The development of atypical antipsychotics has stimulated research on the treatment of mania. Several well-established options now exist for monotherapy of mania. None of the atypicals has shown greater efficacy than haloperidol in improving manic symptoms, but they all produce fewer extrapyramidal side-effects and they may differ in their effects on depressive symptoms. Combinations of an antipsychotic with lithium or valproate offer further options, with somewhat greater efficacy in treating mania but also with more side-effects.
