[Pharmacotherapy in personality disorders].
Subjects with personality disorders represent a relevant subset of the clinical psychiatric population and, to an even bigger extent, a comorbid condition to an axis-I diagnosis. Personality disorders appear to be difficult to treat and problematic in the therapeutic setting, and a pharmacologic treatment often does not follow recommendations from empirical studies. Psychopharmacologic drugs are able to modify the expression of certain personality dimensions, which are mainly disorder-related variables of temperament. Modern pharmacotherapy of personality disorders has a neurobiological basis. This is underlined by evidence from animal studies and can be associated with certain receptor-specific functions in humans. Treatment is consequently symptom-related and not specific for any disorder. It must be stressed that certain features but not the entire personality can be modified by drug treatment. Data from drug studies are still relatively scarce. An overview of studies on personality disorders is presented including information on dosages and augmenting strategies. Psychotherapy still is the basic treatment for personality disorders. However, psychopharmacological interventions should not only be considered when psychotherapy has failed. Treatments should be complementary from the start. There is a rationale for short- and long-term treatment. The latter is indicated, despite of the scarcity of data, when longer lasting and severe affective symptoms emerge. Response rates vary among the trials and appear to be lower than in non-comorbid axis-I disorders. A treatment algorithm is presented.
