Pleiotropic Effects of ARB on Dyslipidemia

Angiotensin II type 1 (AT1) receptor blockers (ARBs), widely used in the treatment of hypertension, have cardiovascular, cerebral, and renal protective effects beyond blood pressure control. In addition to direct end-organ protection, some ARBs have been suggested to improve abnormalities of glucose and lipid metabolisms, resulting in an anti-atherosclerotic effect in patients with hypertension. In several clinical trials, the effects of ARBs on lipid metabolism have been emerged, although the effects are heterogeneous. Certain subgroups of ARBs such as telmisartan have been identified as partial agonists for the peroxisome proliferators activated receptor (PPAR)-gamma, and thus, this class of ARBs has been mostly focused on their effects on lipid metabolism. Based on the pleiotropic effects on lipid metabolism, we can envision that ARBs would provide the promising outcome for hypertensive patients aggregating metabolic risk factors, including dyslipidemia.
