Furethidine
Furethidine
Chemical compound
Furethidine[2][3][4] is a 4-phenylpiperidine 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]
