本文就有关血管扩张剂、冠状动脉扩张剂、脑循环促进剂、降脂药、β-受体阻断剂、毛细血管强化剂、血管收缩中主要的一些药物在体内的代谢作一概述。一、血管扩张剂治疗心绞痛的亚硝酸类制剂具有能直接松弛小动脉、毛细血管以及小静脉的平滑肌、增加血流量,并有扩张冠状动脉而增加冠脉血流量的作用。 This article summarizes the in vivo metabolism of some of the major drugs used in vasodilators, coronary dilators, cerebral circulation promoters, lipid-lowering drugs, beta-blockers, telangiectasics, and vasoconstriction. First, vasodilators for the treatment of angina nitrite preparations can directly relax the arterioles, capillaries and venules of the smooth muscle, increase blood flow, and the expansion of coronary artery and increase coronary blood flow.
