Mechanism of Action

The First Novel Mechanism of Action in Almost 10 Years

Vimpat works differently by selectively enhancing slow inactivation of the sodium channels.1

Selective enhancement of slow inactivation with Vimpat1:

  • Enhances the number of sodium channels entering into the slow inactivated state
  • Targets activity occurring during sustained high-frequency neuronal firing or prolonged depolarization, as seen in epilepsy
  • Regulates and reduces the long-term availability of sodium channels
  • Does not affect activity mediated by fast inactivation

The precise mechanism by which lacosamide exerts its antiepileptic effect in humans remains to be fully elucidated.
