title: Safety and efficacy of alfuzosin 10 mg once-daily in the treatment of lower urinary tract symptoms and clinical benign prostatic hyperplasia: a pooled analysis of three double-blind, placebo-controlled studies.
abstract: OBJECTIVE
  To examine the efficacy and safety of a once-daily formulation of alfuzosin in a pooled analysis of three parallel, randomized, double-blind, placebo-controlled 3-month studies of patients with lower urinary tract symptoms (LUTS) consistent with clinical benign prostatic hyperplasia.
  
  
  METHODS
  Patients were randomized to receive alfuzosin, 10 mg once-daily (473) or placebo (482) for 12 weeks. Primary efficacy criteria were improvements in the International Prostate Symptom Score (IPSS) and peak urinary flow rate (PFR).
  
  
  RESULTS
  Alfuzosin significantly improved the mean (sd) IPSS, by - 6.0 (5.1) vs - 4.2 (5.7) with placebo (P < 0.005) and the PFR, by + 2.3 (3.8) vs + 1.1 (3.1) ml/s with placebo (P < 0.001), irrespective of prostate size. The significant improvement in LUTS included the irritative and the obstructive subscore of the IPSS and the nocturia criterion; the PFR increased rapidly and significantly, from the first visit (14 days). The quality-of-life score also improved significantly in alfuzosin-treated patients. Alfuzosin was well tolerated; the number of withdrawals for adverse events was comparable in both treatment groups. The most frequently reported adverse event was dizziness (placebo 2.9%, alfuzosin 6.1%). There were no significant changes in blood pressure with alfuzosin compared with placebo, including in elderly and hypertensive patients. Sexual adverse events were rare (abnormal ejaculation, 0.6%).
  
  
  CONCLUSIONS
  The once-daily formulation of alfuzosin, administered at 10 mg with no dose titration is effective, with a good safety profile, especially in elderly and hypertensive patients.
