Description

Methacholine chloride is a potent muscarinic receptor agonist[1]. Methacholine chloride acts directly on acetylcholine receptors on smooth muscle, resulting in bronchoconstriction and airway narrowing[2, 3]. Methacholine chloride can be used to measure airway hyperresponsiveness (AHR) as a diagnostic aid in evaluating individuals with asthma-like symptoms and normal resting expiratory flow rates[4, 5].

In vivo, Methacholine chloride (0.5mg/kg) induced bronchoconstriction in male Balb c mice by intravenous injection[6].

Methacholine chloride是一种有效的毒蕈碱受体激动剂[1]。Methacholine chloride能够直接作用于平滑肌上的乙酰胆碱受体,导致支气管收缩和气道变窄[2, 3]。Methacholine chloride能够用于测量气道高反应性(AHR),作为评估具有哮喘样症状和正常静息呼气流速的个体的诊断辅助[4, 5]

在体内,Methacholine chloride(0.5mg/kg)通过静脉注射处理雄性Balb c小鼠,诱导了小鼠支气管收缩[6]
