The antihypertensive efficacy of HCTZ in its daily dose of 12.5 to 25 mg as measured in head-to-head studies by ambulatory BP measurement is consistently inferior to that of all other drug classes .
Because outcome data at this dose are lacking , HCTZ is an inappropriate first-line drug for the treatment of hypertension
OBJECTIVES The purpose of this study was to evaluate the antihypertensive efficacy of hydrochlorothiazide ( HCTZ ) by ambulatory blood pressure ( BP ) monitoring .
BACKGROUND HCTZ is the most commonly prescribed antihypertensive drug worldwide .
More than 97 % of all HCTZ prescriptions are for 12.5 to 25 mg per day .
The antihypertensive efficacy of HCTZ by ambulatory BP monitoring is less well defined .
Comparison of effects of exercise and diuretic on left ventricular geometry, mass, and insulin resistance in older hypertensive adults.
To compare the effects of exercise training and hydrochlorothiazide on left ventricular ( LV ) geometry and mass , blood pressure ( BP ) , and hyperinsulinemia in older hypertensive adults , we studied 28 patients r and omized either to a group ( age 66.4 + /- 1.3 yr ; n = 16 ) that exercised or to a group ( age 65.3 + /- 1.2 yr ; n = 12 ) that received hydrochlorothiazide for 6 mo .  Endurance exercise training induced a 15 % increase in peak aerobic power . The reduction in systolic BP was twofold greater with thiazide than with exercise ( 26.6 + /- 12.2 vs. 11.5 + /- 10.9 mmHg ) . Exercise and thiazide reduced LV wall thickness , LV mass index ( 14 % in each group ) , and the LV wall thickness-to-radius ratio ( h/r ) similarly ( exercise : before 0.48 + /- 0.2 , after 0.42 + /- 0.01 ; thiazide : before 0.47 + /- 0.04 , after 0.40 + /- 0.04 ; P = 0.017 ) . The reductions in systolic BP and h/r were correlated in the exercise group ( r = 0.70 , P = 0.005 ) but not in the thiazide group . Exercise training reduced glucose-stimulated hyperinsulinemia ( before : 13.65 + /- 2.6 vs. 9.84 + /- 1.5 mU.ml(-1).min ; P = 0.04 ) and insulin resistance . Thiazide did not affect plasma insulin levels . The results suggest that although exercise is less effective in reducing systolic BP than thiazide , it can induce regression of LV hypertrophy similar in magnitude to thiazide . Unlike hydrochlorothiazide , exercise training can improve insulin resistance and aerobic capacity in older hypertensive people
