  4. Buprenex Stadol Vicodin Demerol Morphine sulfate Fentanyl Nubain Trexan Narcan We’ll talk about

  5. Buprenexbuprenorphine • Class • Opioid analgesic (agonist – antagonist) • Schedule V • Indications • Management of moderate to severe pain

  6. Action • Binds to opiate receptors in CNS (30x morphine and 3x narcan) • Alters perception of and response to pain • Produces generalized CNS depression

  7. Contraindications • Hypersensitivity • Precautions • Increased ICP • Adverse reactions, SE • Nausea/Vomiting • Dizzyness • Headache • Confusion • Dysphoria • Sedation • Sweating

  8. Route & dosage • IV, 0.3 mg q 4-6 h prn • How supplied • 0.3 mg/ml in 1 ml preload

  9. Stadolbutorphanol tartrate • Class • Opioid analgesic (agonist/antagonist) • Indications • Management of moderate to severe pain • Analgesic during labor

  10. Action • Binds to opiate receptors in CNS • Alters perception of response to painful stimuli • Contraindications • Hypersensitivity • Opioid dependency

  11. Precautions • Head trauma • Increased ICP • Adverse reactions, SE • Confusion • Dysphoria • Hallucinations • Sedation • Sweating • Use with extreme precautions in patient on MAO Inhibitors
