Thebaine (paramorphine) is an opiate alkaloid. A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but produces stimulatory, with strychnine-like convulsions, rather than depressant effects. Thebaine is not used therapeutically, but is converted industrially into a variety of compounds including oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine and etorphine.
