Abstract

Abstract Ethosuximide and phensuximide in plasma and urine can be assayed to a concentration of 2–5 μg ml−1 by a rapid and specific gas chromatographic assay. The method can be used to monitor plasma concentrations in patients with petit mal treated with these drugs alone or in combination with other antiepileptic drugs. The steady-state plasma concentrations of ethosuximide in children given 10–45 mg kg−1 day−1 varied between 10 and 150 μg ml−1 indicating marked interindividual differences in pharmacokinetics.
