Pharmacological Management of EpilepsyRecent Advances and Future Prospects

There is still a need for new antiepileptic drugs (AEDs) as the clinical efficacy, tolerability, toxicity or pharmacokinetic properties of existing AEDs may not be satisfactory. One new AED has recently been approved (rufinamide in 2007) and six others are in late-stage development (phase III and onwards) [brivaracetam, carisbamate, eslicarbazepine, lacosamide, retigabine and stiripentol]. The purpose of this review is to provide updated data on proposed mechanisms of action, efficacy and tolerability on these new AEDs, and to discuss the rationale for their development and possible advantages compared with existing treatment, based on recent publications and MEDLINE searches.
