rutosides) (HR) (Novartis Consumer Healthcare) in subjects with severe chronic venous insufficiency (CVI).. Patients were included in an average 8-month follow-up registry. At the end of the study 3 spontaneous groups emerged: a group treated with HR 2 g/day, a second group with HR 1 g/day and elastic stockings, and another group with stockings only. The age range was between 45 and 55. The 3 resulting groups were comparable clinically and for age/sex distribution. There were no differences in ambulatory venous pressure (AVP) at inclusion; microcirculatory and clinical evaluations were comparable.. At 8 months there was a decrease in skin resting flux in all groups. Better results (P<0.05) were obtained in the group using the higher dosage and the associated treatment. Stockings alone were less effective (P<0.05). There was significant decrease (P<0.05) in capillary filtration (RAS) in all groups with an advantage in the combination group (P<0.021). HR alone was more effective (P<0.05) than compression alone. There was an improvement in the symptomatic score in all groups with better results (P<0.5) in the combined group; HR alone was more effective (P<0.025) than compression alone. The clinical severity score was reduced (P<0.05) in all groups with better results in the combined group. HR alone was more effective (P<0.05) than compression alone. The venous disability score indicated that HR alone was more effective (P<0.025) than compression. No side effects or tolerability problems were observed with HR. Compliance of HR was also very good. A cost comparison was made considering a comparable control groups (cost of best standard management=100%). Cost in group A was 44% of standard costs; cost in group B (HR+stockings) was 48% of standard costs, and cost in group C (stockings only) was 67% (P<0.05).. The study confirms the long-term efficacy of HR in CVI patients. Controlling signs/symptoms and edema in CVI with HR also prevents the most severe complications of CVI.

Damage to endothelial cells is common in vascular disorders and in reactions associated with transplantation. An elevated number of circulating endothelial cells indicates the extent of endothelial damage in a variety of disorders. In chronic venous insufficiency (CVI), the number of endothelial cells is abnormally increased, and this can be considered an important indication of endothelial damage. A group of 23 subjects with two levels of CVI (severe and very severe with previous ulcerations) with an increased endothelial cell count (seen by microscopy) was studied and treated for 4 weeks with oral Venoruton (0-[beta-hydroxyethyl]-rutosides) (1 g/day) to evaluate the effects of treatment on the circulating endothelial cells in blood taken from a peripheral leg vein. The controls comprised two groups with comparable age and sex distribution, one of healthy individuals and one of CVI subjects. After 4 weeks, a significant decrease was noted in endothelial cells both in subjects with CVI and in those with very severe CVI with previous ulcerations. This study suggests that endothelial cells may play a significant role in venous disease, being both an indication of severe disease and a further problem in itself. The use of Venoruton appears to decrease the number of circulating endothelial cells. This suggests an important role of this compound in protecting the endothelium and offers new potentially important therapeutic options that are not limited only to venous disease.

The aim of this study was to demonstrate whether and how HR (Venoruton(1000), Paroven, 0-[beta-hydroxyethyl]-rutosides) and Daflon (diosmin, 500 mg) were comparatively effective in improving the microcirculation in venous hypertension and microangiopathy.. A group of 90 patients with severe venous hypertension due to chronic venous insufficiency, ankle swelling, and lipodermatosclerosis were included. After informed consent, patients were randomized into a Venoruton and a Daflon (DF) group: patients in the Venoruton group received oral HR (2 g/day for 8 weeks); those in the Daflon group received three 500-mg tablets daily every 8 hours. The two groups were comparable for age and sex distribution. The mean age was 41 years (SD +/- 11) in the Venoruton group (46 patients) and 41.3 (SD +/- 12) in the DF group (44 patients).. There were no differences in microcirculatory parameters between the Venoruton and DF treatment groups at inclusion. There was no significant change between inclusion and measurements at 8 weeks in the DF group. In comparison, a significant decrease (P < .05) in RF (resting skin flux) and RAS (rate of ankle swelling) was observed in the Venoruton group (P < .001). The decrease in capillary filtration was associated with improvement in signs and symptoms (measured by an analogue scale line) (P < .05). Symptomatic improvement was clinically and statistically significant and important only in the Venoruton group. No side effects and no drop-outs were observed.. Venous microangiopathy was improved by the treatment with Venoruton. The comparison with Daflon indicates that HR is comparatively more effective both on microcirculatory parameters and on signs and symptoms.

The aim of this study was to investigate, if the the combined treatment of compression stockings and drug treatment with oxerutins (O-(beta-hydroxyethyl)-rutosides, Venoruton) provides additional benefit for patients with chronic venous insufficiency (CVI) compared to compression treatment alone. Oxerutins belong to the group of oedema protective agents and possess anti-exudative and membrane protective activity. A total of 133 female patients with CVI grade II participated in this double-blind, randomised, multi-centre, parallel-group study with two treatment groups. The whole study lasted for 19 weeks, and consisted of a one week placebo run-in phase, 12 weeks treatment phase, followed by a 6 weeks treatment-free follow-up period. All patients received a basis compression therapy that consisted of standard compression stockings. In order to standardise initial fitting of stockings in this multi-centre setting, stockings were fitted after one week of standard diuretics starting at baseline and then stockings were worn for the following 11 weeks. Patients were randomised to receive oxerutins (2 x 500 mg daily) or matching placebo. Leg volumes (water displacement) and associated subjective symptoms (visula analogue scale) were measured during a placebo run-in period at enrolment (week - 1) and half a week later (week - 1/2), at baseline week 0), at 4, 8, 12 weeks on treatment, and again after a 3- and 6-weeks treatment-free follow-up. The primary efficacy criterion, the area under the baseline from week 0 to week 18 (AUB0-18) of leg volume changes, as measurement of the global change of leg oedema during the study, resulted in a superior reduction of -5589 ml.d for the combined treatment with oxerutins compared to -2101 ml.d for placebo (p = 0.012). The mean change of leg volume compared to baseline after 12 weeks of treatment was -63.9 ml for stockings and oxerutins, and -32.9 ml for the patients who received stockings and placebo (p < 0.05). Oxerutins showed a prolonged effect in the follow-up phase compared to placebo, with mean AUB values for week 12 to week 18 of -1769 ml.d versus -133 ml.d (p < 0.01). The study demonstrated that the combined therapy of compression stockings and drug treatment with oxerutins is significantly superior in reducing leg oedema resulting from chronic venous insufficiency compared to compression treatment alone.

Oxerutins (O-(beta-hydroxyethyl)rutosides, HR, Venoruton) and horse chestnut extract (HCE) are active principles of first priority for the pharmacological treatment of chronic venous insufficiency (CVI). The efficacies of both compounds were shown in numerous, double-blind, randomized, placebo controlled clinical trials. Besides the direct comparison of the two compounds the aim of the study was to investigate the initial dose/maintenance dose concept for HR. 137 female, postmenopausal patients with CVI II finished the study according to protocol. Following one week placebo run-in the patients were treated either with 1000 mg/d HR, 600 mg/d HCE or 1000 mg/d for 4 weeks and than with 500 mg/d HR within the initial dose/maintainance dose concept for 12 weeks and observed for further 6 weeks. A main confirmative criterion was the volume reduction of the leg. Subjective criteria were descriptively evaluated. HR (1000 mg/d) was proven to be equivalent or better, reducing the leg volume (AUB0-18) by -5273 +/- 11418 ml.d compared to -3187 +/- 10842 ml.d under HR (1000 mg/d and 500 mg/d), and -3004 +/- 7429 ml.d under HCE-treatment. Both compounds exhibit a substantial carry-over effect. The maintenance posology of HR is able to stabilize the therapeutic obtained under initial dose conditions.

Abnormal increase of erythrocyte aggregation and reduction of profibrinolytic activity are the two most frequent biological perturbations found in chronic venous insufficiency (CVI). A randomised, controlled, double blind trial was undertaken on 85 patients suffering from grade 1 and 2 CVI, to compare troxerutin with placebo. Two types of biological parameters were measured after 15 days of treatment. Erythrocyte aggregation as evaluated with a Myrenne erythroaggregometer by the indices M (stasis) and M1 (3s-1) progressed favorably in the troxerutin group. The values of M1 at D15 (p < 0.05), and the progression of M (p < 0.001) and M1 (p < 0.01) from D0 to D15, are significantly better in the troxerutin group. Progression of fibrinolytic activity at rest was not significantly different between the 2 groups. Conversely, the progression from D0 to D15 of the values after occlusion of euglobulin lysis time (p < 0.01), tPA (p < 0.01), and PAI activity (p < 0.05) are significantly better in the troxerutin group. The fibrinolysis capacity estimated by euglobulin lysis time (p < 0.01) and tPA (p < 0.05) also progressed favorably in the troxerutin group. These results confirm the anti-erythrocyte aggregation effect of troxerutin, and suggest a favorable effect on blood fibrinolytic activity. They could explain the positive action of this drug on stasis, capillary perfusion and trophic complications of CVL.

Oxerutins (Venoruton) and troxerutin (CAS 7085-55-4) are both mixtures of O-(beta-hydroxyethyl)-rutosides used for the treatment of chronic venous insufficiency. As di-O-(beta-hydroxyethyl)-rutosides and 7-mono-O-(beta-hydroxyethyl)-rutoside were found to be more active with regard to free radical scavenging compared to tri-O-(beta-hydroxyethyl)-rutoside the aim of this study was to compare oxerutins and troxerutin clinically. 12 female, post-menopausal patients with chronic venous insufficiency grade II participated in this double-blind study with random allocation to the treatment groups. They received 900 mg/day oxerutins or troxerutin for 12 weeks and were observed for 4 further weeks without treatment. Leg volumes (water displacement) and subjective symptoms (VAS, visual analogue scale) were evaluated before and following 2, 4, 8, 12 and 16 weeks. Both treatments were active in reducing leg volumes and in ameliorating subjective symptoms (mean volume reduction -167 +/- 157 ml x week). Volume reduction totalled to -261 +/- 154.2 ml x week for oxerutins and -73.2 +/- 97.1 ml x week for troxerutin. The difference is statistically significant (p = 0.04). The findings with subjective symptoms were in good accordance to the objective volume measurement. Oxerutins revealed a remarkable carry over effect.

Forty-three patients recruited from general practice with symptom-producing chronic venous insufficiency in the lower limbs participated in a randomized double-blind clinical trial with Venoruton (300 mg x 3) or a placebo for 28 days. Twenty-eight patients were treated with Venoruton and 19 with a placebo. None of the patients received other forms of treatment for chronic venous insufficiency. No differences were observed between the two groups as regards changes in symptoms (swelling, pain, heaviness, restlessness, itching and cramps) the subjective assessment of the discomfort in the extremities or the circumference of the limbs. Venoruton does not appear to have any effect on chronic venous insufficiency in the lower limbs.

Sixteen chronic schizophrenic subjects were treated for 3 months each with either a benzo-pyrone (Paroven/Venoruton, Zyma) or a placebo in a randomized, double-blind crossover trial. They continued to take their previous drug therapies. Therapeutic effects were measured by the Brief Psychiatric Rating Scale (BPRS), by self-assessment, and by assessment by a relative. Eleven patients completed the trial in relation to BPRS assessment. When on the active substance, as compared with the placebo, they showed a mean improvement of 27% (significant at the 1% level). Ten patients completed the trial in relation to the self and relative's assessments. There were improvements of 16% and 13%, respectively (significant at the 5% levels). Half the patients showed improvements on all the tests. Their improvements were 49%, 31%, and 21%, respectively. There was evidence that the active substance began to have an effect within 2 weeks. No side effects were observed with the active substance.
