The available evidence indicates some beneficial effects with second-generation antipsychotics, mood stabilisers, and dietary supplementation by omega-3 fatty acids. However, these are mostly based on single study effect estimates. Antidepressants are not widely supported for BPD treatment, but may be helpful in the presence of comorbid conditions. Total BPD severity was not significantly influenced by any drug. No promising results are available for the core BPD symptoms of chronic feelings of emptiness, identity disturbance and abandonment. Conclusions have to be drawn carefully in the light of several limitations of the RCT evidence that constrain applicability to everyday clinical settings (among others, patients' characteristics and duration of interventions and observation periods).
Aripiprazole in the treatment of patients with borderline personality disorder: a double-blind, placebo-controlled study.
Aripiprazole is a relatively new atypical antipsychotic agent that has been successfully employed in therapy for schizophrenia and schizoaffective disorders. A few neuroleptics have been used in therapy for patients with borderline personality disorder, which is associated with severe psychopathological symptoms. Aripiprazole, however, has not yet been tested for this disorder, and the goal of this study was to determine whether aripiprazole is effective in the treatment of several domains of symptoms of borderline personality disorder.
                Subjects meeting criteria for the Structured Clinical Interview for DSM-III-R Personality Disorders for borderline personality disorder (43 women and 9 men) were randomly assigned in a 1:1 ratio to 15 mg/day of aripiprazole (N=26) or placebo (N=26) for 8 weeks. Primary outcome measures were changes in scores on the symptom checklist (SCL-90-R), the Hamilton Depression Rating Scale (HAM-D), the Hamilton Anxiety Rating Scale (HAM-A), and the State-Trait Anger Expression Inventory and were assessed weekly. Side effects and self-injury were assessed with a nonvalidated questionnaire.
                According to the intent-to-treat principle, significant changes in scores on most scales of the SCL-90-R, the HAM-D, the HAM-A, and all scales of the State-Trait Anger Expression Inventory were observed in the subjects treated with aripiprazole after 8 weeks. Self-injury occurred in the groups. The reported side effects were headache, insomnia, nausea, numbness, constipation, and anxiety.
                Aripiprazole appears to be a safe and effective agent in the treatment of patients with borderline personality disorder.
