【化学名】 5-〔(3,4-二甲氧基苯乙基)甲胺基〕-2-(3,4-二甲氧基苯基)-2-异丙基戊腈盐酸盐【作用特点】本品为罂粟碱的衍生物,是一种抑制β-受体的冠状动脉扩张剂。其抗心律失常作用与奎尼丁相似,能增加冠状动脉血流量,降低周围循环阻力,从而减轻心脏负荷,降低心肌耗氧量,延长心房不应期,抑制心肌自律性及减慢房室传导的作用,因而适用于治疗室上性心律失常。同时尚可改善
[Chemical name] 5 - [(3,4-dimethoxyphenethyl) methylamino] -2- (3,4-dimethoxyphenyl) -2-isopropylpentanenitrile hydrochloride 【Features】 This product is papaverine derivatives, is a β-receptor inhibiting coronary dilating agent. Its anti-arrhythmic effect similar to quinidine, can increase coronary blood flow, reduce peripheral resistance, thereby reducing the heart load, reduce myocardial oxygen consumption, prolongation of atrial refractory period, inhibition of myocardial self-discipline and slow atrioventricular conduction Therefore, it is suitable for the treatment of supraventricular arrhythmias. At the same time can be improved
