Abstract
INTRODUCTION: We carried out this systemic review and meta-analysis of relevant randomized controlled trials to determine different dosage regimens of vardenafil in the treatment of male erectile dysfunction (ED). METHODS: Using appropriate keywords, we searched PubMed, the Cochrane Library, and Embase for relevant literature before March 2020. We evaluated odds ratio (OR), weighted mean difference (WMD), and 95% confidence interval (95% CI) to assess the results of each study. RESULTS: We included 14 studies with a total of 3221 patients. Compared with the placebo, vardenafil significantly increased International Erectile Function Index (IIEF) overall satisfaction (WMD 3.37, 95% CI 2.02-4.71), IIEF-erectile function (WMD 7.93, 95% CI 6.00-9.85), IIEF sexual desire (WMD 0.79, 95% CI 0.24-1.35), IIEF intercourse satisfaction (WMD 5.24, 95% CI 3.35-7.13), IIEF orgasmic function (WMD 3.81, 95% CI 2.26-5.35), Sexual Encounter Profile (SEP) Q2 (WMD 26.36, 95% CI 22.95-29.77), and SEP Q3 (WMD 35.18, 95% CI 31.89-38.48). CONCLUSIONS: Vardenafil demonstrated significant efficacy in the treatment of ED, but the optimal dose and course of vardenafil remain to be established.
