Dimenoxadol (INN; also known as dimenoxadole (BAN) or dimenoxadole; brand name Estocin in Russia) is an opioid analgesic which is a benzilic acid derivative, closely related to benactyzine (an anticholinergic). Further, the structure is similar to methadone and related compounds like dextropropoxyphene.

It was invented in Germany in the 1950s,^[2] and produces similar effects to other opioids, including analgesia, sedation, dizziness and nausea.^[3]^[4]^[5]

In the United States it is a Schedule I Narcotic controlled substance with an ACSCN of 9617 and a 2013 annual aggregate manufacturing quota of zero.
