Oxycodone is a semi-synthetic opioid synthesized from poppy-derived thebaine. It is a narcotic analgesic generally indicated for relief of moderate to severe pain. It was developed in 1916 in Germany[5][6] as one of several new semi-synthetic opioids in an attempt to improve on the existing opioids.[1]

Oxycodone is available as single-ingredient medication in immediate release and controlled release. Combination products formulated with non-narcotic ingredients such as NSAIDs and paracetamol (acetaminophen) are also available as immediate release formulations.
