Therapeutic drug monitoring of vancomycin in surgical patients using a validated HPLC method.

This study focuses on therapeutic drug monitoring of vancomycin in surgical patients using a validated hplc method.. The research employs high-performance liquid chromatography (HPLC) techniques to address analytical challenges in the clinical field. Vancomycin is being used for the treatment of a variety of infections caused by methicillin resistant... Research Background and Significance Vancomycin is a glycopeptide antibiotic widely employed in the treatment of severe infections caused by methicillin-resistant Staphylococcus aureus (MRSA) and other resistant Gram-positive bacteria. Its narrow therapeutic index and considerable interpatient pharmacokinetic variability necessitate precise therapeutic drug monitoring (TDM) to optimize dosing, minimize toxicity, and improve clinical outcomes, particularly in vulnerable populations such as surgical patients. The complexity of vancomycin pharmacokinetics in critically ill surgical patients, who often exhibit altered drug clearance due to physiological changes, underscores the need for reliable and validated analytical techniques. High-performance liquid chromatography (HPLC) remains a gold standard for quantifying vancomycin concentrations in biological matrices, offering high specificity, sensitivity, and reproducibility. This study by Akram et al. (2024) addresses the critical requirement for a validated HPLC method tailored to surgical patients, ensuring dependable TDM to guide clinical decision-making and improve therapeutic efficacy. Experimental Design and Methodology The study employed a validated reversed-phase HPLC method to quantify vancomycin concentrations in plasma samples collected from surgical patients undergoing treatment. The chromatographic separation was optimized using a C18 stationary phase, which is
