Oxilorphan (INN, USAN) (developmental code name L-BC-2605) is an opioid antagonist of the morphinan family that was never marketed.[1] It acts as a μ-opioid receptor (MOR) antagonist but a κ-opioid receptor (KOR) partial agonist, and has similar effects to naloxone and around the same potency as an MOR antagonist.[2] Oxilorphan has some weak partial agonist actions at the MOR (with miosis, nausea, dizziness, and some euphoria observed)[3][4] and can produce hallucinogenic/dissociative effects at sufficient doses, indicative of KOR activation.[5] It was trialed for the treatment of opioid addiction, but was not developed commercially.[6] The KOR agonist effects of oxilorphan are associated with dysphoria, which combined with its hallucinogenic effects, serve to limit its clinical usefulness; indeed, many patients who experienced these side effects refused to take additional doses in clinical trials.[7]
