Sodium Valproate + Valproic acid Pharmacology
Sodium Valproate + Valproic acid
Sodium Valproate
Valproic acid enhances the release and synthesis of inhibitory neurotransmitter GABA and inhibits its degradation. This will result in an increased concentration of GABA and is used as antiepileptic agent. Valproate is also used to treat the acute manic phase of bipolar disorder and for the prophylaxis of migraine.
