Overactive Bladder

Brief summary

To evaluate the effect of fesoterodine on patient satisfaction and overactive bladder (OAB) symptom relief in OAB patients who were dissatisfied with their prior therapy with tolterodine.

Interventions

12 weeks of study treatment: Subjects received fesoterodine tablets 4 mg once daily for 4 weeks; thereafter, daily dosage was maintained at 4 mg or increased to 8 mg based on subject's and physician's subjective assessment of efficacy and tolerability.

Mean Number of Micturition Episodes Per 24 HoursBaseline and Week 12The mean number of micturitions per 24 hours is calculated as the total number of micturitions divided by the total number of diary days collected at that visit.
Mean Number of Urgency Urinary Incontinence (UUI) Episodes Per 24 HoursBaseline and Week 12The mean number of UUI episodes per 24 hours is calculated as the total number of micturitions with Bladder Sensation Scale (BSS) = 5 divided by the total number of diary days collected at that visit. BSS: 5 point scale measuring need to urinate from 1=no urgency to 5=unable to hold; leak urine.
