Abstract:
Objective To investigate the efficacy and side effects of 4?-adrenergic receptor(?- AR)antagonists in the treatment of chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS).Meth- ods Totally,325 patients(mean age,33.2 year;disease history,2.4 years)with CP/CPPS were randomly divided into Prazosin(n=95),Terazosin(n=78),Phenoxybenzamine(n=27),and Doxazosin mesylate controlled release tablets(n=72)groups.Some antibiotics and medications were used for allopathy.In addi- tion,53 cases with no?-AR antagonist treatment served as control group.The efficacy and side effects in all the patients were observed and recorded.The chronic prostatitis symptom index(CPSI)was used to evaluate the efficacy.Results In control group,22(41.5%)patients responded well to the treatment( CPSI mark drop≥5)and 31(58.5%)failed to respond to the treatment(CPSI mark drop＜5).In study group,199 (73.2%)patients responded well to the treatment,and 73(26.8%)failed.The difference in efficacy be- tween?-AR antagonists and placebo treatment was significant(P＜0.01).In study group,specifically,the effective rate was 55.6% in Phenoxybenzamine,78.2% in Terazosin,76.4% in Doxazosin mesylate con- trolled release tablets,and 71.6% in Prazosin groups.The main side effects of?-AR antagonists were postur- al hypotension(a rate of 23.2% for Prazosin,17.9% for Terazosin,22.2% for Phenoxybenzamine,and 8.3% for Doxazosin mesylate controlled release tablets)and dysfunction of ejaculation(only in Phenoxy- benzamine group with a rate of 51.9%).The rates of withdrawing treatment due to side effects were in turn 18.5% of Phenoxybenzamine,7.4% of Prazosin,5.1% of Terazosin,and 0% of Doxazosin mesylate con- trolled release tablets.Conclusions As essential medications for the treatment of CP/CPPS,?-AR antag- onists can relieve the clinical symptoms(dropping NIH-CPSI mark significantly),but some side effects should be considered when some medications are selected.
