1)A common slang term used to define oxycontin, a prescription sustained-release opioid-analgesic marketed by Purdue Pharma. It is comprised of the active ingredient oxycodone, and an inert filler. Available dosages range from 10-80mg. 160mg pills used to be available but were pulled from the market. It does not contain acetaminophen as Percocet, Endocet do. This makes it particularly desirable to those who wish to use it for 'off-label' purposes.
