Chlorothiazide, sold under the brand name Diuril among others, is an organic compound used as a diuretic and as an antihypertensive. [ 1 ] [ 2 ] It is used both within the hospital setting or for personal use to manage excess fluid associated with congestive heart failure .
Illustration of the mechanism of action of thiazide diuretics in the distal convoluted tubule of nephrons. Thiazide diuretics control hypertension in part by inhibiting reabsorption of sodium (Na +) and chloride (Cl −) ions from the distal convoluted tubules in the kidneys by blocking the thiazide-sensitive Na +-Cl − symporter.

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]
Mechanism of action. Normally, sodium is reabsorbed in the collecting tubules of a renal nephron. This occurs via epithelial sodium channels or ENaCs, located on the ...
At the same time, loop diuretics inhibit the tubuloglomerular feedback mechanism so that increase in salts at the lumen near macula densa does not trigger a response that reduces the GFR. [6] Loop diuretics also inhibit magnesium and calcium reabsorption in the thick ascending limb. Absorption of magnesium and calcium are dependent upon the ...
The doctors and nurses didn’t believe Tomisa Starr was having trouble breathing. Two years ago, Starr, 61, of Sacramento, California, was in the hospital for a spike in her blood pressure.
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.
Acetazolamide is an inhibitor of carbonic anhydrase.It is used for glaucoma, epilepsy (rarely), idiopathic intracranial hypertension, and altitude sickness. For the reduction of intraocular pressure (IOP), acetazolamide inactivates carbonic anhydrase and interferes with the sodium pump, which decreases aqueous humor formation and thus lowers IOP.
