Furethidine^[2]^[3]^[4] is a 4-phenyl piperidine derivative that is related to the clinically used opioid analgesic drug pethidine (meperidine),^[5] but with around 25x higher potency.^[6] According to another source, Furethidine is 500/30 = 16.7 x the potency of pethidine (table VII).^[7]^[8]

Furethidine is not currently used in medicine and is a Class A/Schedule I drug which is controlled under UN drug conventions. It has similar effects to other opioid derivatives, such as analgesia, sedation, nausea and respiratory depression.^[9] In the United States it is a Schedule I Narcotic controlled substance with the ACSCN of 9626.^[10]
