Purpose

Methadone is a first-line, evidence-based treatment for opioid use disorder (OUD). Unfortunately, retention and adherence in methadone treatment is a major challenge. OUD patients frequently present with co-morbid depression (OUDCD), a risk factor for poor OUD treatment outcomes, overdose, and suicide. The last two decades have seen an exciting and transformational development in the treatment of depression - ketamine. As a safe, rapid-acting anti-depressant deliverable within the context of methadone maintenance treatment, ketamine could feasibly change the landscape of treatment for OUD patients with comorbid depression. This proposal seeks to evaluate implementation outcomes (feasibility and patient acceptance) as well as preliminary efficacy of ketamine on methadone treatment outcomes for OUD patients (n=6) with comorbid depression and depressive symptoms presenting for methadone treatment.

Ketamine
  • Drug: Ketamine Hydrochloride
    Ketamine will be administered by a nurse in a 2-week treatment phase, during which participants will receive six IV infusions of 0.5 mg/kg (over 40-50 minutes) ketamine three times per week. Infusion days for patients will be on Mondays, Wednesdays, and Fridays, +/- 1 day. Ketamine infusions will take place at the UMB General Clinical Research Center (GCRC). The GCRC nurse will deliver ketamine within a private exam room. The infusions will last 40-50 min, and the participant will be observed by the GCRC clinical staff for 2 hours post-infusion. Vital signs will be monitored throughout the treatment; specifically, blood pressure, pulse ox and heart rate will be checked prior to treatment, q20 minutes during infusion, and q30-60 minutes after infusion for up to three hours.
