Description

Valproic acid and its derivative, divalproex, are oral drugs that are used for the treatment of convulsions, migraines and bipolar disorder. The active ingredient in both products is valproic acid. Divalproex is converted to valproic acid in the stomach. The most popular theory is that valproic acid exerts its effects by increasing the concentration of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter, a chemical that nerves use to communicate with one another.
