Felbamate is an anticonvulsant drug used for the treatment of partial seizures in persons above 14 years of age. This assay is useful for determining whether a poor therapeutic response is attributable to non compliance or lack of drug effectiveness. It also monitors changes in serum levels due to interactions with coadministered drugs like Barbiturates and Phenytoin.
