How does Oxybutynin work?
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 oxybutynin helps calm bladder muscle contractions that are too frequent and uncontrollable, it can help relieve many associated symptoms.
