Efficacy and Safety of "On-Demand" Dapoxetine in Treatment of Patients with Premature Ejaculation: A Meta-Analysis.

BACKGROUND The aim of this study was to assess the efficacy and safety of "on-demand" dapoxetine in the treatment of premature ejaculation (PE). MATERIAL AND METHODS We performed a meta-analysis of intravaginal ejaculatory latency time (IELT), patient-reported global impression of change (PGIC), perceived control over ejaculation (PCOE), and drug-related adverse effects (AEs). We searched Medline, PubMed, Embase, CNKI, Wanfang, and VIP databases up to May 30, 2018 with the following search terms: "dapoxetine" or "SSRIs" and "premature ejaculation" or "sexual dysfunction". RESULTS Our analysis included 11 RCTs (8521 cases and 4338 controls). We found that IELT, PGIC, and PCOE in PE patients with "on-demand" dapoxetine were significantly higher than in the control group, and we observed higher proportions in 60 mg vs. 30 mg dapoxetine. The AEs were mild and tolerable. CONCLUSIONS "On-demand" dapoxetine is effective and safe for patients with PE, and a dose of 60 mg may be more effective than 30 mg.
