Chlorthalidone is a thiazide-like diuretic, an inhibitor of the Na+-Cl- cotransporter.
Chlorthalidone is a thiazide-like diuretic, an inhibitor of the Na+-Cl- cotransporter. Chlorthalidone inhibits sodium ion transport across the renal tubular epithelium increasing the delivery of sodium to the distal renal tubule and indirectly increasing potassium excretion via the sodium-potassium exchange mechanism. Chlorthalidone also promotes Ca++ reabsorption by an unknown mechanism. Several recent comparison studies inidcate that chlorthalidone may be a better drug in preventing cardiovascular events than hydrochlorothiazide.

Journal of clinical hypertension (Greenwich, Conn.), 14(9), 623-629 (2012-09-06)
Indirect evidence suggests that chlorthalidone may be more effective than hydrochlorothiazide (HCTZ), but direct comparisons are lacking. Using national Veterans Administrative pharmacy data from 2003 to 2008, the authors performed a retrospective cohort study examining the effectiveness of chlorthalidone and

This study compared the efficacy and safety of fixed-dose combinations (FDCs) of the angiotensin II receptor blocker azilsartan medoxomil (AZL-M) and the thiazide-like diuretic chlorthalidone (CLD) with the individual monotherapies in a double-blind factorial study. A total of 1714 patients

Thiazide-type diuretics are the most commonly used blood pressure (BP)-lowering drug for patients with uncomplicated hypertension. However, it has remained unclear whether hydrochlorothiazide (HCTZ) or chlorthalidone (CTD) shows better improvement in central aortic pressure. We conducted an open-label, randomized, prospective

Chlorthalidone has proven efficacy to reduce cardiovascular morbidity and mortality, yet it is infrequently used in practice. This study provides a direct comparison of chlorthalidone with hydrochlorothiazide, each combined with the angiotensin receptor blocker azilsartan medoxomil, on blood pressure reduction
Feras Karadsheh et al.
Current hypertension reports, 14(5), 416-420 (2012-08-14)
Thiazide and thiazide-like diuretics have been widely used as blood pressure-lowering agents for more than 5 decades. However, their use in patients with advanced chronic kidney disease has been limited and often discouraged. The exact mechanism of how thiazide and
