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 .
Double-blind comparison of indapamide with a placebo in hypertensive patients treated by practicing physicians.
The antihypertensive effect of indapamide ( 2.5 mg/day ) was compared to that obtained with a placebo in a controlled trial carried out by 11 physicians in their private practice . Thirty-one patients with uncomplicated essential hypertension were included . After a run-in period of 3 weeks without any treatment , either indapamide ( n = 16 ) or a placebo ( n = 15 ) were administered for 8 weeks in double-blind fashion . Blood pressure decreased in both groups . In patients treated with indapamide , systolic pressure was significantly lower than in those given the placebo at 3 out of the 4 follow-up visits ; diastolic pressure , however , was significantly lower only at the end of the trial . Both the active drug and the placebo were well tolerated . No significant change in body weight , plasma potassium and uric acid occurred during the study in either group of patients . It appears therefore that indapamide , at a dose which apparently has no major diuretic effect , may be useful for practitioners in managing patients with mild to moderate hypertension
