ABSTRACT

Objective To evaluate the efficacy and effective time of low dosage of olanzapine combined with fluoxetine in treatment of major depression. Methods A total of 53 patients who suffered from major depression diagnosed according to CCMD-3 and the score of Hamilton rating scale for depression (HAMD) over 28, were randomly divided into 2 groups alprazolam group (0.4 mg alprazolam, 2/d and 20 mg fluoxetine, 1/d), olanzapine group (2.5 mg olanzapine, 1/d, and 20 mg fluoxetine, 1/d). The treatment period lasted six weeks and the subjects were evaluated by using HAMD and HAMA at week 1, 2, 4, 6. The effective time was estimated by decreasing rate of the scale of HAMD and the amelioration of sleep disturbance and anxiety/somatization in HAMD were observed before and during the treatment. Results The therapeutic effects in olanzapine group at week 1 were observed with the apparent rate of 67%. The scores of HAMD and HAMA in olanzapine group were obviously lower than those in alprazolam group at each time point. The sleep disturbance and anxiety/somatization of the patients in olanzapine group improved significantly as compared with those in alprazolam group. Conclusion Fluoxetine combined with olanzapine is a fast and effective method to treat major depression.
