Direct comparison of doses did not show evidence of dose dependence for blood pressure-lowering for any of the other thiazides for which RCT data were available : bendrofluazide , chlorthalidone , cyclopenthiazide , metolazone or indapamide .
This is based on an informal indirect comparison of results observed in other Cochrane review s on ACE inhibitors , ARBs and renin inhibitors compared with placebo , which used similar inclusion /exclusion criteria to the present review .Thiazides reduced potassium , increased uric acid and increased total cholesterol and triglycerides .
These effects were dose-related and were least for hydrochlorothiazide .
Chlorthalidone increased serum glucose but the evidence was unclear for other thiazides .
This systematic review shows that hydrochlorothiazide has a dose-related blood pressure-lowering effect .
Thiazides reduced potassium , increased uric acid and increased total cholesterol and triglycerides
BACKGROUND Hypertension is a modifiable cardiovascular risk factor .
Although it is established that low-dose thiazides reduce mortality as well as cardiovascular morbidity , the dose-related effect of thiazides in decreasing blood pressure has not been subject to a rigorous systematic review .
It is not known whether individual drugs within the thiazide diuretic class differ in their blood pressure-lowering effects and adverse effects .
OBJECTIVES To determine the dose-related decrease in systolic and /or diastolic blood pressure due to thiazide diuretics compared with placebo control in the treatment of patients with primary hypertension .
Secondary outcomes included the dose-related adverse events leading to patient withdrawal and adverse biochemical effects on serum potassium , uric acid , creatinine , glucose and lipids .
Compliance to treatment for hypertension in elderly patients: the SHEP pilot study. Systolic Hypertension in the Elderly Program.
Assessing the compliance of people over 60 years of age and older with an antihypertensive treatment regimen was a major objective of the Systolic Hypertension in the Elderly Program ( SHEP ) pilot study . The study r and omized 551 men and women over the age of 60 ( mean age = 72 years ) to a stepped care treatment that included chlorthalidone or placebo in a double-blind trial . Three measures of compliance to treatment protocol --pill count , self-report , and a urine chlorthalidone assay -- all indicated high levels of compliance in 80 to 90 % of participants at 3 months and 1 year after r and omization . Pill-taking compliance was similar in the active and placebo groups , although the rate of discontinuance from study medications at 1 year was higher in the placebo than in the active group . Compliance was high in all age categories , including those over age 80 . These data suggest that elderly patients can achieve high levels of compliance with antihypertensive medications
