Benzomorphans - Morphine derivatives of the methanobenzazocine family that act as potent analgesics. |
|
Buprenorphine - A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use. |
|
Butorphanol - A synthetic morphinan analgesic with narcotic antagonist action. It is used in the management of severe pain. |
|
Dextrorphan - Dextro form of levorphanol. It acts as a noncompetitive NMDA receptor antagonist, among other effects, and has been proposed as a neuroprotective agent. It is also a metabolite of DEXTROMETHORPHAN. |
|
Diprenorphine - A narcotic antagonist similar in action to NALOXONE. It is used to remobilize animals after ETORPHINE neuroleptanalgesia and is considered a specific antagonist to etorphine. |
|
Etorphine - A narcotic analgesic morphinan used as a sedative in veterinary practice. |
|
Levallorphan - An opioid antagonist with properties similar to those of NALOXONE; in addition it also possesses some agonist properties. It should be used cautiously; levallorphan reverses severe opioid-induced respiratory depression but may exacerbate respiratory depression such as that induced by alcohol or other non-opioid central depressants. (From Martindale, The Extra Pharmacopoeia, 30th ed, p683) |
|
Levorphanol - A narcotic analgesic that may be habit-forming. It is nearly as effective orally as by injection. |
|
Morphine - The principal alkaloid in opium and the prototype opiate analgesic and narcotic. Morphine has widespread effects in the central nervous system and on smooth muscle. |
|
Nalbuphine - A narcotic used as a pain medication. It appears to be an agonist at kappa opioid receptors and an antagonist or partial agonist at mu opioid receptors. |
|
Nalorphine - A narcotic antagonist with some agonist properties. It is an antagonist at mu opioid receptors and an agonist at kappa opioid receptors. Given alone it produces a broad spectrum of unpleasant effects and it is considered to be clinically obsolete. |
|
Naloxone - A specific opiate antagonist that has no agonist activity. It is a competitive antagonist at mu, delta, and kappa opioid receptors. |
