How Does Oxybutynin ER Work?
Oxybutynin ER belongs to a group of medications known as anticholinergics or antimuscarinics. It works by binding to specific receptors (called muscarinic receptors) in the bladder, helping to relax the muscles of the bladder. Since an overactive bladder is often due to bladder muscle contractions that are too frequent and uncontrollable, oxybutynin ER can help relieve many of the symptoms of an overactive bladder.
