How does Perampanel work?
Perampanel is a non-competitive AMPA glutamate receptor antagonist. It’s thought to block glutamate from attaching to its receptors in the brain. Glutamate is a chemical in the brain that causes a lot of brain activity and plays a role in seizures. By stopping the actions of glutamate in the brain, Perampanel causes nerve cells to become less active, which helps prevent seizures.
