Iproclozide (trade names Sursum, Sinderesin) is an irreversible and selective monoamine oxidase inhibitor (MAOI) of the hydrazine chemical class that was used as an antidepressant, but has since been discontinued.[2] It has been known to cause fulminant hepatitis and there have been at least three reported fatalities due to administration of the drug.[3][4]
