title: Aliskiren: a review of its use as monotherapy and as combination therapy in the management of hypertension.
abstract: Aliskiren is an orally administered, nonpeptide direct renin inhibitor indicated for the management of hypertension. Aliskiren was effective in controlling blood pressure (BP) as monotherapy and in combination with other antihypertensives, in large, randomized trials. Aliskiren 150-300 mg/day as monotherapy was effective in lowering BP across short- (≤12 weeks) and longer-term (up to 54 weeks) periods, providing sustained and consistent effects with 24-hour BP control. Compared with other antihypertensives, aliskiren was generally as effective as hydrochlorothiazide (HCTZ), valsartan, losartan, irbesartan and lisinopril in reducing BP. Furthermore, short-term aliskiren was noninferior to ramipril in reducing BP, but with a longer treatment duration, a greater efficacy of aliskiren-based therapy over ramipril-based therapy was demonstrated. Additional BP-lowering effects occurred when aliskiren was coadministered (as a fixed-dose combination or separate tablets) with other antihypertensives, including HCTZ, valsartan and amlodipine, according to large, randomized trials of short- (≤12 weeks) and longer-term (up to 54 weeks) duration. Combination therapy with aliskiren plus HCTZ was effective in hypertensive patients when administered as initial therapy or to patients previously treated with HCTZ or aliskiren monotherapy. Aliskiren-based therapy was also effective in lowering BP in obese patients, patients with type 1 or 2 diabetes mellitus, patients with metabolic syndrome and the elderly. Aliskiren efficacy was observed irrespective of patient age, sex or ethnicity. Aliskiren monotherapy or combination therapy was generally well tolerated over short- and longer-term study durations in large, randomized clinical trials. Clinical trials to evaluate the effects of aliskiren on clinical outcomes, including renoprotective and cardioprotective effects, are currently ongoing. Thus, aliskiren is a useful option for the treatment of patients with stage 1 to stage 2 (mild to moderate) hypertension, alone or in combination with other antihypertensives, including HCTZ, valsartan or amlodipine.
