Oxilorphan is a non-selective opioid which is a μ antagonist but a κ partial agonist. It has similar effects to naloxone, and around the same potency as an antagonist.^[1]

Oxilorphan has some weak partial agonist effects^[2] and can produce hallucinogenic effects at high doses, suggesting some kappa opioid agonist action.^[3] It was trialled for the treatment of opiate addiction, but was not developed commercially.^[4]
