RESUMEN
<p><b>OBJECTIVE</b>To validate the therapeutic efficacy of paroxetine in the treatment of premature ejaculation (PE).</p><p><b>METHODS</b>Eighty PE patients up to the inclusion criteria were equally randomized to an experimental and a control group. We observed all the patients for 4 weeks and recorded the baseline data on intravaginal ejaculatory latency time (IELT) and sexual satisfaction scores, followed by oral medication of paroxetine at 20 mg/d for the patients in the experimental group and placebo for the controls. Thirty days after the treatment, we again recorded IELT and sexual satisfaction scores of the patients.</p><p><b>RESULTS</b>After the treatment, the experimental group showed significantly prolonged IELT ([5.75 +/- 1.24] min) and increased sexual satisfaction score (6.4 +/- 1.2) as compared with the baseline data ([0.89 +/- 0.21] min and [2.7 +/- 0.9]) (P < 0.01). The control group exhibited no significant differences before and after the medication either in the mean IELT or in sexual satisfaction scores ([1.06 +/- 0.28] min vs [0.97 +/- 0.18] min and 3.6 +/- 1.3 vs 3.1 +/- 1.1, P > 0.05).</p><p><b>CONCLUSION</b>Oral medication of paroxetine at 20 mg/d for 30 days could improve IELT and sexual satisfaction in PE patients.</p>
