'''Meprodine''' is an opioid analgesic that is an analogue of pethidine (meperidine). It is closely related to the drug prodine, the only difference being that meprodine has an ethyl group rather than a methyl at the 3-position of the piperidine ring.<ref>{{cite book | vauthors = Morton IK, Hall JM |title=Concise Dictionary of Pharmacological Agents : Properties and Synonyms. |date=October 2012 |publisher=Springer |location=New York |isbn=978-94-010-5907-7 | page = 176 | chapter = Meprodine | chapter-url = https://books.google.com/books?id=tsjrCAAAQBAJ&dq=Meprodine&pg=PA176 }}</ref>
As with prodine, there are two isomers of meprodine, alpha-meprodine and beta-meprodine, with the alpha isomer having been more widely used. Alphameprodine (ACSCN 9604) and betameprodine (ACSCN 9608) are both Schedule I Narcotic controlled substances in the United States, both with annual aggregate manufacturing quotas of 2 grammes as of 2014.<ref>{{cite web | title = Quotas - 2014 | url = http://www.deadiversion.usdoj.gov/fed_regs/quotas/2014/fr0825.htm | work = Diversion Control Division | publisher = Drug Enforcement Administration, U.S. Department of Justice }}</ref>
Meprodine has similar effects to other opioids, and produces analgesia, sedation and euphoria. Side effects can include itching, nausea and potentially serious respiratory depression which can be life-threatening.
==Legal Status==
===Australia=== Meprodine is considered a Schedule 9 prohibited substance in Australia under the Poisons Standard (February 2017).<ref name="Poisons Standard">{{cite web | title = Poisons Standard | date = October 2015 | url = https://www.legislation.gov.au/Details/F2017L00057 | publisher = Australian Government | work = Federal Register of Legislation }}</ref> A Schedule 9 substance is a substance which may be abused or misused, the manufacture, possession, sale or use of which should be prohibited by law except when required for medical or scientific research, or for analytical, teaching or training purposes with approval of Commonwealth and/or State or Territory Health Authorities.<ref name="Poisons Standard" />
