Muscarinic agonists are used to treat overactive bladder, urinary retention, and dry mouth. They also have other uses, such as managing certain gastrointestinal conditions. These medications work by stimulating muscarinic receptors, which helps to increase bladder muscle contractions and saliva production. Muscarinic-agonists come in different forms, including oral pills and topical patches. Examples include solifenacin (Vesicare), tolterodine ER (Detrol LA), and bethanechol (Urecholine). You can choose the form that best fits your needs.
