Oxycodone is an analgesic medication synthesized from poppy-derived thebaine. It was developed in 1916 in Germany, as one of several new semi-synthetic opioids in an attempt to improve on the existing opioids: morphine, diacetylmorphine (heroin), and codeine. Oxycodone oral medications are generally prescribed for the relief of moderate to severe pain. Currently it is formulated as single ingredient products or compounded products.
