OBJECTIVES: The aim of this study was to compare the outcomes of olanzapine- and valproate-treated patients in an observational study of acute mania with the results of a randomised controlled trial (RCT) assessing the same treatments. METHODS: EMBLEM (European Mania in Bipolar Evaluation of Medication) was a 2-year, prospective, observational study of health outcomes associated with the treatment of mania. Severity of mania and depression were assessed at baseline and 6 weeks using the YMRS and the 5-item version of the HAMD, respectively. RESULTS: 621 patients were analysed (n=107 valproate, n=514 olanzapine). Both groups improved from baseline to 6 weeks in mean YMRS and HAMD-5 total scores, with greater mean improvements in the olanzapine compared with the valproate group. Olanzapine was associated with more weight gain and less gastrointestinal difficulties than valproate. DISCUSSION: The EMBLEM results support those of the RCT, which suggest that olanzapine monotherapy seems to be more effective than valproate monotherapy in the treatment of acute mania.
