Sodium Valproate Gastro-Resistant Tablets are prescription medicines primarily used to treat various types of epilepsy (seizure disorders). They belong to a class of medications known as antiepileptic drugs (AEDs) or anticonvulsants. The gastro-resistant (enteric-coated) formulation helps the tablet pass through the stomach and dissolve in the intestine, reducing stomach irritation and improving tolerability.
