Description

It is a broad spectrum anticonvulsant
Mechanism of Action
Valproate appears to act by multiple mechanisms:

(a) A Phenytoin like frequency dependent prolongation of Na+ channel inactivation
(b) Attenuation of Ca2+ mediated ‘T’ current
(c) Augmentation of release of inhibitory transmitter GABA by inhibiting its degradation as well as increasing its synthesis.

Oral absorption of Valproic acid is good. Peak plasma levels are achieved in 1-4 hrs. It is 90% bound to plasma proteins; 95% metabolized in liver by oxidation and glucuronide conjugation – excreted in urine. Plasma t½ is 15 hours; but anticonvulsant effects are longer lasting
