    Area of Science:

    • Pharmacology
    • Medicinal Chemistry

    Background:

    • Xorphanol is a newly developed mixed agonist-antagonist analgesic.
    • It belongs to the morphinan class of compounds.

    Purpose of the Study:

    • To evaluate the clinical efficacy and safety of xorphanol as an oral analgesic.
    • To investigate the pharmacological profile of xorphanol, including its interaction with opioid antagonists.

    Main Methods:

    • Animal experiments were conducted to predict physical dependence liability.
    • In vitro studies assessed anti-naloxone properties and resistance to opioid antagonists.
    • Clinical trials evaluated xorphanol's efficacy and tolerability for pain relief.

    Main Results:

    • Animal studies suggest a low physical dependence liability for xorphanol in humans.
