Torasemide (rINN) or torsemide (USAN) is a pyridine-sulfonylurea type loop diuretic mainly used in the management of edema associated with congestive heart failure. It is also used at low doses for the management of hypertension. It is marketed under the brand name Demadex.

Additional recommended knowledge

Compared to other loop diuretics, torasemide has a more prolonged diuretic effect than equipotent doses of furosemide and relatively decreased potassium-loss. There is no evidence of torasemide-induced ototoxicity demonstrated in humans (Dunn et al., 1995).
