Meta-Analysis of the Long-Term Efficacy and Tolerance of Tadalafil Daily Compared With Tadalafil On-Demand in Treating Men With Erectile Dysfunction
Abstract
BACKGROUND: Erectile dysfunction (ED) is highly prevalent in aging men. Tadalafil daily and on-demand are widely used for the treatment of ED. AIM: We performed a meta-analysis to evaluate the efficacy and safety of tadalafil daily compared with tadalafil on-demand in treating men with ED after at least 24 weeks of long-term treatment. METHODS: Randomized controlled trials of tadalafil daily vs on-demand in treating men with ED were searched using MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. Systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-analyses. The data was calculated by RevMan version 5.3.0. The references of related articles were also searched. OUTCOMES: International Index of Erectile Function-Erectile Function domain, sexual encounter profile question 2 (SEP2), SEP question 3 (SEP3), any treatment-emergent adverse event (AE), discontinuation due to AEs, myalgia, back pain, headache, dyspepsia, and nasopharyngitis. RESULTS: 4 articles, including 1,035 participants were studied. The analysis found that tadalafil daily had a greater improvement than tadalafil on-demand in terms of International Index of Erectile Function-Erectile Function (mean difference (MD) 1.24; 95% CI 0.03-2.44; P = .04), SEP2 (MD 10.08; 95% CI 9.15-11.01; P < .00001) and SEP3 (MD 8.19; 95% CI 2.09-14.29; P = .009) in treating ED after at least 24 weeks treatment cycle. For safety, tadalafil on-demand had a higher incidence of…
