DEPAKOTE (divalproex sodium) · AbbVie

CNS Approved 1983-03-10

Depakote is an anti-epileptic drug indicated for the treatment of manic episodes associated with bipolar disorder and the prophylaxis of migraine headaches. It is also approved as monotherapy and adjunctive therapy for patients with complex partial seizures and simple or complex absence seizures. Furthermore, the medication is indicated as an adjunctive treatment for patients with multiple seizure types that include absence seizures.

How DEPAKOTE Works

Divalproex sodium is a valproate compound that dissociates into the valproate ion within the gastrointestinal tract. While the exact mechanisms for its therapeutic effects have not been established, its activity in treating epilepsy is suggested to be related to its impact on brain chemistry. Specifically, the drug is believed to work by increasing the concentrations of gamma-aminobutyric acid (GABA) in the brain.
