DrugBank ID	DB01275
Name	Hydralazine
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	1-Phthalazinylhydrazine Hydrallazine Hypophthalin Hydralazine (2H)-Phthalazinone hydrazone 1-Hydrazinophthalazine Hydralazinum Hydralazine hydrochloride Phthalazin-1-ylhydrazine Hydrazinophthalazine Hydralazin Hidralazina Idralazina 6-Hydralazine Hydrazone 1(2H)-phthalazinone (1Z)-1(2H)-Phthalazinone hydrazone
Indication	Hydralazine is indicated alone or adjunct to standard therapy to treat essential hypertension.[L8782] A combination product with isosorbide dinitrate is indicated as an adjunct therapy in the treatment of heart failure.[L8785]
