Persistence with antimuscarinic therapy in patients with overactive bladder.

Overactive bladder (OAB) is a chronic condition, which impacts patients' health and quality of life. The primary symptoms of OAB are distressing and may interfere with work, psychosocial and sexual functioning. OAB also is associated with increased risk of urinary tract infections, fractures from falls, skin infections and depression. Patient's concerns about the effects of incontinence on lifestyle highlight the need to restore continence. The mainstay of treatment is antimuscarinic drug therapy, which may often produce only modest reductions in OAB symptoms and may be accompanied by bothersome adverse effects, leading to poor adherence to prescribed medications. Successful treatment of OAB depends on persistence with the prescribed medication, and efficacy and tolerability are key influencers of persistence. New antimuscarinic agents are now available for treating OAB that significantly improve symptoms of incontinence, urgency and frequency with few adverse effects. An improved efficacy and tolerability profile should result in greater patient satisfaction and persistence with therapy during long-term therapy.
