To review the safety, efficacy, pharmacology, pharmacokinetics, and drug interactions of aliskiren for the treatment of mild-to-moderate hypertension. A literature search was conducted using MEDLINE (1966-January 2007), International Pharmaceutical Abstracts (1970-January 2007), and Cochrane database (2006) for the key words aliskiren or SPP100. References of selected articles were also reviewed. Abstract data were included only in the absence of significant published data. Available English-language data from reviews, abstracts, and clinical trials were selected. For review of efficacy, randomized controlled trials were preferred. Aliskiren is a renin inhibitor, the first in a new class of antihypertensives. As renin catalyzes the rate-limiting step of the renin-angiotensin system (RAS), renin inhibition may offer a theoretical advantage over other RAS inhibitors, such as angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs). In short-term clinical trials (< or =8 wk) of subjects with mild-to-moderate hypertension, single daily doses of aliskiren 150-300 mg produced significant systolic and diastolic blood pressure reduction similar to that achieved with ACE inhibitors and ARBs, with placebo-like tolerability, without an elevation in heart rate or evidence of tolerance. Aliskiren appears to be a safe and effective treatment option in mild-to-moderate hypertension. Although long-term outcome data have not been published, aliskiren is a promising option for RAS inhibition.
