DescriptionOriginally developed in the 1950s as a malaria treatment, hydralazine showed antihypertensive ability and was soon repurposed.[A186841] 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.[A186820,L8782,L8785] Hydralazine is no longer a first line therapy for these indications since the development of newer antihypertensive medications.[T691] Hydralazine hydrochloride was FDA approved on 15 January 1953.[L8779]
