Comparison of Alpha Blockers in Treatment of Premature Ejaculation: A Pilot Clinical Trial
Abstract
BACKGROUND: Premature ejaculation (PE) is the most common sexual disorder in men and studies reported prevalence up to 30% (1, 2). PE is not a life-threatening medical condition but it influences the quality of life (QoL). OBJECTIVES: The aim of this study was to compare the efficiency, and safety of alpha blocker drugs in the treatment of patients with premature ejaculation (PE). Additionally we investigated the quality of life (QoL) in patients with PE who were treated with alpha blocker drugs. MATERIALS AND METHODS: This study was a pilot clinical trial. Prospectively documented 108 patients with PE were treated and were followed-up in urology outpatient clinic. All patients were divided into 5 groups according to used alpha blocker agents which were determined by simple randomization. Silodosin 4mg (Group 1, n = 21), tamsulosin hydrochloride 0.4mg (Group 2, n = 23), alfuzosin 10mg (Group 3, n = 22), terazosin 5mg (Group 4, n = 21), doksazosin mesylate 4mg (Group5, n = 21), were used for treatment. The demographic parameters of patients, pre and post treatment intravaginal ejaculation latency time (IELT), PE Profile (PEP), and QoL index were recorded and evaluated. Effectiveness of treatment was evaluated by measuring IELT. Additionally, side effects of drugs were recorded. P < 0.05 was considered statistically significant. RESULTS: All alpha blocker drugs were statistically effective for preventing PE. Notably, silodosin seemed to be more effective for preventing PE than…
