Oxybutynin belongs to a group of drugs known as antimuscarinic or anticholinergic medications. It works to treat bladder problems by blocking specific receptors in the bladder, called muscarinic receptors, which helps the muscles of the bladder to relax. Since an overactive bladder is often due to muscle contractions that are too frequent and uncontrollable, oxybutynin can help relieve many associated symptoms.
