Chemical Structure

Biological activities

Oxcarbazepine is an anticonvulsant and mood stabilizing drug. Oxcarbazepine is used primarily in the treatment of not only epilepsy but also anxiety and mood disorders. Oxcarbazepine blocks the frequency of firing of sodium-dependent action potentials by cultured mouse central neurons with IC50 of 50 nM.[1] Oxcarbazepine reduces L-type calcium currents by about 30% at the concentration of 0.3 mM. [2] Oxcarbazepine generates a marked concentration- and frequency-dependent reduction in the compound action potential amplitude.[3] Oxcarbazepine (0.3-30 µM) induces a reversible reduction in the amplitude of voltage-gated Na+ current (INa) with an IC50 of 3.1 µM.[4] Oxcarbazepine treats generalized tonic-clonic seizures induced by electroshock in mice and rats with ED50 values ranging from 13.5 to 20.5 mg/kg p.o. Oxcarbazepine does not produce tolerance toward this anticonvulsant effect in the process of 4-week treatment. [2] Intravenous administration of oxcarbazepine (1-10 mg/kg) inhibits the P3 component in a dose-dependent manner.[5]

Protocols

Oxcarbazepine is dissolved in PEG400 in vivo assay.[5]
