Emerging Trends In Bioanalytical Methods For Drug Metabolism Studies

Abstract

Bioanalytical methods play a crucial role in understanding drug metabolism, pharmacokinetics, and bioavailability. Recent advancements in liquid chromatography-tandem mass spectrometry (LC-MS/MS), capillary electrophoresis, and high-resolution mass spectrometry have enhanced the precision and reliability of drug quantification in biological matrices. This paper provides an overview of current bioanalytical techniques employed for the evaluation of drug absorption, distribution, metabolism, and excretion (ADME) characteristics. It also discusses sample preparation methods such as solid-phase extraction and protein precipitation, which are critical in minimizing matrix effects. Emphasis is placed on method validation parameters, regulatory frameworks, and automation trends in bioanalytical laboratories. The integration of metabolomics and proteomics further extends the applicability of bioanalytical approaches to personalized medicine and pharmacogenomics.
