How Does Depakote ER Work?
Depakote ER works by increasing the amount of gamma-aminobutyric acid (GABA) in the brain. GABA is a natural chemical that stops or slows down other brain signals. Increasing GABA helps prevent the abnormal brain signals that lead to a seizure. It is also thought that Depakote ER may prevent seizures by affecting sodium channels in the brain.
