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).
A trial of carbamazepine in borderline personality disorder.
Borderline personality disorder does not have a first choice pharmacological treatment. We studied 20 borderline inpatients in a double-blind parallel placebo-controlled trial with carbamazepine for a mean of 30.9 days. No significant positive effects of the drug were found.
