Cevimeline hydrochloride is?

• A. A beta-adrenergic agonist
• B. A muscarinic antagonist
• C. A nicotinic antagonist
• D. A muscarinic cholinergic agonist

Answer: (D)

Cevimeline hydrochloride acts as a muscarinic cholinergic agonist, meaning it mimics acetylcholine at muscarinic receptors. Stimulating these receptors, especially the M3 subtype on salivary glands, increases glandular secretion, which helps relieve dry mouth in conditions like Sjögren’s syndrome. It is not a beta-adrenergic agonist, which would target adrenergic receptors with different systemic effects. It isn’t a nicotinic antagonist or a muscarinic antagonist, which would block receptor activity rather than stimulate it. So the best description is that cevimeline is a muscarinic cholinergic agonist.
