Xorphanol (also known as TR5379M) is a full κ-opioid receptor agonist and is a partial agonist at μ opioid receptor. Clinically, xorphanol was studied as an orally active analgesic that provided effective pain relief but showed low physical dependence liability. Further development of this drug was discontinued.
