摘要: 目的 研究班布特罗对豚鼠实验性哮喘的作用、药效学及药动学特点及作用机制。方法 组胺和卵清蛋白诱发在体豚鼠实验性哮喘模型, 使用豚鼠离体气管片和肺条进行研究。结果 班布特罗剂量依赖性抑制组胺和卵清蛋白诱发的豚鼠哮喘, 班布特罗对豚鼠气管片无松弛作用, 而灌服其后的松弛气管片和肺条血浆呈剂量依赖性, 且对肺条的松弛作用强于气管片。其峰效应出现于给药后4 h 前后, 作用持续24 h 以上。结论 班布特罗作为特布他林的前药对豚鼠实验性哮喘的作用缓和而持久。

Abstract: Aim To probe the effect of bambuterol on experimental asthma and its pharmacody namic and pharmacokinetic chracteristics, as w ell as its mechanism. Methods Experimental asthma model on guinea pigs was induced by histamine and ovalbumin in vivo and their t rachea f lake and pulmonary bar were emptied to the research in vi tro respectively.Results Bambuterol inhibited asthma induced by histamine and ovalbumin in guinea pigs in a dose-dependent manner. Bambuterol gave no relaxation to all t rachea f lake, but the int ragast ric gavage (ig) of plasma of the bambuterol-treated g uinea pig s relaxed t rachea f lake and pulmonary bar, and the effect on pulmonary bar was st ronger than that on t rachea f lake.The peak value appeared about 4 h after administration, and the action continued for more than 24 h.Conclusion Bambuterol as pro-drug of terbutaline metabolized in body has a mild and permanent effect on the model of experimental asthma in g uinea pig s.
