Part of speech: noun

Definitions

1. A synthetic compound used medically to stimulate muscle contractions in the bladder and gastrointestinal tract ; a drug employed to treat urinary retention and to enhance digestive motility ; a cholinergic agent that mimics the effect of acetylcholine to promote parasympathetic nervous system activity
2. A pharmaceutical substance that triggers smooth muscle activation in the urinary and digestive systems ; a medication intended to alleviate difficulty in urination and promote bowel movement ; a chemical that acts on muscarinic receptors to increase parasympathetic responses
3. A man-made drug designed to facilitate bladder emptying and gastrointestinal peristalsis ; a therapeutic compound used for managing impaired bladder and digestive functions ; a muscarinic receptor agonist that encourages bodily functions associated with rest and digestion

Etymology: Bethanechol is a name built from its chemical structure rather than coined for a person or event. Its parts are "beta-methyl," "urethane," and "choline." Choline is the base of acetylcholine, the nerve signalling chemical that switches on muscle contraction, and the drug was designed to act like it. The "urethane" portion points to a carbamate group, a chemical family whose name also gives the urinary tract its link, since the drug's main targets are the bladder and gut. The name therefore records a chemist's blueprint: a methyl group attached at the beta position of a choline-like molecule, combined with a urethane-type structure. Because the drug acts on the parasympathetic nervous system, the name works as a compact description of what it is made of and what it imitates. It is a pure technical coinage, so there is no older everyday sense to trace.
