Patients must be clinically stable on antipsychotic medications other than risperidone or paliperidone or clozapine for at least 4 weeks prior to screening, based on clinical assessments AND a Positive and Negative Syndrome Scale (PANSS) total score less than or equal 70 at Screening Visit 4. Patients with a Body Mass Index in range of 18.0 to 35.0 5. Patients with an Informed Consent Form signed by the patient or legally authorized representative

Exclusion criteria

1. Patients with a mental disorders other than schizophrenia or schizoaffective disorder, according to the DSM-IV-TR 2. Patients who received oral risperidone or paliperidone or clozapine within 14 days prior to screening, or Risperdal® Consta® within 100 days prior to screening or paliperidone palmitate within 10 months prior to screening 3. Patients with neuroleptic malignant syndrome or physical fatigue associated with dehydration or malnutrition 4.

Patients with uncontrolled diabetes mellitus as indicated by a HbA1c level greater than or equal to 7% 7. Patients with a history of or currently having epilepsy or convulsion disorders 8. Patients who have had electroconvulsive therapy within the past 2 months prior to screening 9. Patients who used medication known to be an inducer or inhibitor for CYP 2D6 within 2 weeks prior to screening 10. Patients with a history of allergic reaction to risperidone or to the excipients of LY03004 11. Patients who have met DSM-IV-TR criteria for substance abuse or dependence with the exception of caffeine or nicotine in the past 6 months prior to screening 12.
