Description	Originally 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]
Synonyms	Hydralazine hydrochloride Hydrazinophthalazine (1Z)-1(2H)-Phthalazinone hydrazone Hydralazin Hydrazone 1(2H)-phthalazinone Phthalazin-1-ylhydrazine (2H)-Phthalazinone hydrazone Idralazina Hydrallazine Hidralazina 6-Hydralazine Hypophthalin 1-Phthalazinylhydrazine 1-Hydrazinophthalazine Hydralazinum Hydralazine
