Dette resulterer i en yderligere placebo - korrigeret blodtryksreduktion på 7- 10/ 3- 6 mmHg (systolisk/ diastolisk) i gennemsnit.
In patients not adequately controlled by irbesartan alone, the addition of a low dose of hydrochlorothiazide (12.5 mg) to irbesartan once daily results in a further placebo-adjusted blood pressure reduction at trough of 7-10/ 3-6 mm Hg (systolic/ diastolic).
