HIDE SMILES / InChI
Mepenzolate is a postganglionic parasympathetic inhibitor. It decreases gastric acid and pepsin secretion and suppresses spontaneous contractions of the colon. It specifically antagonizes muscarinic receptors. Mepenzolate is marketed under the brand name CANTIL. CANTIL is indicated 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.

CNS Activity

Curator's Comment: Similar to other quaternary ammonium anticholinergics, mepenzolate has limited ability to cross lipid membranes, such as the blood-brain barrier.
