Abstract
INTRODUCTION
Although premature ejaculation (PE) is a common sexual dysfunction, the available options for PE treatment remain unsatisfactory.
AIM
To evaluate the effect of on-demand oral pregabalin on the intravaginal ejaculation latency time (IELT).
METHOD
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.
MAIN OUTCOME MEASURE
The main outcome measure are the improvement of IELT and the reported adverse events.
RESULTS
IELT significantly improved in patients who received 150 mg pregabalin, but there was no change in the other groups.
CLINICAL IMPLICATIONS
Most PE patients showed a significant improvement after receiving on-demand pregabalin (150 mg).
STRENGTH & LIMITATIONS
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.
CONCLUSION
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.
