Olanzapine Versus Placebo in the Treatment of Borderline Personality Disorder.
Background: Atypical antipsychotics are increasingly used in clinical practice in the management of borderline personality disorder (BPD), and a small but growing body of literature supports their efficacy. Here, we report the results of a double-blind, placebo-controlled study of olanzapine as a treatment for BPD.
Method: Forty BPD patients (25 female, 15 male)
were randomly assigned in equal numbers to olanzapine and
placebo. Diagnoses were made using the Structured Clinical
Interview for DSM-IV Axis II Personality Disorders and the
Mini-International Neuropsychiatric Interview. Patients with
schizophrenia, bipolar disorder, or current major depression were
excluded. Olanzapine dosage was flexible, and the dose range was
2.5 to 20 mg/day, with most patients receiving 5 to 10 mg/day. No
concomitant psychotropic medications were allowed. Patients were
assessed at baseline and at 2, 4, 8, and 12 weeks. The primary
outcome was change in the total score for the 9 BPD criteria on a
1-to-7 Likert scale, the Clinical Global Impressions scale
modified for borderline personality disorder (CGI-BPD), using an
of covariance model including baseline score as
covariate. Data were collected from July 2000 to April 2002.
Results: Olanzapine was found to be significantly (p < .05) superior to placebo on the CGI-BPD at endpoint, with separation occurring as early as 4 weeks. Similar results were found for the single-item Clinical Global Impressions scale. Weight gain was significantly (p = .027) greater in the olanzapine group.
Conclusions: This study supports the efficacy of olanzapine for symptoms of BPD in a mixed sample of women and men. Further studies with olanzapine and other atypical antipsychotics are needed.
