Efficacy and Safety of Valsartan/Hydrochlorothiazide Combination Therapy in Patients With Hypertension

This is a double-blind study to evaluate the reduction in systolic blood pressure using a therapy initiated with valsartan 160 mg or valsartan + hydrochlorothiazide (HCTZ) 160/12.5 mg compared to a more conventional approach (therapy initiated with low-dose valsartan 80 mg)...
