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.
The chemical structure of Mepenzolate is characterized by the presence of a piperidyl group attached to a benzilate moiety, with an additional methyl group. This structure is similar to that of N-Methyl-3-piperidyl benzilate, but with a methylation that enhances its antimuscarinic properties.
Mepenzolate is primarily indicated for the treatment of peptic ulcers. It may also be used off-label for other conditions where reduction of gastrointestinal motility and secretion is desired.
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.
