摘要

Remacemide hydrochloide,a novel anticonvulsant agent,adn ists major active metabolite,desglcinylremacemide,were measured simultaneously in brain tissue by high-performance liquid chromatography with UV detection.Intra-and inter-assay variations for remacemide (1,5,10 #mu#g/ml) were 5.1 ,10.5 and 3.1,4.0 and 1.3% ,respectively.Intra-and inter-assay variations for desglycinylremacemide (1,5,10 #mu#g/ml) were 4.23 ,3.8 and 8.4% and 7.9 ,8.8 and 3.1%,respectively.Limits of detection and quantification for both analytes were 4 and 31 ng/ml,respectively,with recovery consistently >=85%.This reliable assay has applications in the pre-clinical neuropharmacokinetic and neuropharmacodynamci investigation of remacemide hydrochloride.
