About this trial
The goal of this clinical trial is to investigate the effects of ketamine, in combination with standard inpatient addiction therapy, for adults with depression and alcohol use disorder. After screening and enrollment, participants will undergo baseline assessments of depression, measures of alcohol use and craving, as well as neurocognitive function. Participants will then be randomized to either ketamine (intervention) or midazolam (control). All participants will be admitted for standard inpatient addiction therapy while receiving ketamine or midazolam. Measures on safety, depression and alcohol use disorder will be repeatedly assessed during and after treatment. Final follow-up assessment is scheduled 6 months after baseline assessment.
