Phenampromide

Phenampromide is an opioid analgesic from the ampromide family of drugs, related to other drugs such as propiram and diampromide. It was invented in the 1960s[1] by American Cyanamid Co.[2] Although never given a general release, it was trialled and 50mg codeine ≈ 60mg phenampromide. Tests on the 2 isomers showed that all of the analgesic effects were caused by the (S) isomer. In the book[3] a 4-phenyl group added to the piperidine-ring produces a drug some x60 morphine.[4] The potency derives from the fact that it overlays fentanyl. Phenampromide produces similar effects to other opioids, including analgesia, sedation, dizziness and nausea.

Phenampromide is in Schedule I of the Controlled Substances Act 1970 of the United States as a Narcotic with ACSCN 9638 with a zero aggregate manufacturing quota as of 2014. The free base conversion ratio for salts includes 0.88 for the hydrochloride.[5] It is listed under the Single Convention for the Control of Narcotic Substances 1961 and is controlled in most countries in the same fashion as is morphine.
