What are three primary effects of Bethanechol?

Bethanechol is a cholinergic agonist, primarily acting on muscarinic receptors, and it has several key therapeutic effects relevant to the question.

The correct response highlights the effects of increased gastrointestinal (GI) motility, detrusor muscle contraction, and urethral sphincter relaxation. Increased GI motility is significant as Bethanechol stimulates the smooth muscle of the gastrointestinal tract, promoting digestion and movement of contents through the intestines. This can be particularly useful in treating conditions like urinary retention or gastrointestinal atony where increased motility is desired.

Detrusor contraction refers to the contraction of the bladder muscle, which is essential for urination. By facilitating the contraction of the detrusor muscle, Bethanechol aids in the emptying of the bladder, making it a valuable treatment for people who cannot effectively urinate due to various conditions.

Urethral sphincter relaxation is crucial as it allows the passage of urine. By relaxing the sphincter, Bethanechol enhances the ability to initiate and maintain urination, which is particularly beneficial in scenarios where sphincter tightness can hinder urinary flow.

Overall, the primary therapeutic actions of Bethanechol – increasing GI motility, promoting detrusor contraction,
