Etoxeridine (Carbetidine, Atenos) is a 4-phenyl piperidine derivative that is related to the clinically used opioid analgesic drug pethidine (meperidine).

Etoxeridine was developed in the 1950s^[2] and investigated for use in surgical anesthesia, however it was never commercialized and is not currently used in medicine.^[3]^[4]^[5] As with other opioids which were not in clinical use during the drafting of the Controlled Substances Act, it is categorized as a Schedule I narcotic.
