Abstract: Objective To observe the effect of various dosages of Risperidone Tablets in treatment of first episode schizophrenia and safety evaluation. Methods Patients (127 cases) with first episode schizophrenia from Beijing Fangshan District Mental Health Care Hospital from April 2012 to April 2014 were randomly divided into high-dosage group ( 62 cases) and low-dosage group (65 cases). The patients in the high-dosage group were po administered with Risperidone Tablets 0.5—1 mg/d at beginning, then gradually added to 6 mg/d according to patient's condition and adverse reactions in the second and third day, and maintained the dosage of 6 mg/d. The patients in the low-dosage group were same to those in the high-dosage group except added dosage and maintenance dosage of 3 mg/d. Two groups were treated for 8 weeks. After treatment, the efficacy was evaluated, and PANSS score, EPS occurrence and TESS scores in two groups were compared. Results The efficacies in the high-dosage and low-dosage groups were 93.85% and 82.26%, respectively, and there were differences between two groups (P < 0.05). After treatment, negative symptom scale scores, positive symptom scale score, the psychopathology scale scores, and PANSS total score in two groups were significantly lower, and the difference was statistically significant in the same group (P < 0.05). The observational indexes of the low-dosage group were significantly lower than those in the same period in the high-dosage group treated for 4 and 8 weeks, with significant difference between two groups (P < 0.05). The incidence of EPS and TESS scores at 4 and 8 week in the low-dosage group were obviously lower than those in the high-dosage group, and the difference was statistically significant between two groups (P < 0.05). Conclusion Low-dosage of Risperidone Tablets has curative effect in treatment of first episode schizophrenia with better clinical efficacy, less PANSS score, incidence of EPS, and TESS scores, which be superior to clinical effects of high-dosage of Risperidone Tablets.
