Combination Treatment With Doxazosin Plus TolterodineSR 2 mg Versus 4mg in Men With an Overactive Bladder (OAB) and Benign Prostatic Hyperplasia (BPH)

Overactive Bladder Clinical Trial

Official title:
Comparison of the Efficacy and Safety of Combination Treatment With Doxazosin Plus TolterodineSR 2 mg vs Doxazosin Plus TolterodineSR 4 mg in Men With an OAB/BPO: Randomized Controlled Study"

Clinical Trial Summary

OAB occurs in approximately 50% to 75% of men with BPO and up to 38% of men with BPO continue to suffer from OAB after relief the obstruction.Symptoms of OAB are more bothersome than the voiding complaints of slow stream and hesitancy. However, the patients with both BPO and OAB are often not treated with muscarinic receptor antagonists due to concern that they will experience acute urinary retention.

Tolterodine is a potent and pure muscarinic receptor antagonist that was developed specifically for the treatment of overactive bladder. Recently, studies revealed that tolterodine was effective, safe and well tolerated in adults with OAB and urodynamically confirmed BPO.However, the optimal dosage of antimuscarinic for the treatment of OAB coexisting BPO was not yet fully assessed. In real clinical situation, some patients complain voiding difficulty after addition of antimuscarinics and want to stop antimuscarinics.It is probable that a lower dosage of antimuscarinics combined with alpha-adrenergic antagonists can be used safely in OAB patients with BOO, with the same efficacy.

This study is designed to investigate the optimal doses of tolterodine SR in combination with doxazosin in men with both BOO and OAB based on efficacy, safety, and tolerability.
