Retrospective analysis of the combined therapy of terazosin with chlormezanone for chronic prostatitis/chronic pelvic pain syndrome / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the efficacy and safety of the alpha1-receptor inhibitor terazosin combined with chlormezanone in the treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).</p><p><b>METHODS</b>A total of 168 CPPS patients, aged 20 -50 (mean 32.9) years and with the disease course of 3 months to 7 years (mean 17 months), were equally randomized into a terazosin group (n = 58), a chlormezanone group (n = 38) and a terazosin + chlormezanone (T + C) group (n = 72), and treated accordingly for 4 weeks. All the patients were scored on NIH-CPSI (National Institute of Health-Chronic Prostatitis Symptom Index) after the treatment and the therapeutic effects were compared among the three groups.</p><p><b>RESULTS</b>Of the total number of patients, 159 completed the treatment and were evaluated, including 55 of the terazosin group, 35 of the chlormezanone group and 69 of the T + C group. After the treatment, the NIH-CPSI scores of the three groups decreased from 24.05 +/- 3.02 to 16.15 +/- 3.25 (mean 7.90), from 23.43 +/- 3.58 to 17.51 +/- 3.08 (mean 5.92), and from 23.93 +/- 3.30 to 15.01 +/- 3.08 (mean 8.92), respectively, with statistically significant differences from pretreatment (P < 0.05) as well as between the combined therapy group and the other two (P < 0.05). The adverse events included postural hypotension (17.1% in the terazosin group and 15.4% in the T + C group), dysspermatism (3.4% in the terazosin group only), lassitude, fatigue and anorexia (18.5% in the chlormezanone group and 12.6% in the T + C group). Nine of the patients failed to accomplish the treatment because of adverse events, 3 (5.2%) in the terazosin group, 3 (7.9%) in the chlormezanone group and 3 (12.6%) in the T + C group.</p><p><b>CONCLUSION</b>Both terazosin and chlormezanone can relieve the symptoms in CP/CPPS patients and improve their life quality, but their combined use may produce a better efficacy than either terazosin or chlormezanone used alone.</p>
