本文着重讨论正性肌力作用药物及外周血管扩张药。选材的标准是一药或一类药的临床实用性,新药的潜在临床实用性。以及具有独特作用和可能有益机理的药物。强心甙在美国估计有200万病人,英国至少有50万病人,德国有400万人服过强心甙。强心甙的作用机理很复杂,向有争议。最近报道,强心甙剂量高于10~(-8)M 时抑制肌浆膜Na~+,K~+- This article focuses on inotropic agents and peripheral vasodilators. The selection criteria are the clinical utility of a drug or class of drugs and the potential clinical utility of a new drug. As well as drugs that have unique and potentially beneficial mechanisms. Cardiac glycosides are estimated at 2 million in the United States, at least 500,000 in the United Kingdom and over 4 million in Germany. The mechanism of action of cardiac glycosides is complex and controversial. Recently reported that cardiac glycosides dose higher than 10 ~ (-8) M inhibition of sarcoplasmic membrane Na ~ +, K ~ + -
