Brief Summary:
The purpose of this study is to assess the usefulness of the Risperdal® Consta® Treatment Guidebook in helping the doctor switch the adult patient from taking risperidone tablets daily by mouth to taking long-acting risperidone by injection. The study will also evaluate the effectiveness and safety of long-acting risperidone and its effect on patient satisfaction.

Condition or disease Intervention/treatment Phase
Schizophrenia Psychotic Disorders Drug: risperidone Phase 3

Detailed Description:
Many patients who take oral medication to treat schizophrenia or schizoaffective disorder have trouble taking their medication every day. They may not want to take it, or they may just forget. Risperidone injections, given once every 2 weeks, are expected to be just as effective as risperidone tablets taken once a day. The option of getting an injection every 2 weeks rather than taking a tablet every day may help patients keep to their medication administration schedule and could help to reduce the symptoms of their disease. The study will assess the usefulness of the Risperdal® Consta® Treatment Guidebook in a Community Mental Health Center setting, over a period of three months. This Guidebook was designed to help doctors switch adult patients from oral risperidone tablets to long-acting risperidone given once every 2 weeks by injection. During the study, patients will continue to take oral risperidone for 2 weeks following initiation of risperidone injections, which will be given every 2 weeks during a 12-week period. Physical examinations and laboratory tests will be performed to test the safety of the risperidone injections. Both the patient and the doctor will be asked questions about the usefulness of the guidebook and the effectiveness of the injections. The objective of this study is to demonstrate the effectiveness of the Risperdal® Consta™ Treatment Guidebook in switching patients with schizophrenia and schizoaffective disorder from daily oral risperidone to long-acting risperidone injections. In addition, safety evaluations are assessed throughout the study. Risperidone oral tablets, 2 to 6 milligrams per day for the first 2 weeks after initiation of long-acting risperidone injections; long-acting risperidone injections are given in doses of 25, 37.5, or 50 milligrams per 2 milliliter injection once every 2 weeks for 12 weeks.
