title: Liquid chromatographic determination of serum levels of d,l-4-amino-N-(alpha-methylbenzyl)-benzamide, a new benzamide anticonvulsant.
abstract: A method for the high-performance liquid chromatographic (HPLC) determination of serum concentrations of d,l-4-amino-N-(alpha-methylbenzyl)-benzamide and its N-acetylated metabolite is described. The compounds are isolated from a 50-microL sample of serum using solid phase extraction. The compounds and internal standard are eluted from the extraction column with acetonitrile. Quantitation is performed via UV detection at 275 nm following isocratic reversed-phase (C18) separation using a ternary solvent system. The assay procedure is useful for the determination of concentrations of parent compound from 0.63 to 87.9 micrograms/mL from 50 microL of serum.
