Requip is extensively metabolized in the liver. The main metabolic pathway is through hydroxylation of risperidone to 9-hydroxyrisperidone via the enzyme CYP2D6.

The main metabolite, 9-hydroxyrisperidone, has similar pharmacological activity to risperidone. Therefore, the clinical effects of the drug results from the combined concentrations of risperidone plus 9-hydroxyrisperidone active moiety.
