OXCARBAZEPINE
OXCARBAZEPINE is indicated for the treatment of Partial-onset seizures in adults (monotherapy); Partial-onset seizures in adults (adjunctive therapy); Partial-onset seizures in pediatric patients aged 4 to 16 years (monotherapy); Partial-onset seizures in pediatric patients aged 2 to 16 years (adjunctive therapy).
How OXCARBAZEPINE Works
Oxcarbazepine exerts its anti-seizure effects primarily through its 10-monohydroxy metabolite (MHD), which blocks voltage-sensitive sodium channels. This blockade stabilizes hyperexcited neural membranes and inhibits repetitive neuronal firing, which diminishes the propagation of synaptic impulses. These actions work together to prevent the spread of seizures within the brain. The drug may also contribute to anticonvulsant activity by increasing potassium conductance and modulating high-voltage activated calcium channels.
