A Study of VAH631 in Patients With Essential Hypertension (Factorial Study)

The purpose of this study is to compare the effect of the fixed combination of valsartan+hydrochlorothiazide (HCTZ) on blood pressure reduction with valsartan and HCTZ alone and whether the combination treatments are safe and well tolerated. The study aims to establish a dose response relationship for both monotherapies and the combinations. This study is being conducted in Japan...
