Efficacy of Combination of Solifenacin and Tadalafil Versus Solifenacin Alone in Treatment of Overactive Bladder in Females

ClinicalTrials.gov · COMPLETED, 2025

80 participants

Abstract

Overactive bladder (OAB) is characterized by urinary urgency with or without urge urinary incontinence, usually with frequency and nocturia, in the absence of urinary tract infection or other obvious pathology. Antimuscarinic agents such as solifenacin are commonly used but may provide incomplete symptom control. Tadalafil (a Phosphodiesterase type 5 inhibitorsinhibitor) has been reported to improve lower urinary tract symptoms and may offer additional benefit in overactive bladder. This randomized controlled trial evaluates the efficacy and tolerability of solifenacin 5 mg plus tadalafil 5 mg versus solifenacin 5 mg alone in females with overactive bladder using the Overactive Bladder Symptom Score (OABSS).

Conditions: Overactive Bladder.

Primary outcome: Change in total Overactive Bladder Symptom Score (OABSS) at 1 month.

Enrollment: 80 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 80 participants or records.
