Morpheridine

Morpheridine is a 4-phenylpiperidine derivative that is related to the opioid analgesic drug pethidine (meperidine).

Morpheridine is not currently used in medicine and is a Class A/Schedule I drug which is controlled under UN drug conventions. Presumably it has similar effects to other opioid derivatives, such as analgesia, sedation, nausea and respiratory depression.
