Mechanism of Action of Oxcarbazepine
Oxcarbazepine 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 discharge.
It blocks the repetitive impulses that trigger seizures and it stabilizes the neuronal membrane. In addition it increases the potassium conductance and modulates the high voltage activated calcium channels. These also produce anticonvulsant effect.
