A diuretic (/ ˌ d aɪ j ʊ ˈ r ɛ t ɪ k /) is any substance that promotes diuresis, the increased production of urine. This includes forced diuresis. A diuretic tablet is sometimes colloquially called a water tablet. There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys ...
Thiazide diuretics inhibit this receptor, causing the body to release NaCl and water into the lumen, thereby increasing the amount of urine produced each day. [6] An example of a molecule that is chemically a thiazide but not used as a diuretic is methylchloroisothiazolinone , often found as an antimicrobial in cosmetics.
A thiazide-like diuretic is a sulfonamide diuretic that has similar physiological properties to a thiazide diuretic, but does not have the chemical properties of a thiazide, lacking the benzothiadiazine molecular structure. Examples include metolazone, chlorthalidone, and indapamide. [1]
An osmotic diuretic is a type of diuretic that inhibits reabsorption of water and sodium (Na). They are pharmacologically inert substances that are given intravenously. They increase the osmolarity of blood and renal filtrate. [1] This fluid eventually becomes urine. Two examples are mannitol [2] and isosorbide.
Potassium-sparing diuretics or antikaliuretics [1] refer to drugs that cause diuresis without causing potassium loss in the urine. [2] They are typically used as an adjunct in management of hypertension , cirrhosis , and congestive heart failure . [ 3 ]
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. Most often taken in pill form, it is usually taken orally once or twice a day.
Loop diuretics are 90% bonded to proteins and are secreted into the proximal convoluted tubule through organic anion transporter 1 (OAT-1), OAT-2, and ABCC4.Loop diuretics act on the Na +-K +-2Cl − symporter (NKCC2) in the thick ascending limb of the loop of Henle to inhibit sodium, chloride and potassium reabsorption.
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.
