title: Effect of once-daily alfuzosin on urinary symptoms and flow rate in benign prostatic hyperplasia : a 24-hour home-uroflowmetry evaluation.
abstract: OBJECTIVE
  To analyse the clinical and 24-hour urinary flow efficacy of alfuzosin 10mg once daily (OD), by means of the International Prostate Symptom Score (I-PSS) and home-based uroflowmetry (P-Flow) measurement, in patients with lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia.
  
  
  METHODS
  In this open-label trial, 12 male patients (median age 67 years) with an I-PSS >15 (median 16) and maximum urinary flow (Q(max)) <15 mL/sec were evaluated. Patients underwent two days of P-Flow evaluation, and then received alfuzosin 10mg OD from day 3 to day 9. On days 7 and 8 they underwent further P-Flow evaluation. A second post-baseline evaluation I-PSS was recorded on day 9.
  
  
  RESULTS
  Overall, 328 urinary flows were recorded and evaluated, an average of 27 flows per patient. A statistically significant improvement in mean maximum flow: (Q(max)) [10.8 +/- 2.8 vs 12.4 +/- 3 mL/sec; p = 0.02] and urinary voiding volume (219 +/- 70 vs 233 +/- 55mL; p = 0.04) were observed after treatment compared with baseline. No differences in the number of urinary flows were observed between baseline and after treatment (13 +/- 2.9 vs 14 +/- 1.8 flows; p = 0.199). A statistically significant difference between the two evaluations was noted for I-PSS (15.7 +/- 0.8 and 9.5 +/- 2; p = 0.02). Mean Q(max) recorded during treatment was always higher than baseline at different daytime evaluations.
  
  
  CONCLUSIONS
  The alfuzosin 10mg OD formulation showed a significant improvement in I-PSS as well as a significant improvement in urinary flow parameters (Q(max)and urinary voiding volume) lasting for 24 hours in patients with LUTS.
