Trough concentration: 6-10 ug/mL
Peak concentration: less than 40 ug/mL
Critical value: See critical value list of current critical values
Optimal response to oxcarbazepine generally occurs when trough concentration is in the range of 6-10 ug/mL. Peak concentration should be less than 40 ug/mL.
Trough concentrations are most accurate and recommended for therapeutic drug monitoring. Preferably obtained just before the next dose.
