| Objective To study a therapeutic reference range and laboratory alert level of amisulpride in the clinical treatment of schizophrenia.Methods Patients who met the diagnostic criteria for schizophrenia in the International Classification of Diseases， tenth edition （ICD-10） were enrolled， and all patients received amisulpride treatment. Data including age， gender， duration of treatment， single daily dose， clinical diagnosis， amisulpride concentration， the scores of the Scale for the Assessment of Positive Symptoms （SAPS）， Scale for the Assessment of Negative Symptoms （SANS） and Positive and Negative Syndrome Scale （PANSS）， the adverse reaction rate and multitherapy were collected. The concentration of amisulpride was compared within different efficacy groups and different dosage groups， meantime， the incidence rate of adverse reactions was compared within different amisulpride concentration groups， and between monotherapy and multitherapy groups. Thereafter， the therapeutic reference range and laboratory alert level of amisulpride in the clinical treatment of schizophrenia were explored via estimating the negative and positive predictive values.Results The amisulpride concentration yielded no statistical difference within different dosage groups and different efficacy groups （F=0.745， 1.343， P>0.05）. The single daily dose among patients in different efficacy groups demonstrated no significant difference （F=0.902， P>0.05）. The correlation between amisulpride treatment efficacy and its concentration denoted no statistical significance （r=0.023， P=0.744）. The clinical efficacy and adverse reaction rate showed no significant difference between monotherapy group and multitherapy group （F=2.198， 0.095， P>0.05）. The concentration of amisulpride was not linearly correlated with the adverse reaction rates ［y=100x/（78.13+x）， r=0.960］. When amisulpride concentrations ranged from 100 to 600 ng/mL， the mean reduction rate was equal to or above 42%， the effective detection rate of the reference cut-off value was equal to or above 1.485， and the incidence of adverse reactions was equal to or below 85%. When amisulpride concentrations ranged from 1400 to 1800 ng/mL， there was a decreasing trend in reduction rate （all<42%） and an increasing trend in adverse reaction rate （all>85%） as the concentration of amisulpride increased.Conclusion A reference range of 100~600 ng/mL and an alert level of 1400 ng/mL are recommended for the clinical safety of amisulpride. |
