<p>The pharmacological activity of Oxcarbazepine is primarily exerted through the metabolite derivative (the monohydroxy derivative, MHD) of Oxcarbazepine. The mechanism of action of Oxcarbazepine and MHD is thought to be mainly based on blockade of voltage-sensitive sodium channels, thus resulting in stabilization of hyper excited neural membranes, inhibition of repetitive neuronal firing and diminishment of propagation of synaptic impulses.</p>
