OBJECTIVE To examine the efficacy of tolterodine, an antimuscarinic agent with a bladder‐selective profile, in patients with mixed incontinence (MI, stress and urge) compared with patients with urge incontinence (UI) alone. PATIENTS AND METHODS The study included 239 patients with MI (urge predominating) and 755 with urge incontinence alone from a single‐blind, multicentre trial of 1380 patients (80% female) with an overactive bladder. Those completing the trial were analysed ‘per‐protocol’. After a 7‐day washout and a 3‐day run‐in to collect baseline information, patients were treated with tolterodine twice daily for 16 weeks. The two groups were compared for incontinence episodes/24 h, voiding frequency, nocturia episodes and pad usage after 16 weeks of treatment. RESULTS After 16 weeks the median changes from baseline for all voiding variables were statistically significant for the MI and the UI groups ( P < 0.001), with no apparent significant between‐group differences. The median percentage reduction in incontinence episodes from baseline was 67% for the MI and 75% for the UI groups ( P = 0.39). ‘Dry’ rates for the MI and UI groups at the end of the study were 39% (66/171) and 44% (243/552), respectively, whilst 24% of patients in each group (MI 40/170; UI 130/551) achieved a voiding pattern of < 8 voids/24 h. ‘Cure’ rates for nocturia and the reduction in the number of patients not using pads used were also similar between the groups. CONCLUSION Tolterodine is as effective in reducing leakage and other symptoms of an overactive bladder in patients with MI as it is in patients with UI alone.
