API Description: Originally developed in the 1950s as a malaria treatment, hydralazine showed antihypertensive ability and was soon repurposed. Hydralazine is a hydrazine derivative vasodilator used alone or as adjunct therapy in the treatment of hypertension and only as adjunct therapy in the treatment of heart failure. Hydralazine is no longer a first line therapy for these indications since the development of newer antihypertensive medications. Hydralazine hydrochloride was FDA approved on 15 January 1953.
