The Effects of Moderate vs. Aggressive Treatment With Valsartan + Amlodipine on Patients With Hypertension Uncontrolled by Angiotensin-Receptor Blocker (Herein, ARB) Monotherapy

A Multicenter, Randomized, Double Blind, Parallel Design Trial to Evaluate the Blood Pressure Lowering Efficacy Comparing Moderate Versus Aggressive Treatment Regimen of Valsartan + Amlodipine in Patients Uncontrolled on ARB Monotherapy

The purpose of this trial is to compare blood pressure lowering efficacy of moderate Valsartan + Amlodipine treatment regimen (160 / 5 mg) with that of aggressive regimen (320 / 10 mg) in patients uncontrolled on ARB monotherapy, other than Valsartan

Inclusion Criteria:

• Male and female outpatients
• 18 Years of age or older
• Mean Sitting Systolic Blood Pressure (the top number) greater than or equal to 150 mmHg and lower than 200 mmHg while on Angiotensin-Receptor Blocker monotherapy for a minimum period of 28 days prior to randomization

Exclusion Criteria:

• Mean Sitting Systolic Blood Pressure (the top number) greater than or equal to 200 mmHg and/or Mean Sitting Diastolic Blood Pressure greater than or equal to 120 mmHg
• Transient ischemic attack (mini-stroke), myocardial infarction (heart attack), all types of revascularization procedures in the last 6 months
• Treatment with valsartan or any combination antihypertensive treatment with 28 days prior to screening (Visit 1)
