Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Medication is the most efficacious treatment of an opioid use disorder, including methadone, buprenorphine, and naltrexone. However, many patients experience withdrawal symptoms, which prevents them from being successfully inducted onto medication for opioid use disorder. This study is a pilot study investigating whether blocking the SPG helps reduce withdrawal symptoms in OUD. This study does not involve treatment or induction onto medications. It is a proof of principal study only. We will recruit non-treatment seeking subjects with OUD who are admitted to the research unit for all procedures.
