Comparison of alfuzosin 10 mg with or without propiverine 10 mg, 20 mg in men with lower urinary tract symptom and an overactive bladder: randomised, single-blind, prospective study

Abstract

Summary Purpose The efficacy and safety of treatment with alfuzosin 10?mg plus propiverine 10 or 20?mg in men with lower urinary tract symptoms (LUTS) and an overactive bladder were investigated. Materials and methods In this parallel?arm, prospective, multicentre, single?blind study, men who were ≥?40?years old, had an International Prostate Symptom Score (IPSS) of ≥?8, an Overactive Bladder Symptom Score (OABSS) of ≥?3 and an OABSS urgency item score of ≥?2 were randomised in a 1?:?1?:1 ratio to receive alfuzosin 10?mg alone (Group A) or with propiverine 10?mg (Group B) or 20?mg (Group C) for 8?weeks. Four and 8 weeks after commencing treatment, OABSS was measured along with IPSS, maximal urinary flow rate ( Q max ) and postvoid residual volume (PVR). Adverse events were recorded. Results A total of 135 men, including 43 in Group A, 48 in Group B and 44 in Group C, completed the study. Relative to baseline, all groups demonstrated significant reductions in OABSS and the IPSS after eight treatment weeks (p? Q max and PVR in the three groups did not achieve statistical significance. Overall adverse event rates were higher in Group C but not significant compared with others.
