Risperdal is an atypical anti-psychotic drug that is used for treating symptoms of bipolar mania, schizophrenia, and autism. Risperdal contains risperidone, an atypical antipsychotic belonging to the chemical class of benzisoxazole derivatives. Risperdal was approved by the United States Food and Drug Administration (FDA) in 1993 for the treatment of schizophrenia.

Like any other anti-psychotics, it is believed that risperidone interferes with  the communication in the nerves of the brain. Communication among nerves takes place by the release of chemicals called neurotransmitters. The neurotransmitters travel to nearby nerves where they attach to receptors on the nerves. Risperidone blocks receptors on nerves like dopamine type 2, serotonin type 2, and alpha 2 adrenergic receptors. Risperdal is available in the form of tablets, oral solution and in powdered form form for injection.
