Antiepileptic drugs--a review.

Epilepsy is a common neurological condition that affects approximately 1% of the general population. In addition, about 10% of the population experiences a seizure sometime during life. The treatment options for epilepsy have come a long way from the bromides to the current era in which we now have multiple treatment modalities, including medications, implantable devices, and surgery. Antiepileptic drugs (AEDs) are the mainstay for treatment of epilepsy with about 70% of children achieving good control with medications alone. The past decade has witnessed the emergence of multiple AEDs-with more than 24 AEDs to choose from presently. The newer drugs provide us with novel mechanisms of action and improved safety profile. This expanded choice of AEDs has made it possible to offer tailored-treatment plans based on unique patient profiles. However, such an ever-increasing choice of medications also poses a challenge for the treating physician as far as choosing the initial drug is concerned-especially because there is limited data comparing the efficacy of one drug to the other. An additional humbling fact remains that, despite an increase in the choice of medications, we are still only able to treat the symptoms of seizures without making any significant progress in reversing or stopping the underlying mechanism of epileptogenesis or in offering neuroprotection from epileptogenesis. Therefore, it is not surprising that, despite the wide array of AED choices, the prevalence of drug-resistant epilepsy has not improved. This article aims at giving a short overview of currently available AEDs. Copyright 2015, SLACK Incorporated.
