Lacosamide is a prescription medication that is primarily used in the treatment of epilepsy. It is sold under the brand name Vimpat. Lacosamide is classified as an antiepileptic drug (AED) and is specifically approved for the management of partial-onset seizures in adults and children aged four years and older. The exact mechanism of action of lacosamide is not fully understood. However, it is believed to work by selectively enhancing the slow inactivation of sodium channels in the brain. By doing so, it helps stabilize overactive electrical activity in the brain that can lead to seizures. .
