As monotherapy or adjunctive therapy in the treatment of partial seizure in adults and child with epilepsy
藥理
Oxcarbazepine and its active metabolite (10-monohydroxy derivative, MHD) is thought to be mainly based on blockade of voltage-sensitive sodium channels, thus resulting in stabilization of hyper excited neural membranes, inhibition of repetitive neuronal firing, and diminishment of propagation of synaptic impulses.
藥動學
Oxcarbazepine is completely absorbed; food has no effect on rate or extent. It is converted into active metabolite (MHD) in liver; about 40% of MHD is bound to serum proteins, mainly albumin. MHD is eliminated primarily by glucuronidation to inactive products (47%) and renal excretion of unchanged MHD (27%). Elimination half-life: oxcarbazepine 2.4±1.1 hr; MHD: 9.3±1.8 hr; renal impairment (Clcr <30 ml/min): MHD: 19 hr.
禁忌症
Hypersensitivity to the active substance or to any of the excipients.
