Brief Summary
The goal of this clinical trial is to determine the efficacy of baclofen for the treatment of alcohol use disorder (AUD) in patients with or without comorbid anxiety symptoms. The main questions it aims to answer are:
- Do we see more abstinent days after the study period in patients with high anxiety symptoms compared to low anxiety symptoms?
- Do we observe additional differences between patients with high- and low anxiety symptoms in: any drinking at the end of treatment (yes/no), number of patients who respond to treatment, anxiety score reduction, autonomic responses, craving scores, drinking motives and side effects? Participants already taking baclofen as part of routine clinical care for treatment of AUD will be asked to answer several questionnaires over a 6 week study period.
