Mepenzolate is an antimuscarinic medication primarily used to treat peptic ulcers by reducing stomach acid secretion.

[1] Mepenzolate works by blocking the action of acetylcholine on muscarinic receptors in the gastrointestinal tract.

This action reduces the secretion of stomach acid and slows intestinal motility, making it useful in the management of peptic ulcers and other gastrointestinal disorders.

Common side effects of Mepenzolate include dry mouth, blurred vision, constipation, and urinary retention.

These side effects are typical of antimuscarinic agents due to their action on muscarinic receptors throughout the body.
