A study in the November 15 Journal of the American Medical Association finds that a combination of two drugs--tolterodine (Detrol LA), which is used to treat urinary problems, and tamsulosin (Flomax), which is used to treat BPH symptoms--shows real benefit for treating men with overactive bladder.
In addition to Sanctura and oxybutynin--available as Ditropan and in generic formulations and as extended release oxybutynin (Ditropan XL)--the other anticholinergics approved for OAB are regular and long-acting tolterodine (Detrol and Detrol LA) and the oxybutynin transdermal patch (Oxytrol).
A study compared the two most commonly used drugs for overactive bladder, extended-release oxybutynin (Ditropan XL) and extended-release tolterodine (Detrol LA), in 790 women with urinary incontinence.
Drug Dosage Cost/Day oxybutynin 5-15 mg/day, $3.05 * (Ditropan XL) once daily (10 mg/day) tolterodine 2-4 mg/day $2.95 * (Detrol LA) once daily (4 mg/day) oxybutynin 3.9 mg/day $2.34 ** transdermal system (Oxytrol) oxybutynin 5 mg, three to $1.38 * four times (15 mg/day) daily imipramine 10-150 $1.74 * mg/day, three (75 mg/day) times daily Drug Comment[dagger] oxybutynin Extended-release formulation.
One limitation of this meta-analysis is that it did not include long-acting oxybutynin (Ditropan XL) or tolterodine (Detrol LA), which may be better tolerated.
