Valproate is a generic term used to describe valproic acid, its salts and derivatives. It is available in various forms including the sodium salts (valproate semisodium and sodium valproate), the amide derivative (valpromide), or as valproic acid. Valproate is a carboxylic acid anticonvulsant. It has been suggested that its antiepileptic activity is related to increased brain levels of γ-aminobutyric acid (GABA).
