As manufacturer of Oxcarbazepine we hereby state the following facts about the drug:

Oxcarbazepine is an anticonvulsant. It works by decreasing nerve impulses that cause seizures and pain.

Oxcarbazepine is used either alone or with other medicines to treat partial seizures.

Oxcarbazepine is a dibenzazepine carboxamide derivative with an anticonvulsant property. As a prodrug, oxcarbazepine is converted to its active metabolite, 10-monohydroxy. Although the mechanism of action has not been fully elucidated, electrophysiological studies indicate this agent blocks voltage-gated sodium channels, thereby stabilizing hyper-excited neural membranes, inhibiting repetitive neuronal firing, and decreasing the propagation of synaptic impulses.

Drug Indication

In the United States, oxcarbazepine is indicated as monotherapy in the treatment of partial-onset seizures in patients 4 years of age and older, and as adjunctive therapy in the treatment of partial-onset seizures in patients 2 years of age and older. In Canada, oxcarbazepine is indicated for use as monotherapy or adjunctive therapy in the treatment of partial-onset seizures in patients 6 years of age and older.

Mechanism of action

The exact mechanism through which oxcarbazepine and its active metaoblite, MHD, exert their anti-epileptic effects is unclear, but is thought to primarily involve the blockade of voltage-gated sodium channels. The opening and closing of sodium channels allows for the propagation of action potentials along neurons – in epilepsy, these action potentials can occur in excess of that required for normal function, and the repetitive and pathological firing of these action potentials leads to seizure activity.
