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 .
Ticrynafen and hydrochlorothiazide in hypertension
In a double‐blind study , 28 patients having mild to moderate essential hypertension were r and omly assigned to a 6‐week regimen of ticrynafen , hydrochlorothiazide , or placebo .  Blood pressure fell after ticrynafen and hydrochlorothiazide .  Serum uric acid fell strikingly with ticrynafen whereas it rose with hydrochlorothiazide .  Serum potassium declined very little with ticrynafen ; much less than with hydrochlorothiazide . Serum creatinine and blood urea nitrogen rose slightly more with ticrynafen than with hydrochlorothiazide . There were no clinical adverse effects to either of the medications . Ticrynafen appears to be an effective antihypertensive with a substantial hypouricemic effect
