The half-life of oxcarbazepine is only 1 to 2.5 hours, but the half-life of its active metabolite, 10-hydroxycarbazepine, is 11 to 15 hours. Therefore, plasma levels of the active metabolite, 10-hydroxycarbazepine, are used to guide treatment. For the management of seizures, plasma levels of the active metabolite of oxcarbazepine, 10-hydroxycarbazepine, should be between 15 and…
