An open trial of olanzapine in the treatment of patients with psychotic depression.
Compared to major depression without psychosis, psychotic depression often responds poorly to treatment with tricyclic antidepressants alone. Atypical antipsychotics, which appear to possess thymoleptic properties, may represent a new treatment alternative for patients with psychotic mood disorders. This open-label, pilot study evaluated the efficacy of olanzapine monotherapy in patients with psychotic depression. Seven inpatients who met DSM-IV criteria for a major depressive episode (unipolar) with psychotic features participated in a 10-week open-label trial of olanzapine 10-20 mg/day. The Hamilton Rating Scale for Depression (HRSD), the Scale for the Assessment of Positive Symptoms (SAPS), and the Clinical Global Impression Scale (CGI) were performed at each visit to evaluate clinical response. Four out of the 5 study completers responded during the trial. Overall, there was a statistically significant change between baseline and final visit on the SAPS, HRSD, and the CGI Scale (p < .001). The results of this pilot study suggest that olanzapine may be an effective treatment for some patients with unipolar psychotic depression. However, these observations require replication in randomized, controlled trials.
