Background: The literature on the treatment mixed episodes in Bipolar Disorder [BD] is sparse. Second generation antipsychotics [SCA] have documented efficacy in mania, but not mixed episodes. The objective of this meta-analysis was to ascertain the efficacy of SGA, either as mono- and/or adjunctive therapy, in the treatment of acute mixed episodes of BD, compared to placebo. Methods: A MEDLINE search for English language publications of randomized controlled trials [RCTs] comparing SGA with placebo in the treatment of an acute manic/mixed episode of BD, during the period 1990-2012, was performed using the terms 'atypical antipsychotics', 'SGA', 'mixed episodes mania' and each SGA independently. 9 RCTs reporting data on 1289 mixed episode patients treated with aripiprazole, asenapine, olanzapine, paliperidone-ER, risperidone, and ziprasidone, either as monotherapy or as adjunctive therapy, versus placebo, for 3-6 weeks, were included in the meta-analysis. We extracted data on the number of patients, SGA, duration of study and mean change in mania and depression scores from baseline to endpoint. Standardized mean difference between SGA and placebo for the mean baseline-to-endpoint change in mania and depression rating scores was calculated, with a 95% confidence limit. Results: SGA, either alone or in combination with mood stabilizers, had superior efficacy in treating manic symptoms of mixed episodes compared to placebo (-0.41, 95% CI -0.53, -0.30; overall effect p < 0.00001). SCA were equally effective for manic symptoms in mixed episodes and pure mania (p=0.99). SCA had superior efficacy in treating depressive symptoms of mixed episodes (-0.30, 95% CI -0.47, -0.13; p < 0.001) compared to placebo in two trials reporting this information. Limitations: Thirteen relevant studies could not be included as data for mixed episodes were not presented separately. Conclusions: SGA are effective in treating acute mixed episodes of BD, with predominant manic symptoms. Their efficacy in treating depressed mixed episodes remains unclear. (C) 2013 Elsevier B.V.
