  • Title: Mechanism of differential effects of antihypertensive agents on serum lipids.
    Author: Brook RD.
    Journal: Curr Hypertens Rep; 2000 Aug; 2(4):370-7. PubMed ID: 10981172.
    Abstract:
    Essential hypertension is frequently associated with the metabolic abnormalities of insulin resistance and dyslipidemia. This prevalent clustering of multiple cardiovascular risk factors may help explain the less-than-expected improvement in coronary heart disease mortality provided by simple blood pressure reduction alone. Many antihypertensive medications effectively reduce blood pressure while providing no benefit or even causing a detrimental effect on the associated metabolic abnormalities. beta-Blockers and diuretics tend to negatively affect both glucose tolerance and plasma lipids. Calcium channel blockers, angiotensin converting enzyme inhibitors, and angiotensin II receptor blockers are most often found to be metabolically neutral. alpha-Blockers provide the most favorable metabolic effects of antihypertensive agents by improving both insulin sensitivity and dyslipidemia. The multiple physiologic mechanisms by which blood pressure medications alter plasma lipids are discussed in detail. The effects of antihypertensive medications on postprandial lipid metabolism and the associated postprandial lipemia-induced endothelial dysfunction deserve special attention.
