Oxcarbazepine true is all except ?: (A) Metabolises itself, (B) Less chances of hyponatremia than carbazepine, (C) It is less enzyme inducer than carbamazepine, (D) Less chances of hepatotoxicity than carbamazepine
Answer is B. Ans. is 'b' i.e., Less chances of hyponatremia Oxcarbazepine It is rapidly conveed into active metabolite. Drug interactions and autoinduction of its own metabolism are less marked, because it is a weak enzyme inducer. Risk of hepatotoxicity is lower than with carbamazepine. Chances of hyponatremia are more with oxcarbazepine compared to carbamazepine. It 1.5 times less potent than carbamazepine.
