Guidelines for treating epilepsy in the age of felbamate, vigabatrin, lamotrigine, and gabapentin.
For the first time in 15 years, new antiepileptic medications are available for the treatment of patients with seizure disorders. These drugs have demonstrated efficacy in animal models of epilepsy and in controlled clinical trials. Felbamate was licensed in 1993 for use as adjunctive therapy or monotherapy in adults with partial or tonic-clonic seizures and as adjunctive therapy for children with the Lennox-Gastaut syndrome. Gabapentin was approved January 1994 as adjunctive therapy in patients 12 years or older with partial seizures, with or without secondary generalization. Lamotrigine is expected to be approved this year for the treatment of partial and tonic-clonic seizures in adults. Last, a new drug application has been filed for vigabatrin this year, with possible licensing next year. These four anticonvulsants present new options in the treatment of patients with refractory epilepsy and are not merely congeners of previously available treatments. They have unique clinical spectrums and are reported to be safer and better tolerated than conventional therapy. Trials to compare their use with that of conventional therapy have not been done, and their use in the initial treatment of patients with epilepsy is not completely clear.
