Abstract
Importance of the field: Patients with epilepsy have recurrent unproved seizures. Epilepsy is common, with a prevalence range that centers at around 1%. Patients with epilepsy can have a poor quality of life and suffer significant social stigma. Despite the availability of a large number of antiepileptic drugs (AEDs) including standard and newer ones, a significant percentage of patients with epilepsy remain poorly controlled.
Areas covered in this review: In this review, we briefly summarize data on the available AEDs, then present current information on the emerging AEDs, including their chemical structure, pharmacology, mechanism of action, and efficacy and adverse event profile in clinical trials. The AEDs included are rufinamide, lacosamide, eslicarbazepine, retigabine, brivaracetam, ganaxolone, stiripentol and carisbamate. Most of the literature related to these AEDs was published in the past 5 years.
What the reader will gain: The reader will become familiar with the pharmacology of emerging AEDs and the results of clinical trials with these AEDs. The reader will also be able to assess the advantages of AEDs and their potential respective places in the treatment of epilepsy.
Take home message: The emerging AEDs offer predominantly improved pharmacokinetics and tolerability and occasionally new mechanisms of action. They will probably have a modest impact on drug-resistant epilepsy.
