    Abstract:
    AIMS: The goal of the present study was to evaluate the efficacy of risperidone combined with mood stabilizers for treating bipolar mixed state. METHODS: The present study was a 24-week, open-label, combination, prospective investigation of the efficacy of risperidone in combination with mood stabilizers. Risperidone (1-6 mg/day) was given in combination with mood stabilizers in flexible doses according to clinical response and tolerability for 114 patients in mixed or manic episode. RESULTS: Forty-four patients met our criteria for mixed state bipolar disorder and 70 met the criteria for pure mania. Mean age for the subjects was 39.0 +/- 11.0 years and 55.3% were female. The combination of risperidone with mood stabilizers significantly improved the scores on the Young Mania Rating Scale (YMRS), 17-item Hamilton Rating Scale for Depression (HAMD), 18-item Brief Psychiatric Rating Scale (BPRS), Global Assessment Scale (GAS), and Clinical Global Impression Scale for use in bipolar illness Severity (CGI-BP) at 24 weeks (P < 0.0001). Analysis of the YMRS, BPRS, GAS, and CGI-BP scores showed significant improvement in both the manic and mixed groups. The rate of response in YMRS scores was 84.2% (n = 96) and the rate of YMRS remission was 77.2% (n = 88) at week 24 in the total population. Seventy-four patients met both YMRS < or = 12 and HAMD < or = 7 at week 24 (64.9%). Risperidone was well tolerated, and adverse events were mostly mild. CONCLUSION: The combination of risperidone with mood stabilizers was an effective and safe treatment for manic symptoms and coexisting depressive symptoms of bipolar disorder.
