Objective: To evaluate the effect of 6 months of treatment with paliperidone extended-release (ER) tablets on the sleep profile of patients with schizophrenia.
Methods: A total of 984 patients meeting the The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for schizophrenia who switched their antipsychotic to paliperidone ER were recruited from 61 sites in five countries in Southeast Asia. We recorded patient demographics and assessed sleep quality and daytime drowsiness using visual analog scales.
Results: Approximately 70% of patients completed the 6-month study. After the use of paliperidone ER, patients reported significantly better sleep quality (76.44 vs 65.48; p<0.001) and less daytime drowsiness compared with their baseline value (23.18 vs 34.22; p<0.001). Factors predicting sleep profile improvement were completion of the study and higher baseline Positive and Negative Syndrome Scale scores.
Conclusion: Paliperidone ER can help schizophrenia patients to improve sleep quality and reduce daytime drowsiness; this was seen especially in the patients who completed the 6-month treatment period and had higher baseline Positive and Negative Syndrome Scale scores.
