BACKGROUND:Obsessive-compulsive disorder (OCD) is a chronic disorder with unknown etiology. Failure in OCD treatmentcompulsive is common and finding effective augmentations in treatment of OCD will benefit patients. Antipsychotic augmentation is a common strategy for treatment resistant OCD. This trial evaluated the efficacy of adding aripiprazole in patients whose OCD was insufficiently responsive to an adequate SSRI treatment. METHODS:Thirty-nine adult outpatients, who met the DSM-IV-TR criteria for OCD and had treatment resistant OCD were evaluated in a double-blind randomized clinical trial. The patients received either aripiprazole 10 mg/day or placebo, for 12 weeks. Data were analyzed using intention-to-treat analysis with last observation carried forward. All statistical tests were two-sided, and were considered statistically significant at P < 0.05. RESULTS: A significant reduction in total scores of Y-BOCS (P < 0.0001) was found in the aripiprazole group. Aripiprazole was generally well tolerated. There was no significant difference between the two groups in terms of observed side effects. CONCLUSION: Results of the present study indicate that aripiprazole could be an effective augmentation medicine in treatment resistant OCD.
