Objectives To evaluate the efficacy and safety of nighttime dosing with tolterodine extended release (TER) in men with overactive bladder (OAB) and nocturia. Methods This was a post hoc analysis of data from two 12-week, double-blind, placebo-controlled trials of nighttime (<4 hours before bedtime) TER (4 mg daily) dosing. Men with a mean micturition frequency of eight or more times in 24 hours, including a mean of 2.5 or more nocturia episodes/night, were included. For each micturition, patients used 7-day diaries to record urinary urgency on a 5-point urgency rating scale (1, none; 2, mild; 3, moderate; 4, severe; 5, urgency urinary incontinence). Micturitions were analyzed post hoc by urgency rating categories: total (1 to 5), non-OAB (1 to 2), OAB (3 to 5), and severe OAB (4 to 5). Adverse events were recorded throughout the study. Results A total of 745 men (mean age 64 years) were randomized to placebo (n = 374) or TER (n = 371). Of the 745 men, 73% reported no incontinence episodes in a 7-day diary at baseline. At week 12, the weekly values for nighttime severe OAB micturitions and 24-hour and daytime total, OAB, and severe OAB micturitions were significantly reduced in the TER group versus the placebo group. The TER-treated men also reported a significant reduction in the mean urgency rating versus placebo. Adverse events associated with TER were low and comparable to those in the placebo group, with the exception of dry mouth (11% versus 4%). Withdrawals because of adverse events were infrequent (3% TER, 4% placebo). Five men were withdrawn for symptoms suggestive of urinary retention (3 TER, 2 placebo). Conclusions Nighttime TER dosing reduced urgency-related micturitions and was well tolerated in men with OAB and nocturia.
