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 ...
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.
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.
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.
Osmotic diuresis is the increase of urination rate caused by the presence of certain substances in the proximal tubule (PCT) of the kidneys. [2] The excretion occurs when substances such as glucose enter the kidney tubules and cannot be reabsorbed (due to a pathological state or the normal nature of the substance).
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]
The thiazide diuretics also deplete circulating potassium unless combined with a potassium-sparing diuretic or supplemental potassium. Some authors have challenged thiazides as first line treatment. [55] [56] [57] However, as the Merck Manual of Geriatrics notes, "thiazide-type diuretics are especially safe and effective in the elderly." [58]
