| Primary | Pairwise Comparison of Aliskiren/Amlodipine 150/5 mg vs. Aliskiren 150 mg on Change in Mean Sitting Diastolic Blood Pressure (msDBP) | The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. | Baseline to end of study (Week 8) | No |
