Persistence with first line anticholinergic medication in treatment-naïve overactive bladder patients

Abstract

Objective. The aim of this study was to evaluate the persistence of first line anticholinergic medication use by patients with overactive bladder (OAB). Data from a hospital outpatient database were matched with information obtained by a telephone survey of patients to determine which patients discontinued use of anticholinergic medication and to identify the reasons underlying discontinuation. Material and methods. The study group included 377 OAB patients (52 men, 325 women) with a mean age of 60.29 ± 13.84 years. In total, 189 patients (50.1%) were treated with trospium (median dose 27.86 ± 12.73 mg), 41 patients (10.9%) with propiverine (28.17 ± 4.97 mg), nine patients (2.4%) with extended-release tolterodine (4.0 ± 0 mg), 48 patients (12.7%) with solifenacin (5.94 ± 1.97 mg) and 90 patients (23.9%) with fesoterodine (6.09 ± 2.01 mg). Results. The median time for persistence with the first line anticholinergic treatment was 6.53 ± 3.84 months. Persistence was significantly higher in patients treated with anticholinergic medication with an extended-release formulation than in patients treated with immediate-release anticholinergics. The most common reasons for termination of treatment were healing/resolution of symptoms (35.9%), low effectiveness (30.9%) and side-effects (23.7%). Conclusions. More than half of the OAB patients were not satisfied with their first line treatment. Other treatment options should be sought, such as changing the medication or dosage, or possibly combining treatments.
