European Drug Utilization Study - EUDUS

The purpose of this retrospective observational study is to evaluate the characteristics of patients receiving Seroquel XR as treatment for their Major Depressive Disorder. The study will also investigate how the medication is used for these patients and if there are any differences in drug utilisation between the included countries. The study is observing patients initiating Seroquel XR during a 9 month period corresponding to 3 to 12 months following the launch of the product in each country for the MDD indication. A drug utilisation questionnaire will be used to collect study data from patients' medical records.
