Ingredient-level reference
Sodium valproate (oral reference)
Reference for: Sodium Valproate. Source presentation: GASTRO-RESISTANT TABLET. Source route: oral.
The cited studies use delayed-release gastro-resistant tablet. The catalogue entry has a different or unspecified release description; these study values do not establish its absorption profile.
Mechanism of action
The reference describes enhancement of inhibitory GABA activity, through effects on its synthesis or metabolism, as a likely anticonvulsant mechanism rather than a fully established single pathway.
Pharmacokinetics
The gastro-resistant-tablet reference reports a usual unbound plasma fraction of about 6–15%. Glucuronidation is a major metabolic pathway, and reported half-life is generally 8–20 hours, with substantial age-related variation. Total plasma concentrations do not always track unbound drug or clinical effect. These findings do not establish modified-release or injectable exposure. The full label includes major reproductive-risk restrictions.
