Keterangan :
Oxycodone is an opioid analgesic medication synthesized from thebaine. It was developed in 1916 in Germany, as one of several new semi-synthetic opioids with several benefits over the older traditional opiates and opioids; morphine, diacetylmorphine( heroin) and codeine. It was introduced to the pharmaceutical market as Eukodal or 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 oxycodone.
