| Biological Activity | Methacholine (Acetyl-β-methylcholine) chloride acts a muscarinic M3 receptor agonist in the parasympathetic nervous system. Methacholine chloride acts directly on acetylcholine receptors on smooth muscle causing contraction and airway narrowing. Methacholine challenges are widely used to measure airway hyperresponsiveness (AHR) as a diagnostic aid in the assessment of individuals with asthma-like symptoms and normal resting expiratory flow rates[1][2][3]. |
