Abstract
OBJECTIVES: The aim of this study was to describe the prevalence of the use and prescribing patterns of anti-seizure medications (ASMs) over a six-year period, and to provide real-world evidence on medicine utilization of pediatric patients with epilepsy in China. METHODS: ASM prescriptions for pediatric patients written from 2013 to 2018 were extracted from the database of the Hospital Prescription Analysis Cooperative Project. Trends of ASM use were analyzed by total prescriptions, cost, age, sex, ASM class and specific ASM. Prescribing patterns of ASMs were also analyzed. RESULTS: A total of 44,675 ASM prescriptions were extracted for analysis in this study. Throughout the study period, a slight increase of ASM prescriptions was observed from 6170 in 2013 to 8211 in 2018. Children aged between 6 and 18 years, accounted for 78 % of total prescriptions every year. ASM use in boys was about 1.5 times higher than that in girls. Newer ASMs were prescribed more than older ASMs during this period. Sodium valproate was the most frequently prescribed ASM in 2013, and its use decreased in girls in 2016. Levetiracetam increased from 19.10 % in 2013 to 28.09 % in 2018 and became the most common ASM at the end of this study. Meanwhile, the use of oxcarbazepine increased from 19.31 % to 22.04 %, whereas the use of lamotrigine had declined from 18.43 % to 10.72 %. Monotherapy (66.24 %) was more frequently used than combined therapy, which included dual combination (25.80 %) and triple or more combinations (7.96 %). CONCLUSION: There is an increased ASM prescription trend in childhood usage. Levetiracetam has replaced sodium valproate as the most frequently prescribed ASM in pediatric patients. Newer ASMs with fewer side effects and drug interactions are increasingly utilized, which is consistent with evolving recommendations by the medical community.
