About

Study Objectives :

To demonstrate the reduction in office Blood Pressure following a 8-week regimen of irbesartan / hydrochlorothiazide using irbesartan as a reference.
To demonstrate the reduction in office Blood Pressure after 4-week regimen of irbesartan / hydrochlorothiazide using irbesartan as a reference.
To compare the response rate (defined as office Systolic Blood Pressure/Diastolic Blood Pressure reduce more than 10mmHg from Week 0) of patients after 4-week and 8-week regimen of irbesartan / hydrochlorothiazide versus irbesartan.
To compare the proportion of patients requiring titration after 4-week regimen of irbesartan/hydrochlorothiazide versus irbesartan
To ascertain the safety and tolerability of irbesartan / hydrochlorothiazide versus irbesartan when administered once daily
