A Study to Evaluate the Combination of Valsartan and Amlodipine in Hypertensive Patients Not Controlled on Monotherapy

A Double-blind, Randomized, Multicenter Study to Evaluate the Effectiveness of the Combination of Valsartan & Amlodipine in Hypertensive Patients Not Controlled on Monotherapy

This study is designed to provide additional efficacy and safety data for a treatment strategy based on the combination valsartan with amlodipine in hypertensive patients previously treated with monotherapy and remaining uncontrolled. A naturalistic approach will be taken comparing two different doses, i.e. 160mg of valsartan with amlodipine 5mg and 10mg with possible addition of HCTZ

• Patients treated with monotherapy at a dose considered as adequate by the investigator for a minimum of two months prior to Visit 1

Exclusion criteria

• Known or suspected contraindications, including history of allergy to ARBs, CCB, thiazides or to drugs with similar chemical structure.
