Dapoxetine hydrochloride versus paroxetine for the treatment of primary premature ejaculation
Abstract
OBJECTIVE: To investigate the clinical effect and adverse reactions of dapoxetine hydrochloride versus paroxetine in the treatment of primary premature ejaculation by cross-comparison.
METHODS: Based on the clinic-visit time, we equally randomized 148 patients with primary premature ejaculation into groups A and B for a cross-comparison test, the former treated with paroxetine at 20 mg once nightly and the latter with dapoxetine hydrochloride at 30 mg on demand, both for 6 successive weeks, during which we observed the therapeutic effects and adverse reactions. Following 4 weeks of drug discontinuance, we administered dapoxetine hydrochloride at 30 mg on demand for group A and paroxetine at 20 mg once nightly for group B, both for another 6 successive weeks, followed by observation and comparison of the therapeutic effects and adverse reactions.
RESULTS: There were no statistically significant differences in the initial characteristics of the two groups of patients (P > 0.05). Compared with the baseline, the mean intra-vaginal ejaculation latency time (IELT) was dramatically improved after treatment in both groups A (4.43 min) and B (7.12 min), increased by 3.99% and 6.72%, respectively (P<0.001). The patients treated with paroxetine showed significantly longer IELT than those taking dapoxetine hydrochloride in both groups (P<0.001). Findings of the Premature Ejaculation Profile (PEP) and spouses' conditions indicated significant improvement after treatment in the average…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 148 participants or records.
