Angiotensin II-receptor antagonist in the treatment of hypertension

Effective treatment of high blood pressure levels represents a crucial point in reducing global cardiovascular risk, and several studies have clearly demonstrated a significant reduction in cardiovascular and renal morbidity and mortality with a more intensive blood pressure-lowering treatment. Other factors beyond blood-pressure control may be important in reducing the risk related to hypertension. Pharmacologic agents blocking the renin-angiotensin system, in particular the angiotensin II-receptor blocker (ARB), a novel class of antihypertensive agents, represent an important addition to the therapeutic options for hypertension management, and recent large, international, randomized, trials have demonstrated that ARBs have clinical benefits across the spectrum of disease severity. In this article, we provide some evidence derived from these trials, supporting a role for ARBs in primary and secondary prevention of cardiovascular and renal disease, beyond blood pressure control
