antimuscarinic

Full Definition

Type of anticholinergic drug that specifically blocks muscarinic acetylcholine receptors, causing effects such as dry mouth, constipation, urinary retention, and cognitive impairment. In psychopharmacology, many psychiatric medications have antimuscarinic properties as side effects, including tricyclic antidepressants, some antipsychotics, and antihistamines. Editors should understand that antimuscarinic is a subset of anticholinergic effects, specifically targeting muscarinic (not nicotinic) receptors.

Usage

Usage note: More specific than 'anticholinergic' - refers specifically to muscarinic receptor blockade.
