Abstract

This randomized, double-blind, placebo-controlled study assessed the efficacy, safety, and tolerability of aliskiren 75, 150, and 300 mg to clarify the dose-response relationship and characterize the optimum aliskiren dose when given with a light meal to elderly hypertensive patients. After washout, 754 patients aged ≥65 years with hypertension (mean sitting systolic blood pressure [msSBP] ≥150 and <180 mm Hg; mean sitting diastolic blood pressure [msDBP] <110 mm Hg) were randomized to aliskiren 75, 150, or 300 mg or placebo for 8 weeks; medication was taken each morning with a light meal. The primary efficacy variable was change in msSBP from baseline to week 8 end point. Change from baseline in msDBP and dose-response curves for aliskiren 75, 150, and 300 mg were also assessed. At week 8 end point, all 3 aliskiren doses provided significantly greater least squares mean reductions in msSBP/msDBP (75 mg, 13/5 mm Hg; 150 mg, 15/6 mm Hg; 300 mg, 14/7 mm Hg) compared with placebo (8/4 mm Hg; P < .05). Aliskiren was generally well tolerated at all doses. There was a significant dose-response relationship for aliskiren, with an estimated minimum effective dose of 81.9 mg. In conclusion, aliskiren 150 and 300 mg provided effective blood pressure control in elderly patients when given with a light meal.
