Brief summary
This study will compare the blood pressure (BP) lowering effect of the combination of aliskiren/amlodipine 300/10 mg versus amlodipine 10 mg monotherapy in patients with moderate to severe hypertension by testing the hypothesis that the combination of aliskiren/amlodipine produces a superior reduction from baseline in mean sitting systolic blood pressure (msSBP) after 8 weeks of treatment.
Interventions
Each dose was taken by mouth with water at approximately 8:00 in the morning with or without food, except on the morning of the next office/clinic visit, when the medication was taken at the site after the visit procedures were completed. In order to adequately blind the study, patients were required to take a total of two tablets and one capsule of study medication per day throughout the study.
