Abstract:
OBJECTIVE To investigate the efficacy and safety of domestic Paliperidone extended-release tablets as a substitute for original Paliperidone extended-release tablets in the treatment of stable schizophrenia. METHODS A total of 65 patients with schizophrenia， who were treated with single original Paliperidone extended-release release tablets for 2 months or more in the outpatient or inpatient department of Shandong Daizhuang Hospital from June 2021 to June 2022， were collected and randomly divided into the domestic group （33 cases） and the original group （32 cases）. The domestic group was treated with the same dose of domestic Paliperidone extended-release tablets instead for 2 months， and the original group continued to use the previous dose of the original drug for 2 months. Positive and negative syndrome scale （PANSS） and treatment emergent symptom scale （TESS） were used to evaluate the two groups at the time of enrollment and the end of 1 week， 1 month and 2 months after enrollment. The incidence of ADR was calculated at the end of 2 months after enrollment. The fasting blood glucose， blood lipid indicators （triglyceride， total cholesterol， low-density lipoprotein， high-density lipoprotein， very-low-density lipoprotein）， serum prolactin levels， and paliperidone blood concentration were determined after the intravenous blood sample was collected. The ratio of paliperidone blood concentration to dose （C/D value） was calculated， and an electrocardiogram was performed. RESULTS There were 31 and 30 patients in the domestic group and the original group who completed the trial， respectively. There were no statistical significances in PANSS score， TESS score or C/D value at the time of enrollment and the end of 1 week， 1 month and 2 months after enrollment； there were no statistical significances in the levels of fasting blood glucose， blood lipid or serum prolactin at the time of enrollment and at the end of 2 months after enrollment （P＞0.05）. PANSS scores of both groups significantly decreased at the end of 1 month and 2 months after enrollment （P＜0.01）. The incidences of ADR were 25.81% in the domestic group and 30.00% in the original group， without significant difference （P＞0.05）， and there were no significant abnormalities in the electrocardiograms of the two groups. CONCLUSIONS Domestic Paliperidone extended-release tablets can directly replace the original tablets in the treatment of stable schizophrenia， and their clinical efficacy and safety are comparable.
