[Drug therapy of patients with emotionally unstable personality].
BACKGROUND
Most patients with borderline personality disorders are treated with psychotropic medication. There are, however, no clear clinical guidelines concerning optimal treatment of the disorder.


METHODS
This article reviews the data on the efficacy of treatment with different classes of psychopharmacological drugs. The emphasis is on clinical trials published after 1981, as most placebo-controlled double-blind studies have been done in the last two decades. Furthermore, studies conducted before 1980 are more difficult to interpret because of changes in clinical diagnostic criteria.


RESULTS
Neuroleptics have been studied most extensively followed by antidepressants. Neuroleptics have a modest, but broad therapeutic effect on symptoms in all domains. Doses are lower than those used for treating schizophrenia. Antidepressants have a more inconsistent effect. Tricyclics have been the least successful, whereas irreversible MAO inhibitors and selective serotonin reuptake inhibitors (SSRIs) have been effective in treating mood symptoms and impulsivity. Lithium has a possible effect in diminishing anger and suicidal symptoms.


CONCLUSIONS
As there is no "drug of choice" for the treatment of borderline personality disorder, a more rational clinical approach might be to treat different symptom clusters (cognitive/schizotypal, affective, impulsive) rather than the disorder itself. Finally, some practical guidelines for drug treatment of the disorder are proposed.
