How does Potiga work to treat seizures?

Doctors aren't sure exactly how Potiga (ezogabine) works to treat seizures. When used in combination with other medications, Potiga reduces the frequency of partial seizures (also called "focal seizures") in the brain, which are the most common type of seizure experienced by people who have epilepsy.

Unlike general seizures, which occur in both parts of the brain, partial seizures happen in just one side of the brain. Seizures are believed to be caused when neurons (nerve cells) in the brain fire faster than normal, leading to symptoms that may include strange sensations, emotions and behaviors, and involuntary movements, spasms and convulsions. Potiga is thought to help reduce the "excitability" of the brain's electrical system, making seizures less likely to occur.
