WebPharmacology and mechanism of action. Furosemide is a loop diuretic that inhibits the Na+ /K + /2Cl - cotransporter in the ascending thick loop of Henle. It is often called a high-ceiling diuretic because it is more effective than other diuretics. Furosemide decreases the sodium, chloride, and potassium reabsorption from the tubule.
