Abstract

Dose-response curves of the effect of angiotensin I (A-I) infusion on diastolic blood pressure were constructed before and 3 h following single oral doses of the angiotensin-converting enzyme (ACE) inhibitor cilazapril (1.25 to 30 mg) in six normal male subjects. Cilazapril shifted the A-I dose-response curves dose dependently rightward; Schild-plot analysis indicated a competitive antagonism by cilazapril with an apparent Ki-dose of about 0.6 mg.

摘要

在6名正常男性受试者中,分别于单次口服血管紧张素转换酶(ACE)抑制剂西拉普利(1.25至30毫克)之前及之后3小时,构建了输注血管紧张素I(A-I)对舒张压影响的剂量-反应曲线。西拉普利使A-I剂量-反应曲线剂量依赖性地向右移动;希尔德分析表明西拉普利具有竞争性拮抗作用,其表观Ki剂量约为0.6毫克。
