Overactive Bladder in Children Medication

Medication Summary
Although pharmacologic therapy is one of the mainstays in the treatment of adult overactive bladder (OAB) and the management of neurogenic detrusor overactivity, its role in the treatment of idiopathic OAB in children is less well defined.
Anticholinergic agents are often used in children with OAB when behavioral therapy has failed or as an adjunct to behavioral therapy. Currently, the most commonly used anticholinergic for the treatment of OAB in children is oxybutynin (Ditropan XL).
Other agents used in the treatment of adult OAB have been used in children. Tolterodine (Detrol), a nonselective antimuscarinic agent with a favorable tolerability profile compared with oxybutynin, has been studied in children. However, no pediatric indication is listed in the labeling. Trospium chloride (Sanctura), another agent used in adults, has been used in a small series of children, with doses varying from 10-25 mg/d, divided bid.
Other newer anticholinergic agents used in adult patients with OAB that have not been studied in children include solifenacin (Vesicare) and darifenacin (Enablex).
Anticholinergic Agents
Class Summary
Anticholinergic agents inhibit the binding of acetylcholine to the cholinergic receptor, thereby suppressing involuntary bladder contraction of any etiology. In addition, they increase the volume of the first involuntary bladder contraction, decrease the amplitude of the involuntary bladder contraction, and may increase bladder capacity.
Oxybutynin (Ditropan, Ditropan XL, Oxytrol, Gelnique)
Oxybutynin inhibits the action of acetylcholine on smooth muscle and has a direct antispasmodic effect on smooth muscles, increasing bladder capacity and decreasing uninhibited contractions.
