Description
Inclusion Criteria:
- Male and female outpatients 65 years of age and older.
- Patients who are eligible and able to participate in the study, and who consent to do so after the purpose and nature of the investigation has been clearly explained to them (written informed consent).
- At the randomization visit patients must have an office msSBP greater than or equal to 150 mmHg and < 180 mmHg (msDBP <110 mmHg) with a less than or equal to 15 mmHg difference during the last two visits of the single blind run-in period.
Exclusion Criteria:
- Severe hypertension [Office msDBP ≥110 mmHg and/or mean sitting systolic blood pressure (msSBP) ≥ 180 mmHg].
- History or evidence of a secondary form of hypertension.
- Known Keith-Wagener grade III or IV hypertensive retinopathy.
- History of hypertensive encephalopathy or cerebrovascular accident, including a history of transient ischemic cerebral attack (TIA).
- Current diagnosis of heart failure (NYHA Class II-IV).
- History of myocardial infarction, coronary bypass surgery, or any percutaneous coronary intervention (PCI).
- Current angina pectoris requiring pharmacological therapy other than nitrates.
Other protocol-defined inclusion/exclusion criteria applied to the study.

|
Percentage of Patients Achieving Systolic Blood Pressure Response
Time Frame: Baseline to end of study (Week 8)
|
Patients achieving a systolic blood pressure response had to have a msSBP < 140 mmHg at the end of the study and/or a ≥ 20 mmHg reduction in msSBP from baseline to the end of the study.
|
Baseline to end of study (Week 8)
|
Change in Mean 24 Hour Ambulatory Systolic and Diastolic Blood Pressure From Baseline to End of Study
Time Frame: Baseline to end of study (Week 8)
|
Two 24-hour ambulatory blood pressure monitoring (ABPM) evaluations were performed, one at baseline and one at the end of the study.
For each evaluation, the ABPM device was attached to the non-dominant arm of the patient.
|
Baseline to end of study (Week 8)
|
Change in the Smoothness Index (SI) of the Ambulatory Systolic Blood Pressure From Baseline to End of Study (Week 8)
Time Frame: Baseline to end of study (Week 8)
|
Smoothness index (SI) is a measure of consistency of the BP reduction over 24 hours.
The SI was obtained by first calculating the mean blood pressure value at each hour of the 24-hour ambulatory blood pressure monitoring period, both before and during treatment.
Similarly, the change from baseline in blood pressure was calculated at each hour.
The average hourly change from baseline (δh) and standard deviation (std δh) of the hourly changes were computed, and the SI was derived: SI = δh/std δh.
A negative change score indicates improvement.
|
Baseline to end of study (Week 8)
|
Change in Morning Surge of Ambulatory Systolic Blood Pressure From Baseline to End of Study (Week 8)
Time Frame: Baseline to end of study (week 8)
|
The morning surge was defined as the average of the hourly means in the last three hours (hours 22, 23, 24) of the 24 hour ambulatory blood pressure monitoring assessment period.
|
Baseline to end of study (week 8)
