Methacholine iodide
Based on 6 publication(s) in Google Scholar
Methacholine iodide is a potent muscarinic-3 (M3) agonist. Methacholine iodide acts directly on acetylcholine receptors on smooth muscle causing bronchoconstriction and airway narrowing. Methacholine iodide shows a high sensitivity to identify bronchial hyperresponsiveness (BHR). Methacholine iodide can be 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.
