New Data on Tolterodine: Do Recent Findings Dispel Questions About Treating Overactive Bladder in Men?

Solifenacin treatment in men with overactive bladder: effects on symptoms and patient-reported outcomes

OBJECTIVE

In the few studies to evaluate antimuscarinics for overactive bladder (OAB) in men, safety has been the primary focus. In OAB efficacy trials, subject populations have been predominantly female and patient-reported outcomes (PROs) have been assessed only recently. We present a post hoc analysis of PRO-based findings from the subset of men (without presumed bladder outlet obstruction [BOO]) from two large, independent, open-label trials of solifenacin.

METHODS

Subjects with OAB for > or =3 months received flexibly dosed solifenacin for 12 weeks. At baseline and 4-week intervals, subjects completed the Patient Perception of Bladder Condition (PPBC) and Overactive Bladder Questionnaire (OAB-q). In one study, subjects also completed 3-day bladder diaries. At baseline, mean PPBC scores were similar in both studies and indicative of moderate-to-severe problems.

RESULTS

After 12 weeks of solifenacin, mean PPBC scores improved significantly (p < 0.0001); values were suggestive of minor-to-moderate problems. Mean scores on the OAB-q were also significantly improved after solifenacin (p values < or =0.001). In men without presumed BOO, solifenacin significantly improved PRO measures of symptom bother, health-related quality of life, and overall perception of bladder problems.

CONCLUSION

Results from these two studies support the use of solifenacin as a well-tolerated and efficacious treatment option for providing symptom relief in men with OAB without BOO.
