Diacetylnalorphine (BAN), also known as O3,O6-diacetyl-N-allyl-normorphine, is an opioid drug described as an analgesic and antidote which was never marketed.{{cite book| vauthors = Ganellin CR, Triggle DJ |title=Dictionary of Pharmacological Agents|url=https://books.google.com/books?id=A0THacd46ZsC&pg=PA1395|date=21 November 1996|publisher=CRC Press|isbn=978-0-412-46630-4|pages=1395–}} It is the 3,6-diacetyl ester of nalorphine, and therefore the heroin analogue of nalorphine. Diacetylnalorphine may behave as a prodrug to nalorphine, similarly to the cases of heroin (diacetylmorphine) to morphine and diacetyldihydromorphine to dihydromorphine.
