This study found that most patients with schizophrenia or schizoaffective disorder continued risperidone treatment. A slower dose titration and smaller dose increments improved treatment continuation rates.

Area of Science:

  • Pharmacology
  • Psychiatry
  • Clinical Pharmacy

Background:

  • Risperidone is a widely used antipsychotic for schizophrenia and schizoaffective disorder.
  • Optimal dosing strategies are crucial for treatment adherence and efficacy.

Purpose of the Study:

  • To evaluate the recommended dose schedule for risperidone.
  • To identify factors influencing treatment continuation with risperidone.

Main Methods:

  • Analysis of computerized pharmacy data for 1,283 inpatients diagnosed with schizophrenia or schizoaffective disorder.
  • Definition of risperidone continuance as 16 days of treatment or until discharge.

Main Results:

  • 84% of patients continued risperidone treatment.

  • Adherence to the recommended dose schedule decreased over time.
  • Higher maximum doses, longer time to reach maximum dose, and smaller dose increments (0.5-2 mg/day) were associated with better treatment continuation.

    • Conclusions:

    • The current recommended risperidone dose schedule may require modification.
    • A less rapid titration (6 days to 1 week) with dose increments of 0.5-2 mg/day is suggested to improve patient outcomes.
