Abstract
Objective: to compare the efficacy of dapoxetine in treatment of primary and secondary premature ejaculation. Materials and methods. The study included 60 patients with premature ejaculation (PE). Depending on the form of premature ejaculation they were divided into two groups: 27 patients with primary PE (group 1) and 33 patients with secondary PE (group 2). Patients were recommended to take dapoxetine 30 mg 1 hour before intercourse. A follow-up visit was scheduled on day 30 after receiving the drug. The intravaginal ejaculation latency time (IELT) and the Premature ejaculation diagnostic tool (PEDT) score were evaluated before dapoxetine was given and after 30 days from the start of the study. The significance of differences between baseline and follow-up values were compared using Wilcoxon’s test. In both groups, the proportion of patients with an incomplete response (IELT less than 2 minutes, PEDT more than 10) to symptomatic therapy with dapoxetine was evaluated. The proportion of patients with incomplete response to therapy was compared using the chi-square test. Results. The median IELT among all patients before starting therapy was 63 seconds (interquartile interval [IQR]: 28.75-94). After one month of therapy median IELT increased to 119 seconds (IQR: 58.75-321.75). Median PEDT score was 16 (IQR: 13-19) at baseline and 7 (IQR: 4-12) at follow-up. In group 1, the median IELT increased from 57 to 83 seconds (p = 0.02088), and in group 2, the median IELT increased from 70 to 173 seconds (p<0.00001). The mean PEDT score decreased to 7 in both groups (p<0.00001). Incomplete response to therapy was observed in 66.7% of patients in group 1 and in 39.4% of patients in group 2. The difference between two groups was statistically significant (p=0.035456). Conclusion. Symptomatic therapy with dapoxetine has a positive effect on the intravaginal ejaculation latency time and patient satisfaction in both primary and secondary premature ejaculation. However, the incidence of incomplete response to therapy is higher in patients with primary premature ejaculation, which may be due to characteristic differences in the pathogenesis of primary and secondary premature ejaculation.
