Abstract

Introduction

Early stages after a first psychotic episode (FEP) are crucial for the prognosis of the disease. Those patients who drop out of treatment after a FEP show a significant increase in their vulnerability to relapse. Relapses associated a greater risk of neurotoxicity, chronicity, hospitalization, decrease of response to the treatment, increase of burden and functional decline.

Objectives

To determine what antipsychotic is more effective in the prevention of relapse after a first psychotic episode.

Material and methods

PAFIP is an assistance program focused on early intervention in psychosis. Between January 2001 and January 2011, 255 patients were recruited and randomly assigned to treatment with haloperidol (n = 48), olanzapine (n = 41), risperidone (n = 44), quetiapine (n = 34), ziprasidone (n = 38) and aripiprazole (n = 50). We compared the rates of relapse and remission reached by haloperidol, olanzapine, risperidone, aripiprazole, ziprasidone and quetiapine during a 3-year follow-up. All of the patients were antipsychotic naives at the beginning of the treatment.

Results

There were no statistically significant differences in regard to the rate of clinical remission. Patients assigned to the groups of aripiprazole, olanzapine and risperidone presented a solid trend to a significantly inferior rate of discontinuation for any reason since the beginning of the treatment.

Conclusions

These data point to a greater protection against relapse and a likely better prognosis related to the use of aripiprazole, Olanzapine and risperidone.
