Official title

Treatment of Major Depressive Disorder With Psychotic Features With Quetiapine Monotherapy; Quetiapine and Citalopram; or Haloperidol and Citalopram

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to examine the mood stabilizing and antipsychotic properties of quetiapine in the treatment of depression by comparing subjects who were randomly assigned to either quetiapine monotherapy, quetiapine and citalopram; or haloperidol and citalopram. We hypothesize that quetiapine monotherapy would have similar effects to the combination of a first generation antipsychotic plus an antidepressant for the treatment of a major depressive episode with psychosis.
