What is Torasemide?

Plain description, key identifiers and synonyms

Torasemide is an N-sulfonylurea obtained by formal condensation of [(3-methylphenyl)amino]pyridine-3-sulfonic acid with the free amino group of N-isopropylurea. It is a potent loop diuretic used for the treatment of hypertension and edema in patients with congestive heart failure. It has a role as an antihypertensive agent and a loop diuretic. It is an aminopyridine, a secondary amino compound and a N-sulfonylurea. It is functionally related to a 4-aminopyridine.
