TL;DRAbstract

This is a prospective study of 28 patients who had urinary frequency (>8 times/day) and either urgency or urge incontinence (>1 time/day). After a 2-week run-in period (visit 1), the patients were started on tolterodine 1 mg twice a day (bid) (visit 2). They were followed at 4 and 8 weeks (visits 3 and 4). The patients were contacted by telephone 1 week after visit 2. Tolterodine was increased to 2 mg bid if the patient had incomplete improvement at either the initial phone call or during visit 3. Evaluation criteria were daily micturition charts including urinary frequency, nocturia, leakage episodes, average urine volume per day, and average voided volume. Tolterodine was well tolerated without side effects in 20 (80%) of 28 patients. Eight patients (20%) dropped out after enrollment because of side effects in 3, no improvement in 2, and missing visits (>1) in 3. Drug dosage in the 20 patients who tolerated tolterodine was 1 mg bid in 3 and 2 mg bid in 17 (85%). According to micturit
