Active ingredients in N03AF

Active Ingredient

Carbamazepine is a derivative of dibenzazepine. It belongs to the pharmaceutical class of antiepileptic, neurotropic and psychotropic drugs. Carbamazepine helps control the transmission of messages from the brain to the muscles.

Eslicarbazepine and its metabolites stabilise the inactivated state of voltage-gated sodium channels, precluding their return to the activated state and thereby preventing repetitive neuronal firing. Therefore eslicarbazepine is indicated as adjunctive therapy in adults with partial-onset seizures with or without secondary generalisation.

The pharmacological activity of oxcarbazepine is primarily exerted through the metabolite (MHD). The mechanism of action of oxcarbazepine and MHD is thought to be mainly based on the blockade of voltage-sensitive sodium channels.

Rufinamide is an anticonvulsant medication. Rufinamide modulates the activity of sodium channels, prolonging their inactive state.
