Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to determine if the known differences in genes influence drug metabolizing enzymes and receptors that are involved in risperidone drug action. The study will determine if differences in these genes will change the concentration of risperidone in the blood over time in children in relation to side effects and clinical response to risperidone.
