Therapeutic Effects on Single and Repeated - Dose Administration of Clonazepam for Seizure in Children / 实用儿科临床杂志

ABSTRACT

Objective To explore the change of degrade of clonazepam in serum with single and repeated - dose administration in children with seizure, and find a reasonable method for using the clonazepam. Methods Children with seizures were divided into single - dose paradigam, repeated - dose paradigam, and decreased - dose paradigam. The concentration of CZP in serum was determined by high performance liquid chromatography( HPLC). Results The serum concentrations of clanazepain in single - dose paradigam were (101.9?12.1),(76.9 ? 5.8),(50.7?2.9),(30.9?5.4),(21.5?6.8)?g/L,the time point that the blood samples collected were 15,30,60,120 and 480 min. The serum concentrations in repeated - dose paradigam were (97. 2 ? 6. 1),(130.4? 13. 4), (99. 4 ? 9.8),(79.6?2.4)?g/L,in decreased-dose paradigam were( 101.1 ?13.1),(123.1 ?6. 6), (99.4 ?9. 8), (79. 3 ? 2. 2)?g/L,in these two groups,the time point were 15,45,60 and 120 min. Conclusion Repeated administration of CZP with decreased dose may increase its effectiveness in treatment without substantially increasing toxicity.
