Therapeutic drug monitoring of lacosamide among children: is it helpful?

This study focuses on therapeutic drug monitoring of lacosamide among children: is it helpful?. The research employs high-performance liquid chromatography (HPLC) techniques to address analytical challenges in the clinical field. Research Background and Significance Therapeutic drug monitoring (TDM) plays a crucial role in optimizing pharmacotherapy, particularly in pediatric populations where drug metabolism and pharmacokinetics can significantly vary. Lacosamide, an antiepileptic drug commonly prescribed to children with refractory seizures, requires careful dose adjustments to maximize efficacy while minimizing adverse effects. However, clinical application of TDM for lacosamide has been limited by analytical challenges, including the need for sensitive, precise, and reliable quantification methods. This study addresses this gap by employing high-performance liquid chromatography (HPLC) techniques to develop and validate a robust assay for lacosamide quantification in pediatric samples. The significance lies in improving clinical decision-making through reliable TDM, potentially enhancing therapeutic outcomes and safety in children. Experimental Design and Methodology The study utilized HPLC as the primary analytical tool to establish a validated method for lacosamide quantification in biological matrices. While specific instrumentation details are not provided, the methodology focused on reversed-phase chromatography, likely employing C18 stationary phases due to their widespread use in clinical drug analysis. Sample preparation involved standard clinical protocols to extract lacosamide from patient samples, ensuring removal of interfering substances to improve assay specificity. The chromatographic conditions were optimized to achieve adequate retention and resolut
