Adjunctive treatment of partial-onset seizures in adults with epilepsy who are not adequately controlled with other antiepileptic medications.

Ezogabine activates voltage-gated potassium channels (specifically KCNQ2-5 channels), which helps stabilize neuronal membranes and reduces the repetitive firing of neurons that leads to seizure activity.

May cause urinary retention, QT prolongation, and neurological effects such as dizziness and somnolence. Has been associated with blue skin discoloration with prolonged use. Should be used with caution in patients with a history of urinary retention or cardiac conduction abnormalities.
