 The introduction of atypical antipsychotics, with a more favorable tolerance profile, increases clinicians options for treating BPD. Olanzapine has proven its efficacy in four double-blind, placebo-controlled clinical trials in patients with BPD. Ziprasidone is an atypical antipsychotic with a pharmacological action on serotonergic, dopaminergic and adrenergic receptors. It has proven to be effective for schizophrenia, schizoaffective and acute mania disorders and the incidence of side effects is low.
