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 ...
Triamterene directly blocks the epithelial sodium channel [4] (ENaC) on the lumen side of the kidney collecting tubule. [5]: 127 Other diuretics cause a decrease in the sodium concentration of the forming urine due to the entry of sodium into the cell via the ENaC, and the concomitant exit of potassium from the principal cell into the forming urine.
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 sulfonylureas and thiazide diuretics are newer drug groups based upon the antibacterial sulfonamides. [1] [2] Allergies to sulfonamides are common. The overall incidence of adverse drug reactions to sulfa antibiotics is approximately 3%, close to penicillin; [3] hence medications containing sulfonamides are prescribed carefully.
Mercurial diuretics cause diuresis by reducing the reabsorption of sodium in the ascending loop of Henle, thus causing more water being delivered to the distal convoluted tubule. Unfortunately, earlier physicians misconstrued hallmark symptoms of mercury poisoning such as excessive salivation as signs of mercury's efficacy until the early 1960s ...
Chlortalidone, also known as chlorthalidone, is a thiazide-like diuretic drug [1] used to treat high blood pressure, swelling (such as occurs in heart failure, liver failure, and nephrotic syndrome), diabetes insipidus, and renal tubular acidosis.
Torasemide, also known as torsemide, is a diuretic medication used to treat fluid overload due to heart failure, kidney disease, and liver disease. It is a less preferred treatment for high blood pressure. [1] It is taken by mouth or by injection into a vein. [1]
Metolazone and a loop diuretic will synergistically enhance diuresis over the use of either agent alone. Using this combination, diuretic effects will occur at two different segments of the nephron; namely, the loop diuretic will act at the loop of Henle, and metolazone will act at the distal convoluted tubule. Metolazone is frequently ...
