title: Aripiprazole possibly worsens psychosis.
abstract: Aripirazole is a novel antipsychotic that functions as a partial agonist at the dopamine D2 receptor and, thus, might theoretically worsen psychosis. We report a series of four clinical cases of exacerbation of psychosis related to initiation of aripiprazole therapy. Cases 1 and 2 demonstrated the worsening of psychosis following initiation of aripiprazole (15-30 mg daily) while tapering off the previous atypical antipsychotic. Cases 3 and 4 demonstrated worsening of psychosis following the addition of aripiprazole (15-30 mg daily) to an atypical antipsychotic. In two out of the four cases, discontinuation of arpiprazole resulted in improvement of psychotic symptoms. Although the cases presented are suggestive of a relationship between initiation of aripiprazole therapy and worsening of psychosis, further research is needed to clarify any potential association.
