Abstract

Abstract An automated internal standard method for the determination of felbamate in 0.1 ml of plasma from pediatric and adult beagle dogs was developed. Plasma proteins are precipitated with acetonitrile and after centrifugation the supernatant is directly injected on a Spherisorb ODS2, 3 μm, 150 mm × 4.6 mm I.D. column with 25% acetonitrile in aqueous phosphate buffer, pH 6.50, as mobile phase with ultraviolet detection at 210 nm. The run time is 10 min, the linear range is 0.150–150 μg/ml felbamate, and the lower limit of quantitation is 0.150 μg/ml.
