摘要: 目的和方法 复方盐酸伪麻黄碱溶液由盐酸伪麻黄碱、氢溴酸右美沙芬和扑尔敏组成的止咳平喘口服溶液, 本实验研究它们对组胺所致离体豚鼠气管平滑肌收缩的协同平喘作用。结果和结论 扑尔敏对气管平滑肌H1 有竞争拮抗作用, 盐酸伪麻黄碱表现为非竞争拮抗作用, 虽然氢溴酸右美沙芬本身没有明显拮抗作用, 但三个药合用产生了协同平喘作用。协同作用表现在扑尔敏和盐酸伪麻黄碱之间, 扑尔敏和氢溴酸右美沙芬之间。三个药合用可产生最明显的协同平喘作用。

Abstract: Aim & Methods The effect of pseudoephedrine hydrochloride mixture, a compound consisting of pseudoephedring hydrochloride, dextromethorphan hydrobromide and chlorpheniramine, on the histamine-induced cont raction of guinea pig bronchial smooth muscle was studied in vitro by the method of receptor kinetics.Results & Discussion The result showed that H1 receptor of histamine in isolated bronchial smooth muscle was competitively blocked by chlorpheniramine and noncompetitively blocked by pseudoephedring hydrochloride. Though the significant antagonism on the H1 receptor was not observed with dextrome hydrobromide alone, synergetic asthma-relieving effects were shown as the medicine was simultaneously administ rated with pseudoephedring hydrochloride or chlorpheniramine.furthermore, when these three drugs were simultaneously administ rated, the most obvious synergetic could be observed.

Key words: pseudoephedrine hydrochloride mixture, trachea, guinea pig
