Background: Therapeutic drug monitoring (TDM) of antiseizure medications (ASMs) is widely used to guide therapy, avoid toxicity, and assess patient compliance. Commercial immunologic quantification methods are common practice; however, as they are only applicable to one specific drug and prone to cross-reacting metabolites, their practical applicability is limited. In this article, the authors proposed a high-performance liquid chromatography method using ultraviolet detection (HPLC-UV) for simultaneous quantification of 11 ASMs and active metabolites (carbamazepine, felbamate, lacosamide, lamotrigine, levetiracetam, phenobarbital, phenytoin, primidone, zonisamide, carbamazepine-10,11-epoxide, and licarbazepine) in serum.
