Abstract | INTRODUCTION: This study aims to compare the efficacy of propiverine hydrochloride immediate release (IR), propiverine hydrochloride extended release (ER) and placebo for the treatment of overactive bladder syndrome. The primary outcome measure is incontinence episode frequency, with secondary outcome measures including mean volume per void and quality of life as assessed on King's Health Questionnaire. MATERIAL AND METHODS: The double-blind, double-dummy, randomized study compared IR 15 mg twice daily, ER 30 mg once daily and placebo in 3 parallel groups. After a run-in period of 7 days, the patients were treated for 32 days. Nine hundred and eighty-eight patients were randomized, and 910 patients completed the protocol without major violations. RESULTS: The number of incontinence episodes/24 h decreased by 2.26 in the IR group (p < 0.001 vs. placebo), by 2.46 in the ER group (p < 0.0001 vs. placebo) and by 1.75 in the placebo group. The most frequent adverse event was dry mouth with 22.8% of the patients in the IR group, 21.7% in the ER group and 6.4% in the placebo group. The overall tolerability was rated 'very good' or 'good' by more than 80% of the investigators and patients in all 3 groups. CONCLUSIONS:
