INTRODUCTION: Schizoaffective disorder (SCA) is a complex mental illness characterized by psychosis and affective symptoms. Treatment usually involves concomitant treatment with antipsychotics, mood stabilizers, and/or antidepressants. Effective treatment must address acute symptoms, maintain long-term stability, promote recovery, and improve patient functioning. Areas covered: Data from 3 pivotal studies evaluating the acute and maintenance treatment of SCA with paliperidone are reviewed. Two formulations of paliperidone have been studied for these indications: an extended-release oral formulation (NCT00397033, NCT00412373) and long-acting injectable once-monthly paliperidone palmitate (NCT01193153). The reported effects of these formulations on psychotic, depressive, and manic symptoms are discussed. Expert opinion: Both formulations were found to be safe and effective for the acute and maintenance treatment of SCA. Of critical importance for this treatment population is that rapid improvement was seen in all major symptoms of SCA, including psychosis, depression, and mania. Mediation analyses suggest that the known antipsychotic effects of paliperidone occur independently of its antidepressant effects. Both formulations of the drug are effective when used as monotherapy or adjunctively with antidepressants or mood stabilizers. Beyond symptom control, both formulations improved patient functioning and increased patient satisfaction.
