Product Data Sheet
Methacholine bromide
Catalog No. A61495
Methacholine bromide is a potent agonist of the muscarinic-3 (M3) receptor. Its primary action induces bronchoconstriction by directly stimulating acetylcholine receptors on smooth muscle, resulting in airway narrowing. This compound is particularly sensitive for identifying bronchial hyperresponsiveness (BHR) and is utilized in clinical settings to assess airway hyperresponsiveness (AHR) in patients presenting with asthma-like symptoms, especially those with normal resting expiratory flow rates.
