Oral vs Extended-Release Injectable Naltrexone for Hospitalized Patients With Alcohol Use Disorder: A Randomized Clinical Trial.
Summary
The specific aims of this pragmatic randomized controlled trial are to compare initiating injectable extended release naltrexone (XR-NTX) or oral naltrexone (PO-NTX) at the time of discharge from a medical hospitalization for patients with alcohol use disorder (AUD) on: 1) alcohol consumption and consequences, and 2) acute healthcare utilization (including hospital readmission and emergency visits) and cost-effectiveness. In exploratory analyses, the investigators will assess moderators of medication effects including demographic, behavioral, and genetic factors.
