Safety and efficacy of vardenafil in patients with erectile dysfunction: Result of a bridging study in Japan

AIM: Vardenafil is a selective and highly potent phosphodiesterase type 5 (PDE5) inhibitor for the treatment of erectile dysfunction (ED), with improved selectivity for PDE5 and demonstrated efficacy for improving sexual function in men with ED. The current study investigated the safety and efficacy of this new PDE5 inhibitor in Japanese men with ED. METHODS: This was a prospective, double blind, randomized clinical trial designed to evaluate the efficacy and safety of vardenafil. Following a 4-week treatment-free observation period, 283 eligible patients were randomized to 12 weeks treatment with vardenafil 5 mg, 10 mg, 20 mg, or placebo. Primary efficacy responses were assessed using the scores of Q3 and Q4 of the international index of erectile function (IIEF). RESULTS: All three vardenafil doses showed significantly better improvement than the placebo group in Q3 and Q4 scores of the IIEF questionnaire, either at 12 weeks or at the 'last observation carried forward' (LOCF, P < 0.0001). Q3 scores were improved to 4.06 with vardenafil 5 mg, 4.53 with vardenafil 10 mg, and 4.64 with vardenafil 20 mg, versus 3.17 with placebo. Comparable scores for Q4 were 3.47, 4.15 and 4.31 versus 2.31 for placebo. Up to 86% of patients achieved improved erections as assessed by the global assessment question (GAQ). Reported adverse event rates were 35.3%, 45.3% and 54.5% with vardenafil 5 mg, 10 mg and 20 mg, respectively, versus 21.1% in the placebo group. No serious adverse drug reactions were reported. The most common treatment-emergent adverse events were transient headache, flushing and rhinitis, which were mostly mild. CONCLUSION: Vardenafil is an effective and well-tolerated treatment for ED and provides improvement in key indices of erectile function among Japanese men with ED. The results of our trial show that up to nearly 90% of patients achieve improved erections with the administration of vardenafil.     

Efficacy and safety of vardenafil in renal transplant recipients with erectile dysfunction

Erectile dysfunction (ED) profoundly affects the quality of life. The prevalence of ED in renal transplant recipients is reported by high as 50% to 60%. We evaluated the efficacy and safety of vardenafil in these patients with ED as well as its effects on graft function and on cylosporine or tacrolimus concentrations. Thirty-nine recipients with ED and serum creatinine values<2 mg/dL were treated with vardenafil. ED was assessed using the self-administered International Index of Erectile Function (IIEF). ED was diagnosed by using penile color-Doppler ultrasonography and intracavernosal injection. Vardenafil efficacy was assessed by readministering the IIEF questionnaire after 4 weeks of therapy. Serum creatinine levels, creatinine clearances, and cyclosporine/tacrolimus concentrations were measured before and after vardenafil therapy. Twenty-one recipients with ED served as placebo controls and 15 without ED as another control group. The IIEF scores improved from 12.80+/-3.5 to 26.46+/-2.4 in vardenafil-treated patients with ED (P<.001). Renal function and cyclosporine/tacrolimus concentrations did not change with vardenafil therapy. Side effects were observed in 7 (18%) patients: headache in three, palpitations in one, flushing in two, and dyspepsia in one. This study demonstrated that ED improved with vardenafil in renal transplant recipients with ED. For 4 weeks vardenafil therapy was free of side effects. Renal function tests did not change. Also, no dose change in immunosuppressive drugs was required during 4 weeks of verdanafil therapy.     

Positive effect of counseling and dose adjustment in patients with erectile dysfunction who failed treatment with sildenafil

OBJECTIVE: Many patients with erectile dysfunction (ED) stop using sildenafil due to subjective failure. This study examined whether counseling and maximal dosing (100 mg) could achieve better treatment compliance and could possibly improve treatment outcome. MATERIAL AND METHODS: Patients were recruited by newspaper advertisements and referred to 5 ED centers throughout the country. Details about their previous experiences with sildenafil were recorded and following an explicit explanation about the nature and action of the drug, were offered to enter the study. Instructions on drug use were provided during each visit in which four 100 mg Sildenafil tablets were provided. Treatment outcomes were assessed by the international index of erectile function (IIEF) questionnaire after taking 4 and 8 tablets. In 2 ED centers a short video with sexual counseling content was added in between visits. RESULTS: The study cohort was comprised of 220 patients aged 27-88 years. The majority reported having received limited or no instructions on drug use when sildenafil was first prescribed. A significant increase in IIEF erectile function domain scores (EFDS) between visits 1, 2 and 3 was observed (10.96+/-0.40, 16.73+/-0.51 and 17.82+/-0.55 mean+/-SE, respectively), with 23.6% of the study patients achieving normal erectile function at the end of the study. The parameters of age and initial severity of ED most influenced treatment success. CONCLUSIONS: Counseling and dose adjustment were directly influential in achieving an excellent response to a second trial of sildenafil in patients with ED who had previously failed treatment with the drug, and obviated their needing to seek more invasive measures.     

Efficacy of sildenafil citrate in treatment of erectile dysfunction: effect of type 2 diabetes

PURPOSE: To assess efficacy of sildenafil citrate in treatment of erectile dysfunction: effect of type 2 diabetes. MATERIALS AND METHODS: A total of 466 male patients with erectile dysfunction (ED) were enrolled in this study. Of them 382 were diabetic and 84 were non-diabetic. Patients were screened for ED using the erectile function domain of the International Index for Erectile Function (IIEF). Patients underwent routine laboratory investigations, in addition to total testosterone and prolactin assessment. To assess the effect of diabetes on efficacy of sildenafil, we compared the pre and post sildenafil responses to erectile function domain, Q3, Q4. Overall satisfaction and global efficacy question (GEQ) were also assessed. RESULTS: Mean age +/- S.D. was 53 +/- 8.4 and 49.7 +/- 10.6 years for patients with and without diabetes respectively. There were significant associations between increased severity of ED and longer duration, poor metabolic control and presence of more than one diabetes-related complication (p < 0.05 for each). Differences were significant between pre and post sildenafil administration regarding erectile function domain, Q3, Q4 (p < 0.05 for each). In the non-diabetic patients the GEQ and the overall satisfaction were significantly higher than in diabetics (p < 0.05 for each). Global efficacy question was significantly low in patients with fair and poor metabolic control, longer duration of diabetes, and patients with diabetic complications (p < 0.05 for each). CONCLUSIONS: Sildenafil is an effective treatment for diabetic patients with ED. Although the efficacy of sildenafil was negatively affected by factors as poor control and longer duration of diabetes and presence of more than one diabetes-related complication, however, the global efficacy and the overall patients' satisfaction were high.

Endothelial microparticles correlate with erectile dysfunction in diabetic men

Cell-derived microparticles are supposed to be involved in endothelial dysfunction and atherogenesis. This study aimed to evaluate circulating microparticles in diabetic subjects with erectile dysfunction (ED) and their relation with endothelial dysfunction. Thirty diabetic men with ED and 20 age-matched control subjects without ED were assessed for circulating microparticles and endothelial dysfunction. Flow cytometry was used to assess microparticles by quantification of circulating endothelial (EMP, CD31(+)/CD42b(-)) and platelet (PMP, CD31(+)/CD42b(+)) microparticles in peripheral blood. Endothelium-dependent flow-mediated dilation (FMD) was evaluated in the right brachial artery after reactive hyperemia. Compared with non-diabetic subjects, diabetic men presented significantly higher numbers of EMP (P=0.001), and reduced FMD (P=0.01), with a significant inverse correlation between the number of circulating EMP and the International Index of Erectile Function (IIEF) score (r=-0.457, P=0.01). Multivariate analysis correcting for age, anthropometric indices, glucose and lipid parameters, FMD and PMP identified EMP as the only independent predictor for IIEF score (P=0.03). EMP are elevated in impotent diabetic subjects and independently involved in the pathogenesis of ED.
