Changes in remnant-like particle cholesterol level during treatment of hypertension with amlodipine and cilnidipine

Abstract

This study was designed to determine the effect of antihypertensive agents (calcium channel blockers) on the levels of remnant-like particle (RLP) cholesterol; a major risk factor for coronary heart disease, during treatment of hypertension.

Thirty six hypertensive patients of both sexes were selected into this study. Twenty-five of them were treated with amlodipine while eleven patients were treated with cilnidipine all for 3 months. At the beginning and after 3 months of treatment, serum RLP-cholesterol levels were measured in the two treatment groups. RLP-cholesterol level was significantly reduced after clinidipine treatment while the reduction in RLP-cholesterol level after amlodipine treatment was not statistically significant. Our findings show that calcium channel blockers may lower the risk of myocardial infarction, coronary atherosclerosis and/or coronary thrombus formation through reduction in RLP-cholesterol levels during antihypertensive pharmacotherapy.

Key Words: RLP-cholesterol, amlodipine, cilnidipine, hypertension treatment.
