Bethanechol is a cholinergic agent primarily used to treat urinary retention due to surgery, childbirth, or bladder muscle dysfunction. It works by stimulating the detrusor muscle of the bladder, promoting urination and relieving retention. Its clinical relevance lies in its ability to enhance bladder contractility and improve urinary flow, making it a valuable option for patients with urinary retention. In summary, Bethanechol effectively facilitates urination by acting on bladder muscles.
Bethanechol stimulates muscarinic receptors in the bladder detrusor muscle, leading to contraction and increased urinary flow.
