Managing cardiovascular and renal risk: the potential of direct renin inhibition

Abstract

Aliskiren is the first direct renin inhibitor for the treatment of hypertension. Clinical experience from studies in over 14,000 patients has shown that aliskiren, alone or in combination with other antihypertensive therapies, provides effective blood pressure lowering with a good safety and tolerability profile.The ultimate aim of antihypertensive therapy, however, is to reduce the risk of adverse cardiovascular and renal outcomes.The effect of aliskiren on surrogate markers of organ damage and clinical outcomes is being assessed in the ongoing ASPIRE HIGHER programme, the largest clinical trials programme in the cardio-renal disease area. Results from the ALOFT, AVOID and ALLAY studies suggest that aliskiren has positive effects on markers of cardiovascular and renal damage in patients with type 2 diabetes and nephropathy, heart failure and left ventricular hypertrophy.ASPIRE HIGHER also includes four large-scale studies assessing the potential outcome benefits of aliskiren, and the results of these trials will help define the clinical utility of aliskiren in the treatment of cardiovascular and renal diseases. In this article, we review the antihypertensive efficacy of aliskiren and explore its potential in the management of cardiovascular and renal risk.
