心得舒是一个β-阻断剂类的心血管药,其化学名为1-(邻-丙烯基苯氧)-3-异丙氨基丙醇-[2]-盐酸盐(英国与瑞典的商品名有:Alprenolol和Aptin),能强烈地抑制由于交感神经过度刺激而引起的心脏异常兴奋,不使心脏机能过于低下而维持在正常范围内。因而适用于室上性心动过速、期外收缩等症,对心绞痛也有一定疗效。本品并能减低心脏负荷、调整心肌需氧平衡,从而改善由于上述疾病引起的胸痛和胸部压缩感等。而对于正常范围的心跳与心肌收缩等不产生影响。本品特点是:在消化道吸收良好,在体内代谢迅速而无蓄积作用。药物能在24小时内作为代谢物从尿中排出,毒性低、副作用小。但对严重心力衰竭和房室阻滞(Ⅱ、Ⅲ度)、支气管哮喘以及代谢性酸中毒患者则忌用。
Insulin is a beta-blocker cardiovascular drug whose chemical name is 1- (o-propenylphenoxy) -3-isopropylaminopropanol- [2] -hydrochloride (British and Swedish Under the trade names of Alprenolol and Aptin) can strongly inhibit the abnormal excitement of the heart due to sympathetic over-stimulation without maintaining the heart function excessively low and maintaining the normal range.
