OBJECTIVE: Recent studies have focused on the role of inflammatory cascades as one of the possible etiologic factors of bipolar disorder. We hypothesize that celecoxib, through its anti-inflammatory properties, may have a therapeutic role in acute bipolar mania. PATIENTS AND METHODS: Forty-two adolescent inpatients with the diagnosis of acute bipolar mania participated in a parallel, randomized, double-blind controlled trial, and 40 patients underwent an 8-week treatment with either celecoxib (100 mg twice daily) or placebo as an adjunctive treatment to lithium and risperidone. Patients were evaluated using Young Mania Rating Scale (YMRS) at baseline and weeks 2, 4, and 8. The primary outcome measure was to assess the efficacy of celecoxib compared with placebo in improving mania symptoms. RESULT: General linear model repeated measures showed significant effect for time × treatment interaction on YMRS scores [F (2.54, 96.56) = 3.21, p = 0.03]. Significantly greater improvement was observed in YMRS scores in the celecoxib group compared with the placebo group from baseline YMRS score at week 8 (p = 0.04). Although a 35% greater response to treatment (considering a Clinical Global Impressions-Improvement score of ≤2, very much/much improved) was observed in the celecoxib group compared with the placebo group, the difference did not reach the statistical significance level (p = 0.09). No serious adverse event was reported. CONCLUSIONS:Celecoxib may be an effective adjuvant therapy in treatment of manic episodes (without psychotic features) of adolescents with bipolar mood disorder. The mood-stabilizing role of this drug might be mediated through its action on inflammatory cascades.
