Generic Trileptal

Common use

Oxcarbazepine is an antiepileptic drug used to treat seizure disorders (epilepsy). The exact mechanism of action of Oxcarbazepine and its active metabolite 10-monohydroxy metabolite (MHD) are unknown. Oxcarbazepine blocks potential-dependent sodium channels resulting in stabilization of overexcited neurons membranes, inhibition of a series of discharges in neurons and reduction of synaptic impulses. Increased K+ conductance and modulation of Ca2+ channels activated by a high potential of the membrane also invest in the antiepileptic effect of the drug. Oxcarbazepine may rarely be used for treatment of bipolar disorder (manic-depressive disorder).



Dosage and direction

Oxcarbazepine is sold as a tablet and a suspension (liquid) to take orally. The medication is usually taken every 12 hours with or without food. Take Oxcarbazepine the same times every day to keep the level of medication in your blood constant. Shake the suspension thoroughly before each use to make the mixture even. Do not suddenly stop taking this drug without your doctor's approval as seizures may become worse.
