BACKGROUND Evidence is limited regarding the most effective pharmacological treatment for psychotic depression :  combination of an antidepressant plus an antipsychotic , monotherapy with an antidepressant or monotherapy with an antipsychotic .
This is an up date of a review first published in 2005 and last up date d in 2009 .
OBJECTIVES 1 .
To compare the clinical efficacy of pharmacological treatments for patients with an acute psychotic depression :  antidepressant monotherapy , antipsychotic monotherapy and the combination of an antidepressant plus an antipsychotic , compared with each other and /or with placebo.2 .
To assess whether differences in response to treatment in the current episode are related to non-response to prior treatment .
Depressed in-patients respond differently to imipramine and mirtazapine.
Tricyclic antidepressants and more recent antidepressants are generally considered to have equivalent efficacy in the treatment of depression . After a previous report of a marked difference in the response to mirtazapine compared to imipramine , we report here an analysis of different symptom clusters . One hundred seven consecutive in- patients with major depression ( Diagnostic and Statistical Manual III-R , DSM-III-R ) and a Hamilton Rating Scale for Depression ( HRS-D ) score of 18 points or more were r and omly assigned to double-blind treatment . Two and four weeks after predefined blood levels had been obtained , the severity of depression was assessed using the HRS-D. The mean dosages used were 235 mg/day of imipramine and 77 mg/day of mirtazapine , the latter being in excess of the 15 - 45 mg/day range currently advised . Total HRS-D scores and seven symptom clusters were analyzed in the 85 patients ( 79 % ) who were not receiving any co-medication .  Imipramine was more effective against the clusters related to core symptoms of depression : " depression and guilt " , " retardation " , and " melancholia " , respectively . Mirtazapine showed a biphasic response with regard to the clusters " sleep " and " anxiety/agitation " , respectively , which consisted of a marked response after two weeks of predefined blood level , but with a waning of this effect at four weeks . Imipramine produced a more gradual response on these clusters , which was more pronounced at four weeks than with mirtazapine . Two aspects of the present study could be related to this finding : blood level control result ed in optimal treatment with imipramine but not mirtazapine , and - most importantly - the patients were not receiving any anxiolytic or hypnotic co-medication . These findings suggest that mirtazapine may have anxiolytic and sedative properties and fewer antidepressant properties than imipramine in severely depressed in- patients
