Aliskiren, the first in a new class of direct renin inhibitors for hypertension: present and future perspectives

Abstract

Aliskiren, the direct renin inhibitor, is the first new class of drug available in 13 years for the treatment of hypertension. Renin has long been recognized as a preferred site for blockade of the renin-angiotensin-aldosterone system because it prevents conversion of angiotensinogen to angiotensin I. Aliskiren binds to the active site of the renin molecule, blocking angiotensinogen cleavage, thus, preventing the formation of angiotensin I. Clinical studies have demonstrated at least equivalent or superior blood pressure lowering efficacy compared with existing drugs with a favorable side effect profile. Aliskiren possesses possible synergistic potential when combined with a thiazide diuretic, ACE inhibitor, angiotensin receptor blocker and calcium channel blocker both in terms of efficacy and tolerability. This review aims to define the role of aliskiren in the therapeutic management of hypertension.
