Bezitramide

Bezitramide is an opioid analgesic. Bezitramide itself is a prodrug which is readily hydrolyzed in the gastrointestinal tract to its active metabolite, despropionyl-bezitramide.^[2] Bezitramide was discovered at Janssen Pharmaceutica in 1961.^[3][4][5] 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.^[6]

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.^[7] However, as of May 2021, it has never been marketed in the United States.
