oxycodone is also not necessarily "Oxycontin." Oxycontin is a high dose, time release buffered tablet whose active ingredient is oxycodone. Oxycodone is also the drug known in the US as Percocet if compounded with acetominophen, Percodan if compounded with aspirin.
Yeah, this is true: (Wikipedia)
Oxycodone is an opioid analgesic medication synthesized from thebaine. It was developed in 1916 in Germany and introduced to the pharmaceutical market as Eukodal® (also spelled Eucodal) and Dinarkon®. Its chemical name is derived from codeine - the chemical structures are very similar, differing only in that the hydroxyl group of codeine has been oxidized to a carbonyl group (as in ketones), hence the "-one" suffix, the 7,8-dihydro-feature (codeine has a double-bond between those two carbons), and the hydroxyl group at carbon 14 (codeine has just a hydrogen in its place), hence "oxy"codone.
In the United States, oxycodone is a Schedule II controlled substance both as a single agent and in combination with products containing paracetamol (aka acetaminophen), ibuprofen or aspirin. It was first introduced to the US market in May 1939 and is the active ingredient in a number of pain medications commonly prescribed for the relief of moderate to heavy pain, either with inert binders (Oxycodone, Oxycontin) or supplemental analgesics such as acetaminophen (Percocet, Tylox) and aspirin (Percodan).
Oxycodone is a drug subject to abuse,[1] and is included in the sections for the most strongly controlled substances that have a commonly accepted medical use under the German Betäubungsmittelgesetz III) (narcotics law), the Swiss law of the same title, UK Misuse of Drugs Act (Class A), Canadian Controlled Drugs and Substances Act (CDSA), Dutch Opium Law (List 1), Austrian Suchtmittelgesetz (Addictives Act), Australian, New Zealand, Japanese and South African controlled substance laws, to name but a few. It is also subject to international treaties controlling psychoactive drugs subject to abuse or dependence.
