Antiepileptic drug therapy in the twenty first century.

ABSTRACT

In the last 25 years, particularly the last decade, there have been many advances relating to all aspects of epilepsy i.e. pathophysiology, diagnosis, pharmacotherapy and surgical interventions. Noteworthy has been the progress in terms of understanding of the established antiepileptic drugs (AEDs) and introduction of several newer agents developed rationally, on the basis of now available information on the biochemical changes in the epileptic brain. Data is accumulating regarding the use of newer agents but they still need to stand the test of time. Many of the newer AEDs may offer a better tolerability because of favorable pharmacokinetic characteristics and minimal drug interactions. However, serious adverse events have been associated with felbamate and lamotrigine already and for other newer agents reliable and accurate data needs to be generated.
