Summary
The purpose of this study is to evaluate improvement and efficacy of paliperidone extended-release for subjective well-being and drug attitudes of participants, when switching from oral antipsychotics in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).
Eligibility Criteria
Inclusion Criteria
- Participants who are diagnosed with schizophrenia (diagnosis criteria: Diagnostic and Statistical Manual of Mental Disorders, fourth edition [DSM-IV])
- Participants who need to change the antipsychotic drug to another one for the following reasons among the participants treated with an antipsychotic drug for more than two weeks before the screening-Lack of efficacy, lack of tolerance or lack of compliance
- Participants who are capable of and willing to fill out the questionnaire for themselves
- Childbearing potential women who consent to the use of the consistently permissible contraception (oral contraceptive, contraceptive injection, intrauterine device, double barrier method and contraceptive patch)
- Participants who are compliant with self-medication or can receive consistent help or support
Exclusion Criteria
- Participants with the past history of neuroleptic malignant syndrome (NMS), or with allergy or hypersensitivity to risperidone or paliperidone
- Participants who have taken clozapine within one month before screening
- Participants who are suspicious of having clinically significant risk including suicide or aggressive behavior and are expected to unable to complete the study (based on the investigator's judgment)
- Participants with severe preexisting gastrointestinal narrowing (pathologic or iatrogenic) or participants who cannot swallow the drug whole (The study drug must not be chewed, divided, melted or grinded because it can impact the study drug release profile)
- Participants with a known or suspected history (for 6 months and longer) of substance dependence according to the DSM-IV criteria
