Novel drugs targeting hypertension: Renin inhibitors

The first renin inhibitor, aliskiren, will soon enter the clinical arena. This review summarizes the potential differences between renin inhibitors and the currently existing blockers of the renin-angiotensin system (RAS) [ie, the ACE inhibitors and the angiotensin II type 1 (AT1) receptor antagonists], taking also into consideration the recently discovered (pro)renin receptor. This receptor not only activates the inactive precursor of renin, prorenin, but it also exerts direct renin/prorenin-induced effects, independently of angiotensin. The review ends with a brief overview of the available (pre)clinical aliskiren data and a description of its safety profile.
