Loop diuretics are pharmacological agents that primarily inhibit the Na-K-Cl cotransporter located on the luminal membrane of cells along the thick ascending limb of the loop of Henle. [4] They are often used for the treatment of hypertension and edema secondary to congestive heart failure , liver cirrhosis , or chronic kidney disease .
Bartter syndrome (BS) is a rare inherited disease characterised by a defect in the thick ascending limb of the loop of Henle, which results in low potassium levels (hypokalemia), [2] increased blood pH (), and normal to low blood pressure.
The antihypertensive actions of some diuretics (thiazides and loop diuretics in particular) are independent of their diuretic effect. [ 1 ] [ 2 ] That is, the reduction in blood pressure is not due to decreased blood volume resulting from increased urine production , but occurs through other mechanisms and at lower doses than that required to ...
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 ]
Furosemide and other loop diuretics inhibit the activity of NKCC2, thereby impairing sodium reabsorption in the thick ascending limb of the loop of Henle. The action of these loop diuretics also reduces potassium reabsorption through the NKCC2 cotransporter and consequently increases tubular flow rate which enhances potassium secretion and ...
Loop and thiazide diuretics carry this side effect. The loop diuretic furosemide is associated with ototoxicity, particularly when doses exceed 240 mg per hour. [21] The related compound ethacrynic acid has a higher association with ototoxicity, and is therefore used only in patients with sulfa allergies. Diuretics are thought to alter the ...
Torasemide is a sulfonamide and loop diuretic. [1] Use is not recommended in pregnancy or breastfeeding. [2] It works by decreasing the reabsorption of sodium by the kidneys. [1] Torasemide was patented in 1974 and came into medical use in 1993. [3] It is on the World Health Organization's List of Essential Medicines. [4]
