INTRODUCTION: To compare the efficacy and safety between tadalafil once-a-day and tadalafil on-demand dosing regimen in patients with ED. MATERIALS AND METHODS: A systematic search of Medline, Embase, and Cochrane Library was performed to identify all randomized controlled trials (RCTs) that compared tadalafil used a once-a-day with an on-demand dosing regimen for erectile dysfunction. A secondary hand-search was performed in relevant journals, references, and the grey literature. Meta-analyses were performed using Review Manager version 5.3.0. RESULTS: Six RCTs involving a total of 1,534 patients were included in this review. All studies reported the International Index of Erectile Function-Erectile Function domain score and the results of the meta-analysis showed no difference between the groups. The overall pooled estimated weighted mean differences (WMD) was 0.97 (95% CI -0.37 to 2.32; p = 0.16). Meta-analyses of Sexual Encounter Profile questions 2 and 3 (SEP-2 and SEP-3) showed that the once-a-day dosing regimen was superior to the on-demand regimen with statistical significance. The WMD of SEP-2 and SEP-3 were 10.32 (95% CI 3.16-17.48; p = 0.005) and 11.07 (95% CI 2.57-19.56; p = 0.01), respectively. Both dosing regimens of tadalafil showed similar complication rates. The meta-analyses of adverse events showed no significant differences. CONCLUSIONS: The efficacy rates of tadalafil once-a-day and on-demand were similar. No significant difference in safety was found between the 2 dose regimens of tadalafil.
