Comparative efficacy and acceptability of antimanic drugs in acute mania: a multiple-treatments meta-analysis.
This meta-analysis found that antipsychotics (risperidone, olanzapine, and haloperidol) were significantly more effective than mood stabilizers in treating acute mania. Olanzapine, risperidone, and quetiapine had the lowest dropout rates.
- Multiple-treatments meta-analysis of 68 randomised controlled trials (n=16,073) comparing treatment of acute mania in adults with: aripiprazole, asenapine, carbamazepine, valproate, gabapentin, haloperidol, lamotrigine, lithium, olanzapine, quetiapine, risperidone, topiramate, and ziprasidone.
- Primary outcomes: mean change in rating scales and number who dropped out at 3 weeks.
- Haloperidol, risperidone, olanzapine, lithium, quetiapine, aripiprazole, carbamazepine, asenapine, valproate, and ziprasidone were significantly more effective than placebo.
- Haloperidol was significantly more effective than all other agents, with the exceptions of risperidone and olanzapine.
- Olanzapine, risperidone, and quetiapine were associated with significantly fewer discontinuations than lithium, lamotrigine, topiramate, gabapentin, or placebo.
- Gabapentin, lamotrigine, and topiramate were not significantly more effective than placebo.
