【化学名】 4-氨基-2-[4-(2-呋喃甲酰基)-1-哌嗪基]-6,7-二甲氧基喹唑啉盐酸盐【结构式】【作用特点】本品是一种新型的口服血管扩张药。属于喹啉衍生物。本品能选择性地阻当突触后α-肾上腺素能受体,因而使周围小动脉血管舒张而达到降压效果。动物实验表明它直接舒张血管平滑肌并阻断α-肾上腺素能受体,减少外周围血管阻力而降低 【Chemical Name】 4-Amino-2- [4- (2-furoyl) -1-piperazinyl] -6,7-dimethoxyquinazoline hydrochloride 【Structure】 【Features】 本 本Product is a new type of oral vasodilator. Belongs to quinoline derivatives. This product can selectively block the post-synaptic α-adrenergic receptor, thus enabling peripheral arteriolar vasodilatation and achieve antihypertensive effect. Animal experiments show that it directly relax the vascular smooth muscle and block the α-adrenergic receptor, reduce peripheral vascular resistance and reduce
