Loop diuretics are pharmacological agents that primarily inhibit the Na-K-Cl cotransporter located on the luminal membrane of cells along the thick ascending limb of the loop of Henle. [4] They are often used for the treatment of hypertension and edema secondary to congestive heart failure , liver cirrhosis , or chronic kidney disease .
Hydrochlorothiazide, sold under the brand name Hydrodiuril among others, is a diuretic medication used to treat hypertension and swelling due to fluid build-up. [4] Other uses include treating diabetes insipidus and renal tubular acidosis and to decrease the risk of kidney stones in those with a high calcium level in the urine. [4]
The term "thiazide" is also often used for drugs with a similar action that do not have the thiazide chemical structure, such as chlorthalidone, metolazone and indapamide. These agents are more properly termed thiazide-like diuretics. [citation needed] Thiazide diuretics also increase calcium reabsorption at the distal tubule.

Gout may be worsened by thiazide diuretics, while losartan reduces serum urate. [64] Kidney stones may be improved with the use of thiazide-type diuretics [65] Heart block. β-blockers and nondihydropyridine calcium channel blockers should not be used in patients with heart block greater than first degree. JNC8 does not recommend β-blockers as ...
The thiazide-like diuretics (indapamide and chlorthalidone) reduce risk of major cardiovascular events and heart failure in hypertensive patients compared with hydrochlorothiazide with a comparable incidence of adverse events. [5] Both thiazide diuretics and thiazide-like diuretics are effective in reducing risk of stroke.
Chlortalidone is considered a first-line medication for treatment of high blood pressure. [2] Some recommend chlortalidone over hydrochlorothiazide. [1] [15] A meta-analysis of randomized controlled trials found that chlortalidone is more effective than hydrochlorothiazide for lowering blood pressure, while the two drugs have similar toxicity.
An L-type calcium channel with its subunits labeled along with some drugs known to inhibit the channel. The L-type calcium channel (also known as the dihydropyridine channel, or DHP channel) is part of the high-voltage activated family of voltage-dependent calcium channel. [2] "L" stands for long-lasting referring to the length of activation.
