Improving blood pressure control: increase the dose of diuretic or switch to a fixed-dose angiotensin receptor blocker/diuretic? the valsartan hydrochlorothiazide diuretic for initial control and titration to achieve optimal therapeutic effect (Val-DICTATE) trial.

ABSTRACT: To assess the strategy of increasing the dose of a diuretic compared with using an angiotensin receptor blocker in combination with a diuretic, the authors performed a multicenter, randomized, parallel group trial in hypertensive patients (baseline blood pressure [BP], 153/97 mm Hg) whose BP remained uncontrolled on initial low-dose diuretic monotherapy (hydrochlorothiazide [HCTZ] 12.5 mg Hg). Patients with stage 1 and 2 hypertension were randomized to treatment with valsartan/HCTZ (160/12.5 mg) or to doubling of the HCTZ dose (25 mg). The primary end point was the percentage of patients whose clinic BP values were <140/90 mm Hg following 4 weeks of double-blind therapy. A significantly higher proportion (P<.001) of hypertensive patients met BP control levels in the valsartan/HCTZ (160/12.
