沙甲喘宁(S)是一种新的β_2-肾上腺素能受体促效剂,是支气管扩张剂舒喘宁的一种化学类似物。两种药物的结构相似,不同的是沙甲喘宁有一条细长的侧链,通过此侧链使药物分子牢固地结合到β_2-肾上腺素能受体蛋白区,保持固定在该部位并与受体反复接触,从而使药物作用时间延长。本文作者对沙甲喘宁与舒喘宁治疗轻至中度哮喘的作用进行了比较。病人和方法选择234例无吸烟的哮喘病
Salmeterol (S) is a new β 2 -adrenoceptor agonist and is a chemical analog of bronchodilator albuterol. The structures of the two drugs are similar, except that sodiacene has a slender side chain through which the drug molecule binds strongly to the β_2-adrenergic receptor protein region, remains immobilized at that site and Repeated exposure of the receptor, so that the role of drugs to extend the time. The authors compared the effects of shatrazin and salbutamol on mild-to-moderate asthma. Patients and Methods Two hundred and thirty-four non-smokers with asthma were selected
