Description

Mepenzolate is a post-ganglionic parasympathetic inhibitor. It decreases gastric acid and pepsin secretion and suppresses spontaneous contractions of the colon. Mepenzolate diminishes gastric acid and pepsin secretion. Mepenzolate also suppresses spontaneous contractions of the colon. Pharmacologically, it is a post-ganglionic parasympathetic inhibitor. It has not been shown to be effective in contributing to the healing of peptic ulcer, decreasing the rate of recurrence, or preventing complications.

Indication

For use as adjunctive therapy in the treatment of peptic ulcer. It has not been
shown to be effective in contributing to the healing of peptic ulcer, decreasing the rate of recurrence, or preventing complications.

Pharmacology

Mepenzolate diminishes gastric acid and pepsin secretion. Mepenzolate also suppresses spontaneous contractions of the colon. Pharmacologically, it is a post-ganglionic parasympathetic inhibitor.

Toxicity

The signs and symptoms of overdosage are headache; nausea; vomiting; blurred vision; dilated pupils; hot, dry skin; dizziness; dryness of the mouth; difficulty in swallowing; and CNS stimulation. A curare-like action may occur (i.e., neuromuscular blockade leading to muscular weakness and possible
paralysis). The oral LD₅₀ is greater than 750 mg/kg in mice and greater than 1000 mg/kg in rats.

Affected Organisms

Absorption

Between 3 and 22% of an orally administered dose is excreted in the urine over a 5-day period, with the majority of the radioactivity appearing on Day 1. The remainder appears in the next 5 days in the feces and presumably has not been absorbed.

Elimination

Between 3 and 22% of an orally administered dose is excreted in the urine over a 5-day period, with the majority of the radioactivity appearing on Day 1.
