No studies involving risperidone were identified which randomly assigned treatment for long-term relapse prevention. Trials involving random assignment of risperidone and other treatments for long-term treatment are needed.
閱讀完整摘要
Risperidone, an atypical antipsychotic, is used to treat acute manic episodes, particularly when psychotic symptoms are present. Drugs used to treat mania are often continued as long-term treatment to prevent relapse. There is a need for evidence of the effectiveness and safety of risperidone as long-term treatment.
目的

Not applicable.
主要結果
No randomised trials comparing risperidone with other treatments for the prevention of manic and depressive relapses were identified.
作者結論
There is a need for randomised controlled trials comparing risperidone and other treatments for the prevention of relapse in bipolar disorder. The trials should involve randomisation of treatment for relapse prevention and involve long-term follow up.
