Aliskiren in the Treatment of Hypertension and Organ Damage
Cardiovascular Therapeutics, 11/30/2010
Riccioni G – Hypertension is one of the most important risk factor and cause of cardiovascular diseases (CVD). Chronic activation of the renin–angiotensin–aldosterone system (RAAS) plays a key role in the development of hypertension, cardiac and renal diseases. RAAS inhibitors, such as angiotensin–converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARBs), improve cardiovascular and renal outcomes. However, studies have shown that residual morbidity and mortality remains high, despite current optimal treatment. More comprehensive control of the RAAS might provide additional reductions in morbidity and mortality. Direct renin inhibitors such aliskiren offer the potential for enhanced RAAS control as they target the system at the point of activation, thereby reducing plasma renin activity; by contrast, ACEI and ARBs increase plasma renin activity. The efficacy of aliskiren in the reduction of major clinical events is being tested in large ongoing clinical trials.
