Exclusion criteria

Exclusion criteria: 1. Patients with controlled blood pressure levels (MSSBP 11 mmol/l or > 200 mg/dl at Visit 1. 15.

Design outcomes

Primary

MeasureTime frame
Main Objective: To demonstrate that 4 weeks of treatment with amlodipine 10 mg plus valsartan 160 mg in fixed dose combination provide an additional mean sitting diastolic blood pressure reduction in patients not adequately responding (i.e., MSDBP = 90 mmHg) to 4 weeks of treatment with an angiotensin receptor blocker plus amlodipine 10 mg in free combination (olmesartan 20 mg plus amlodipine 10 mg). ;Secondary Objective: To evaluate the effects of 4 weeks of treatment with amlodipine 10 mg / valsartan 160 mg in fixed dose combination in patients not adequately responding (i.e., MSDBP = 90 mmHg) to 4 weeks of treatment with an angiotensin receptor blocker plus amlodipine 10 mg in free combination (olmesartan 20 mg plus amlodipine 10 mg) on mean sitting systolic blood pressure, pulse pressure, heart rate, normalization and responder rate. To assess the safety and tolerability of amlodipine 10 mg / valsartan 160 mg. ;Primary end point(s): The aim of this multicenter open-label trial is to evaluate the reduction in trough MSDBP by a 4-week treatment with the fixed dose combination of amlodipine 10 mg and valsartan 160 mg in hypertensive patients not adequately controlled by olmesartan 20 mg in free combination with amlodipine 10 mg. The main interest is the estimation and testing of the changes in BP between Visit 4 and Visit 5.
