A double-blind comparison of the effects of carvedilol and captopril on serum lipid concentrations in patients with mild to moderate essential hypertension and dyslipidaemia.
European journal of clinical pharmacology(1993)
摘要
We have studied 250 patients with mild to moderate essential hypertension (diastolic blood pressure 95-114 mmHg) and dyslipidaemia (high-density lipoprotein cholesterol (HDL-C) below 1.03 mmol.l-1, total cholesterol 5.17-9.05 mmol.l-1, and triglycerides 2.26-5.64 mmol.l-1) in a controlled double-blind, multicentre, parallel group trial. The patients took a fat-modified diet. After a 4-week placebo period, patients who continued to fulfil the selection criteria were randomly allocated to treatment with either carvedilol (a vasodilating beta-blocker) 25-50 mg o.d. (n = 116) or captopril (an ACE inhibitor) 25-50 mg o.d. (n = 117) for 6 months. In both groups there were favourable effects on the serum lipids. The relative changes (medians) in the carvedilol and captopril group were respectively: increase in HDL-C by 11% and 8%, decrease in total cholesterol by 11% and 10%, in low-density lipoprotein cholesterol by 16% and 12%, and in triglycerides by 13% and 14%. Equivalence of the two treatments was confirmed for the target variable change in HDL-C at a significance level of 5%. Reductions in supine systolic/diastolic blood pressures were comparable in the two groups (carvedilol: 23/19 mmHg, captopril: 20/18 mmHg). The improvement in lipid metabolism in patients treated with carvedilol is probably due to its alpha 1-blocking properties.
