pregabalin and Premature-Ejaculation

Although premature ejaculation (PE) is a common sexual dysfunction, the available options for PE treatment remain unsatisfactory.. To evaluate the effect of on-demand oral pregabalin on the intravaginal ejaculation latency time (IELT).. We conducted a multiarm double-blinded placebo-controlled randomized clinical trial that enrolled 120 patients with PE who were divided equally into 3 groups (A, B, and C). 4 patients were excluded, 39 patients received 150 mg pregabalin (group A), 39 patients received 75 mg pregabalin (group B), and 38 patients received placebo (group C). All patients were encouraged to engage in sexual relations twice per week for 2 weeks and to take the medication 1-2 hours before sexual intercourse. A stopwatch was used to evaluate IELT.. The main outcome measure are the improvement of IELT and the reported adverse events.. IELT significantly improved in patients who received 150 mg pregabalin, but there was no change in the other groups.. Most PE patients showed a significant improvement after receiving on-demand pregabalin (150 mg).. The strength of this study is that it is the first randomized controlled trial to evaluate the efficacy of pregabalin in treatment of PE. The main limitations were the small number of patients, IELT was the only primary outcome of the study, and the pregabalin cap can be identified by the patient.. Oral pregabalin seems to be a promising drug for additional evaluation as a new treatment for PE. More studies are needed to evaluate the suitable dose, duration, timing, and its safety profile.
