Abstract
Carbamazepine, and the newer but structurally related oxcabazepine and eslicarbazepine acetate, belongs to the dibenzazepine group of antiepileptic drugs, mainly used for patients with focal epilepsy. Like other antiepileptic substances, their mechanism of action is thought to be the inhibition of the voltage-gated sodium channel. Little differences can be found in efficacy among these three drugs. Despite showing similar dose-dependent adverse effect profile, there are important differences regarding pharmacokinetics and toxicity. For instance, carbamazepine is a stronger cytochrome inducer and oxcarbazepine causes more often hyponatremia. Although data on teratogenicity is sparse with eslicarbazepine acetate, the other two dibenzazepines seem to be minor teratogens. Because of their efficacy in focal epilepsy, and other epileptic syndromes, as well as some psychiatric and pain conditions, they are one of the most prescribed families of antiepileptic drugs.
