Paliperidone (sold as INVEGA, INVEGA Sustenna), also known as 9-hydroxyrisperidone, is an atypical antipsychotic developed by Janssen Pharmaceutica. Invega is an extended release formulation of paliperidone that uses the OROS extended release system to allow for once-daily dosing. Invega Sustenna (paliperidone palmitate) is a long-acting injectable formulation of paliperidone indicated for once-monthly injection after an initial titration period. Chemically, paliperidone is one of many active metabolites of the older atypical antipsychotic risperidone (paliperidone is 9-hydroxyrisperidone, i.e. risperidone with an extra hydroxyl group). It is indicated for the acute and maintenance treatment of schizophrenia.
