Oxcarbazepine

Oxcarbazepine is a keto analogue of carbamazepine and, like the parent drug, is a potent anticonvulsant used alone or in combination with other agents in the therapy of poartial seizures. 

Liver safety of Oxcarbazepine

Oxcarbazepine has been linked to rare instances of clinically apparent acute drug induced liver injury which resembles carbamazepine hepatotoxicity.

Mechanism of action of Oxcarbazepine

Oxcarbazepine (ox" kar baz' e peen) is a keto analog of carbamazepine and functions as a prodrug being rapidly converted to 10-hydroxycarbazepine.  Oxcarbazepine and carbamazepine are iminostilbenes related chemically to the tricyclic antidepresants and unrelated in structure to most other anticonvulsants.  They appear to act by suppression of spread of seizure activity by reduction in the posttetanic potentiation of synaptic transmission.
