RESUMO
Objective: To compare the efficacy of tadalafil alone, dapoxetine alone, and tadalafil with dapoxetine as a combination therapy for the treatment of premature ejaculation. Patients and Methods: Eligible patients attended our andrology clinic with premature ejaculation were randomly allocated into three groups: group A (92 participants) received on-demand tadalafil, 5 mg; group B (91 participants) were given on-demand dapoxetine, 30 mg; and group C (89 participants) received on-demand combination of tadalafil, 5 mg, and dapoxetine, 30 mg. We assessed the changes in the intravaginal ejaculatory latency time (IELT) and the satisfaction scores 1, 2, and 3 months after treatment. Results: Highly statistically significant improvements were found in the mean IELT and satisfaction scores 1, 2, and 3 months post-treatment in all groups (P = <0.001). Post hoc analysis suggested this improvement was more pronounced in group C (P < 0.001). Conclusion: Both tadalafil and dapoxetine are effective in the treatment of patients with premature ejaculation, but the combination of both drugs gives better results.
