Chlorthalidone (Chlorthalidone) - Summary

 
 



CHLORTHALIDONE SUMMARY

Chlorthalidone is an oral antihypertensive/diuretic.

Diuretics such as chlorthalidone are indicated in the management of hypertension either as the sole therapeutic agent or to enhance the effect of other antihypertensive drugs in the more severe forms of hypertension.

Chlorthalidone is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy.

Chlorthalidone has also been found useful in edema due to various forms of renal dysfunction, such as nephrotic syndrome, acute glomerulonephritis, and chronic renal failure.

NEWS HIGHLIGHTS

Published Studies Related to Chlorthalidone

Spironolactone and chlorthalidone in uncontrolled elderly hypertensive patients treated with calcium antagonists and angiotensin II receptor-blocker: effects on endothelial function, inflammation, and oxidative stress. [2009.10]
The side effects of thiazide-type diuretics include metabolic abnormality and increased oxidative stress, which might cause endothelial dysfunction despite blood pressure reduction. In hypertensive patients with heart failure, treatment with an aldosterone antagonist resulted in improvements in endothelial function and significant blood pressure reduction...

Antihypertensive efficacy of metoprolol XL/low dose chlorthalidone (6.25 mg) combination: a randomized, comparative study in indian patients with mild-to-moderate essential hypertension. [2009.07.22]
OBJECTIVE: High blood pressure is one of the most important risk factors, directly responsible for increasing the cardiovascular morbidity and mortality. The primary objective was to evaluate the efficacy of metoprolol XL/chlorthalidone against metoprolol XL/hydrochlorothiazide with respect to mean fall in systolic and diastolic blood pressure. The secondary objective was to compare the response rates and to evaluate the tolerability of study medications in patients with mild-to-moderate essential hypertension... CONCLUSION: Chlorthalidone in combination with metoprolol XL is as effective and well tolerated as widely used combination of metoprolol XL/HCTZ, thus providing an alternative therapeutic option.

A randomized, comparative study evaluating the efficacy and tolerability of losartan-low dose chlorthalidone (6.25 mg) combination with losartan-hydrochlorothiazide (12.5 mg) combination in Indian patients with mild-to-moderate essential hypertension. [2009.07]
OBJECTIVE: The relationship of blood pressure (BP) to cardiovascular risk is linear, positive, and continuous. Lowering elevated BP reduces the risk of cardiovascular events. The primary objective of this randomized, multicenter, comparative, 3-month, open-label study was to evaluate the antihypertensive efficacy of losartan/chlorthalidone versus losartan/hydrochlorothiazide in mild-to-moderate essential hypertension... CONCLUSIONS: The losartan/low-dose chlorthalidone (6.25 mg) combination is as effective as the widely used losartan/hydrochlorothiazide combination in lowering BP and is well tolerated, thus providing a useful therapeutic option for treating mild-to-moderate hypertension.

Differential effects of chlorthalidone versus spironolactone on muscle sympathetic nerve activity in hypertensive patients. [2009.04]
CONTEXT: Previous studies in rats indicated that thiazide-type diuretics reduced blood pressure (BP) and triggered baroreflex-mediated increase in sympathetic nerve activity (SNA), whereas spironolactone exerted central sympathoinhibitory action in addition to diuretic effects. OBJECTIVES: The objectives were to determine effects of spironolactone and chlorthalidone on SNA and the role of SNA on diuretic-induced insulin resistance in human hypertension... CONCLUSIONS: Our data suggest that chlorthalidone, the first-line drug therapy for hypertension, causes persistent activation of sympathetic nervous system and insulin resistance in hypertensive patients. These side effects, however, are avoided by spironolactone despite similar reduction in BP.

Cost-effectiveness of chlorthalidone, amlodipine, and lisinopril as first-step treatment for patients with hypertension: an analysis of the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). [2008.05]
OBJECTIVE: To evaluate the cost-effectiveness of first-line treatments for hypertension. BACKGROUND: The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) found that first-line treatment with lisinopril or amlodipine was not significantly superior to chlorthalidone in terms of the primary endpoint, so differences in costs may be critical for optimizing decision-making... CONCLUSIONS: Initial treatment with chlorthalidone is less expensive than lisinopril or amlodipine, but amlodipine provided a nonsignificantly greater survival benefit and may be a cost-effective alternative. A randomized trial with power to exclude "clinically important" differences in survival will often have inadequate power to determine the most cost-effective treatment.
