Angiotensin receptor blocker/diuretic combination preserves insulin responses in obese hypertensives.

ABSTRACT:

Background

Thiazide diuretics can impair glucose metabolism and increase new-onset diabetes. Adding an angiotensin receptor blocker to diuretics may protect against these metabolic effects; however, the mechanism of this protection is unclear.

Method

To explore potential mechanisms, a 16-week multicenter trial was conducted to ascertain the relative glucose metabolism effects of combined hydrochlorothiazide and angiotensin receptor blocker (valsartan) therapy compared with hydrochlorothiazide and calcium channel blocker (amlodipine) treatment in 412 centrally obese hypertensive individuals (BMI = 35 +/- 7 kg/m, seated BP = 159 +/- 8/94 +/- 8 mmHg, and mean age 56 years). Individuals were randomized to valsartan/hydrochlorothiazide, with force-titration to 320/25 mg or hydroc
