Opioid Agonists
NERVOUS SYSEM: Synthetic Narcotics
Question | Answer |
---|---|
Meperidine (Demrol) | Mu agonist used for relief of acute pain such as pain occurring after orthopedic procedures. May be combined with a tranquilizer for use as an anesthetic. Naloxone preferred agonist |
Oxymorphone (Numorphan and Opana) | Semisynthetic opioid that is a mu agonist. Used for restraint in dogs, diagnostic procedures, minor surgeries. Can be combined with tranquilizers to produce neuroleptanalgesia. Naloxone is antagonist |
Butorphanol tartrate (Torbutrol, Torbugesic) | Synthetic opioid agonists/antagonist. Agonist activity exerted on kappa and sigma receptors. Antagonist activity on mu receptor. Used for analgesia and antitussive effects. |
Fentanyl | Opioid agonist used to control chronic pain |
Hydrocodone bitartrate (Hycodan, Tussigon) | Opioid agonist used as an antitussive agent in dogs |
Etorphine (M-99) | Produces analgesic effects. Lethal if injected and can be absorbed through the skin. Restricted for zoo and exotic animals. Can be reversed by antagonist dipronorphine |
Pentazocine (Talwin) | Partial opioid agonist for pain relief in horses and dogs |
Diphenoxylate (Lomotil) | Combined with atropine for use as an antidiarrhea agent |
Apomorhpine | Dopamine agonist with the principal effect of inducing vomiting by stimulating the chemoreceptor trigger zone in the brain. Often administered by placing a portion of a tablet in the conjunctival sac for absorption |
Methadone (Dolophine) | Primary use is the treatment of colic pain in horses |
Codeine | Use as an antitussive in dogs |
Carfentanil (Wildnill) | Used to induce wildlife anesthesia |
Buprenorphine (Buprenex) | Partial mu agonist-antagonist. Potent analgesic used in several small animals, especially the cat. Longer duration of action than butorphanol. |
Buprenorphine (simbadol) | SQ injection 1x/day for 3 days in cats. Provides 24hr continuous pain control after postoperative pain with surgical procedures |
Adverse Side Effects | Respiratory depression, excitement (Cats and horses), nausea, vomiting, diarrhea, defecation, panting, convulsions |
