Bezitramide is an opioid analgesic. Bezitramide itself is a prodrug which is readily hydrolyzed in the gastrointestinal tract to its main metabolite, despropionyl-bezitramide. Bezitramide was discovered at Janssen Pharmaceutica in 1961.[1][2][3] It is most commonly marketed under the trade name Burgodin.

The drug was pulled from the shelves in the Netherlands in 2004 after fatal overdose cases, including one where a five-year-old child took one tablet from his mother's purse, ate it, and promptly died.[4]

Bezitramide is regulated much the same as morphine in all known jurisdictions and is a Schedule II substance under the United States' Controlled Substances Act of 1970, with an ACSCN of 9800 and zero annual manufacturing quota.[5] However, it has to this point never been marketed in the United States.
