Abstract

Pharmacogenomics, the study of how genes influence an individual’s response to drugs, is revolutionizing the field of personalized medicine. By tailoring drug therapy based on genetic profiles, pharmacogenomics promises to optimize drug efficacy, minimize adverse effects, and improve patient outcomes. This article reviews the current state of pharmacogenomics, its impact on drug development, and its clinical applications in personalized medicine. Key areas of focus include genetic variations in drug metabolism, drug receptors, and the implications for drug therapy in different populations. We also discuss the challenges in implementing pharmacogenomic-based therapies and the future prospects for integrating pharmacogenomics into clinical practice.
