| Measure | Time frame |
|---|---|
| Main Objective: Due to Quetiapine’s particulars and the promising receptor profile, we want to examine the efficacy concerning relapse prevention of alcoholics suffering from persisting craving and/or affective symptoms (persisting sleep disorder, persisting excitement, persisting depressive symptoms, persisting anxiety symptoms) in comparison to matching placebo in a double-blind pilot study.;Secondary Objective: Evaluation of safety and tolerability of Quetiapine. We further want to compare the course of the above mentioned craving and affective symptoms under medication with quetiapine / matching placebo. ;Primary end point(s): Time to first severe alcohol relapse in quetiapine treated compared to placebo treated patients. | — |
