支气管哮喘(简称哮喘)的发病机制非常复杂,至今尚未完全阐明,但近年来由于气道学说的建立,以及免疫与变态反应学说,气道神经调节机制,遗传机制等的深入研究,人们对哮喘已有了更进一步的了解。1哮喘的常用治疗药物~([1])1.1β-肾上腺素受体激动剂包括非选择性的β_2-肾上腺素受体激动剂如肾上腺素、麻黄碱和异丙肾上腺索以及选择性β_2-肾上腺素受体激动剂如沙丁醇胺、叔丁喘宁等。它们主要通过激动呼吸道的β_2受体激活腺苷酸环化酶,使细胞内的环
The pathogenesis of bronchial asthma (asthma) is very complicated and has not yet been fully elucidated, but in recent years due to the establishment of airway theory, as well as the immune and allergic theory, airway neuromodulation mechanisms, genetic mechanisms and other in-depth study of asthma Have a better understanding. 1 Commonly Used Agents for Asthma ~ ([1]) 1.1 Beta-adrenergic receptor agonists include nonselective beta 2-adrenergic receptor agonists such as epinephrine, ephedrine and isoproterenol and selectively beta 2-adrenergic receptors Adrenergic receptor agonists such as albuterol, terbutaline, and the like. They activate adenylate cyclase mainly by agonizing the beta 2 receptor of the respiratory tract, causing intracellular loops
