Predischarge Injectable Versus Oral Naltrexone to Improve Postdischarge Treatment Engagement Among Hospitalized Veterans with Alcohol Use Disorder: A Randomized Pilot Proof-of-Concept Study.

Background: Injectable naltrexone for alcohol use disorders (AUDs) has been efficacious in several studies. It has not been (i) compared head-to-head with oral naltrexone or (ii) examined in the hospital setting as an intervention that might facilitate treatment attendance after hospital discharge.

Methods: Fifty-four hospitalized veterans identified as having DSM-IV-TR alcohol dependence were randomized to receive (i) a 50 mg oral naltrexone plus a 30-day prescription or (ii) a 380 mg intramuscular naltrexone injection prior to discharge.
