Paliperidone, the C-9 hydroxylated active metabolite of the antipsychotic agent risperidone, is the newest atypical antipsychotic to join the market following the introductions of olanzapine (ZyprexaTM), risperidone (RisperdalTM), quetiapine(SeroquelTM), and ziprasidone (GeodonTM). Compared to its parent, paliperidone has improved PK properties and a reduced potential for drug interactions. In terms of receptor affinity, the two drugs are equipotent.
