[citation needed] Loop diuretics usually have a ceiling effect whereby doses greater than a certain maximum amount will not increase the clinical effect of the drug. Also, there is a threshold minimum concentration of loop diuretics that needs to be achieved at the thick ascending limb to enable the onset of abrupt diuresis. [10]
Loop diuretics, such as furosemide, inhibit the body's ability to reabsorb sodium at the ascending loop in the nephron, which leads to an excretion of water in the urine, whereas water normally follows sodium back into the extracellular fluid. Other examples of high-ceiling loop diuretics include ethacrynic acid and torasemide. [citation needed]
Furosemide, sold under the brand name Lasix among others, is a loop diuretic medication used to treat edema due to heart failure, liver scarring, or kidney disease. [4] Furosemide may also be used for the treatment of high blood pressure. [4] It can be taken intravenously or orally. [4]
Etacrynic acid or ethacrynic acid , trade name Edecrin, is a loop diuretic used to treat high blood pressure and the swelling caused by diseases like congestive heart failure, liver failure, and kidney failure. A con with ethacrynic acid compared to the other loop diuretic drugs such as furosemide is that it has a significantly steep dose ...

A picture showing the sites of action of diuretics in the renal tubule. Diuretics act primarily by reducing the reabsorption of sodium at different sites of the renal tubular system and consequently promoting the elimination of sodium and water with increased urine output. [3] Loop diuretics: furosemide, bumetanide, torsemide, ethacrynic acid
Loop diuretics is a major class of diuretic drugs indicated for oedema due to heart failure, liver disease and kidney disease. It is also used for treating hypertension. [26] Common examples include furosemide, bumetanide and ethacrynic acid. Loop diuretics act on the thick ascending limb of the loop of Henle in the kidney nephrons.
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 ...
