about sodium valproate -histone deacetylase inhibitor gaba agent anticonvulsant antimanic migraine prophylaxis. -mechanism of action of sodium valproate -sodium valproate is the sodium salt of valproic acid.after oral administration it is quiickly converted to valproic acid.valproic acid prolongs the inactivated state of voltage sensitive neuronal sodium ion channel either by increasing the efflux or by decreasing the influx of sodium ion across the cell membrane and inhibits the high frequency neuronal discharge. it blocks the propagation of neuronal impulses. it also modulates neurotransmitter release and neuronal bursting through an effect on voltage gated and receptor gated calcium channels. -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. -about valproic acid -histone deacetylase inhibitor a gaba transaminase inhibitor
