Descripción

Application

Acetyl-β-methylcholine (methacholine), an analog of acetylcholine, is use as a receptor agonist to study processes such as airway hyperresponsiveness associated with asthma.

Biochem/physiol Actions

Metabolically stable analog of acetylcholine; muscarinic agonist. Its ability to constrict airway smooth muscle is used to assess bronchial reactivity in the laboratory and clinically.
