title: Now that we have a direct renin inhibitor, what should we do with it?
abstract: Aliskiren is the first renin inhibitor to be licensed for use as an antihypertensive drug in both the United States and Europe. Opinions vary considerably concerning the future of aliskiren and renin inhibition. Some experts argue that renin inhibitors should only be prescribed when less expensive blockers of the renin-angiotensin system (RAS), with established effects on morbidity and mortality, are not tolerated or have failed to reduce blood pressure effectively. Others propose that because renin is a highly specific catalyst for the rate-limiting step of the RAS, renin inhibitors have the potential to supersede angiotensin-converting enzyme inhibitors and angiotensin receptor blockers as the preferred inhibitors of the cascade in patients with particular pathologies and/or genotypes. It has also been suggested that dual blockade of the RAS might be particularly advantageous. This review discusses the currently available evidence, and concludes with speculation concerning the future of direct renin inhibition.
