Abstract:
Objective To explore the blood drug concentration monitoring of sustained-release valproate(DK)in children with epilepsy,focusing on the selection of sampling time and evaluation of the results.Methods Two hundred and seventy-one children taking DK and 155 children taking sodium valproate syrup(VPA Syr)were involved and their serum were taken when achieved steady state to determine the valproic acid level using fluorescence polarization immunoassay.They were divided into 4 groups,which were DK taken once daily group(DK qd group,126 children),DK taken once daily at night and sampled on morning group(DK qn group,26 children),DK taken every 12 h group(DK q12 h group,119 children),VPA Syr q12 h group(155 children).Determine the proportion of the blood drug concentration of each group below,ithin and above the therapeutic range for valproate(50-100 mg/L)were determined.The data were analyzed by t test.Results The Cmin of DK qd group were(73.09?19.91)mg/L,significantly lower from the serum concentration of DK qn and sampled on morning group [(94.94?25.44)mg/L](P0.05).Conclusions DK qn should sampled at night before the night dose.The Cmin of DK q12 h was higher according to the therapeutic range,it's favorable range still needs clinical practice.
