Torasemide (torsemide) is a pyridine-sulfonylurea loop diuretic. It inhibits the Na+/K+/2Cl- cotransporter in the thick ascending limb of the loop of Henle, promoting excretion of water, sodium, and chloride. It manages edema secondary to heart failure, renal disease, and hepatic cirrhosis. Its structure features a sulfonylurea framework linked to a pyridinyl and phenylamino group.
