Glutamatergic Modulation to Facilitate Naltrexone Initiation in Opioid Dependence
Brief Summary
Opioid dependence is a substantial problem associated with significant morbidity and mortality. Extended-release naltrexone has been found effective at reducing opioid use and maintaining abstinence, but its use has been limited by the difficulties encountered with treatment initiation, which involves detoxification from opioids and oral naltrexone titration. Improving the likelihood of a successful transition to naltrexone is therefore an important public health goal.
N-methyl-D-aspartate receptor (NMDA) antagonism has been found to alleviate the signs and symptoms of withdrawal from opioids, as well as to address adaptations associated with chronic opioid use, such as opioid-induced hyperalgesia (increased pain sensitivity). These benefits may persist for at least 72 hours after a single dose. NMDA antagonism may therefore facilitate a rapid transition to naltrexone by reducing discomfort, improving motivation, and ameliorating adaptations associated with drug dependence, such as craving and arousal.
The purpose of this trial is to assess the feasibility of NMDA antagonist-assisted naltrexone initiation in opioid dependent individuals. After administration of extended-release naltrexone, participants will be followed for 4 weeks, and transitioned to appropriate care subsequently (oral naltrexone, extended-release naltrexone).

Primary Outcomes
Secondary Outcomes
-
Subjective Opioid Withdrawal Scale (SOWS) is a scale out of 64 points assessing withdrawal severity that is administered serially, every several hours, over the course of the naltrexone initiation. The questionnaire assesses symptoms that the patient rates on a scale of 0 (not at all) to 4 (extremely). The difference in total (sum) scores between baseline and end-of-induction will be reported. Scores range from 0 to 64.
