Opioid. Schedule ii controlled medication. Opioid (semi-synthetic) used for analgesia in patients.
A strong narcotic. It is a drug that you should take for sever pain (and possibly moderate pain) and only for a short period of time if you don't have a chronic debilitating illness in which narcotics are helpful for keeping the pain in check. Basically narcotics do not prevent the pain. They just make you not care about it. Anesthetics such as local or general prevent transmission of pain.
It's an opiate. Oxycodone is a semi-synthetic opiate derived from codeine. It is far more potent (5 mg of oxycodone = 30-60 mg of codeine) because it is better absorbed and isn't extensively metabolized in the liver. It also has far fewer side effects, especially histamine release, than does Codeine or morphine, and it hits the brain very fast. It therefore has very high abuse potential, similar to heroin.
