Abstract Background Opioid use disorder (OUD) is a chronic relapsing condition associated with substantial mortality. Although medications for opioid use disorder (MOUD) can be effective in reducing opioid use and improving treatment outcomes, relapse to drug use remains common, highlighting the need for adjunctive interventions that address relapse-relevant symptoms not fully targeted by MOUD...
Abstract Background Opioid abstinence induces persistent emotional disturbances and widespread neuroplastic changes, in areas of the brain including the hippocampus. Although ketamine and its metabolite ( 2R,6R )-hydroxynorketamine (HNK) show potential in reversing opioid abstinence-related deficits in rodents, the molecular mechanisms underlying their efficacy remain poorly understood. Methods...
