Application

Telenzepine dihydrochloride hydrate was used to study M1 muscarinic receptor-mediated signaling in juvenile rat hippocampus and rat urinary bladder.

Biochem/physiol Actions

Telenzepine is an analog of pirenzepine and inhibits the secretion of gastric acid. It is an antagonist to M1-receptor and targets the oxyntic gastric glands and the salivary glands.
