Randomized, Single-Blind, Parallel Study of the Effectiveness and Safety of Solifenacin versus Propiverine in the Treatment of Overactive Bladder

Abstract

OBJECTIVES: To compare the effectiveness and safety of solifenacin versus propiverine in the treatment of overactive bladder (OAB), in a single-blind, randomized parallel study. METHODS: Sixty-six patients with OAB (14 men and 52 women) were randomly assigned to groups: solifenacin (5 mg/day) or propiverine (20 mg/day) and treated for 8 weeks. The primary outcome variable was mean change from baseline to end of treatment in urgency of the OAB symptom score (OABSS). Secondary outcomes were bladder diary variables: change over 24 h in the mean number of voids (daytime and nighttime), episodes of micturition urgency and incontinence, and mean volume voided. Patients also completed total OABSS a..
