Abstract | OBJECTIVE: METHODS: Eight hundred and eleven men with symptomatic BPH (international prostdate symptom score, I-PSS > or = 10) were recruited in 11 European countries for a 12-month, double-blind randomized trial. After a 4-week run-in period, 704 patients were randomly assigned to either tamsulosin 0.4 mg per day (N = 354) or Permixon 320 mg per day (N = 350). I-PSS, QoL and maximum urinary flow rate (Qmax) were evaluated at baseline and periodically for 1 year. Prostate volume and serum prostate-specific antigen (PSA) were measured at selection and at endpoint. The endpoint analysis was performed on the per-protocol (PP) population of 542 patients ( tamsulosin: N = 273; Permixon: N = 269). RESULTS: At 12 months, I-PSS decreased by 4.4 in each group and no differences were observed in either irritative or obstructive symptom improvements. The increase in Qmax was similar in both treatment groups (1.8 ml/s Permixon, 1.9 ml/s tamsulosin). PSA remained stable while prostate volume decreased slightly in the Permixon-treated patients. The two compounds were well tolerated, however, ejaculation disorders occurred more frequently in the tamsulosin group. CONCLUSION:
