与生理盐水相比,等渗镁对醋甲胆碱及组胺引起的支气管狭窄具有抑制作用,且血清镁水平持久增加可通过β２受体亲和力的增加而增强沙丁胺醇的支气管扩张作用。本研究的目的是测定等渗镁作为雾化沙丁胺醇的赋形剂是
Compared with normal saline, isotonic magnesium inhibits methacholine and histamine-induced bronchoconstriction, and prolonged serum magnesium levels enhance the bronchodilator effect of salbutamol through an increase in β2 receptor affinity. The purpose of this study was to determine isotonic magnesium as an excipient of nebulized albuterol
