Factors influencing plasma concentrations of ethosuximide.

Abstract:

:The relation between steady-state plasma ethosuximide level and drug dose was studied in 46 patients. In this population, plasma drug levels were proportional to drug dose, expressed on a body weight basis. Age did not alter this relationship, but plasma levels increased more rapidly, relative to dose, in females than in males. Intake of methylphenobarbitone, but not intake of certain other anticonvulsants (phenytoin, phenobarbitone, primidone and carbamazepine) altered the relationship between plasma ethosuximide level and ethosuximide dose. In individual patients, successive dose increments of equal size produced progressively greater increases in steady-state plasma ethosuximide levels. This phenomenon has obvious therapeutic implications.
