Objective: To evaluate the long-term effects of tolterodine on the health-related quality of life (HRQoL) of patients diagnosed with overactive bladder with incontinence., Methods: Patients who completed a 12-week randomized, double-blind, safety and efficacy trial comparing tolterodine with placebo were invited to enroll in a 12-month open-label continuation trial to assess the long-term safety and efficacy of tolterodine. This study reports the HRQoL results from the King's Health Questionnaire (KHQ) and the Short Form-36 (SF-36) that were administered at baseline, at the end of the 12-week trial, and 3 and 12 months following open-label treatment with tolterodine., Results: One thousand seventy-seven patients were included in the intent-to-treat (ITT(B)) population. KHQ translations were available for 838 patients (mean age, 61.1 years; 80.9% women) in the ITT(B) population. HRQoL, as measured by the KHQ, significantly improved from baseline to months 3 and 12 on the following domains: incontinence impact, role limitations, physical limitations, social limitations, personal relationships, emotions, sleep and energy, severity (coping) measures, and symptom severity. Improvements were generally consistent across all analyses for the 3- and 12-month measurements and for the ITT(B) and completer (C(B)) populations. Patients receiving tolterodine in the double-blind study showed additional improvement at the 3-month open-label assessment on all but the general health domain. At 12 months from treatment rollover, all improvements from rollover to 3 months were sustained with additional improvement seen on the incontinence impact and role limitations domains. The general health perceptions domain showed a slight decline from rollover that might be attributable to a natural decline in patients' health status at this life stage. These findings were consistent with other efficacy results whereby efficacy was maintained over the 12-month open-label period. SF-36 results were consistent with previous experience of reduced sensitivity, as population groups were similar to the SF-36 Physical Component and Mental Component scores at various time points and with all populations., Conclusion: Continued treatment with tolterodine provides additional benefits in HRQoL as measured by the KHQ. Of particular importance are improvements on the psychological aspects after longer-term treatment not detected after a short-term trial. Treatment effects on HRQoL are evident even after a 12-week placebo run-in supporting the true clinical effect of active treatment.

Objective: To compare the health-related quality of life (HRQoL) of overactive bladder (OAB) patients foilowing treatment with tolterodine extended-release (ER) 4 mg once daily versus placebo., Study Design: Multinational, placebo-controlled, randomized, double-blind 12-week study., Population: Patients with urinary frequency ( > or = 8 micturitions/24 hours over a 7-day period), urge incontinence ( > or = 5 episodes/week), and symptoms of OAB for at least 6 months were eligible for inclusion. Patients (81% female) received oral therapy with tolterodine ER (n = 507) or placebo (n = 508) for 12 weeks., Outcomes Measured: HRQoL was assessed using the King's Health Questionnaire (KHQ) and Medical Outcomes Study Short Form 36-item questionnaire (SF-36). Patients also rated their bladder condition. Assessments were performed at baseline and at the end of treatment., Results: At end of treatment, KHQ domains selected a priori as primary HRQoL end points (incontinence impact and role limitations) significantly improved (P < or = .001) with tolterodine ER. Domains selected a priori as secondary end points (physical limitations, sleep and energy, severity [coping] measures, and symptom severity) were also significantly improved (P < or = .006) following treatment with tolterodine ER. The tolterodine ER group had decreased symptom severity and statistically significant improvements in patient rating of bladder control compared with the placebo group at end of treatment. No treatment differences were detected using the SF-36., Conclusion: Many aspects of HRQoL, as measured by the KHQ, showed statistically significant improvement following treatment with tolterodine ER. These HRQoL improvements were consistent with clinical efficacy benefits. Patients receiving tolterodine ER experienced overall improvement in their condition that was associated with an important impact on their HRQoL.
