Eslicarbazepine acetate (brand names Aptiom, Zebinix, Exalief), abbreviated as ESL, is an anticonvulsant approved for use in Europe and the United States as an adjunctive therapy for epilepsy.[citation needed]

Similarly to oxcarbazepine, ESL behaves as a prodrug to eslicarbazepine ((S)-(+)-licarbazepine).[1] As such, their mechanisms of action are identical.[2] However, there may be pharmacokinetic differences between the two drugs; for instance, ESL may not produce as high of peak levels of (S)-(+)-licarbazepine immediately after dosing as does oxcarbazepine, which could, in theory, improve tolerability.[citation needed]

Like oxcarbazepine, ESL may be used to treat bipolar disorder and trigeminal neuralgia.
