Response of psychotic depression subtypes to pharmacotherapy.

Patients with psychotic depression respond well when treated with a combination of an antidepressant and antipsychotic medication. We previously reported that they will respond in a similar fashion when treated with amoxapine monotherapy. There are few prospective studies on the pharmacologic treatment response of psychotic depression subtypes. We treated 37 inpatients, 21 with mood congruent (MC) psychotic depression and 16 with mood incongruent (MI) psychotic depression, in a randomized double-blind fashion with either the combination of amitriptyline and perphenazine or with amoxapine for 4 weeks. Depression and psychosis ratings improved in a similar manner in both the MC or MI patients irrespective of medication treatment group. Global response rates were similar in the MI patients and MC patients. The data suggest that classifying psychotic depression into MC versus MI subtypes may have limited acute prognostic value in pharmacotherapy response rates.
