New treatment option for partial-onset seizures: efficacy and safety of lacosamide

Abstract

More than 30% of epilepsy patients remain refractory despite the advent of new antiepileptic drugs (AEDs) over two decades. Although a small percentage of these refractory patients may become seizure free when a new AED is added, combined administration of AEDs or the application of novel AEDs is the most common therapeutic option when surgical treatment cannot be offered. The most recently approved AED in Europe and the USA is lacosamide (LCM), which offers new mechanisms of action and favorable safety profiles. This article reviews LCM’s molecular mechanisms of action, pharmacokinetic profiles as well as efficacy and safety from phase II and III clinical trials. In addition, comparison between LCM and other existing AEDs is discussed.
