In an age where medicine is evolving faster than ever, pharmacogenomics stands at the frontier of a new era-personalized healthcare. This groundbreaking book takes you into the world where genes meet drugs, revealing how your DNA can influence the way medications work for you.From the basics of genetics to the complexities of gene-drug interactions, Pharmacogenomics presents a clear, in-depth look at how genetic variation impacts drug metabolism, efficacy, and safety. With real-world clinical examples-from cancer therapies and cardiovascular drugs to psychiatric treatments-the book illustrates how pharmacogenomic testing can guide more effective, safer prescriptions tailored to each individual.Explore key genetic players like the CYP450 enzymes, ABCB1 transporter, and critical variants such as HLA-B and VKORC1. Learn how modern genotyping technologies and bioinformatics tools are reshaping drug discovery, clinical trials, and therapeutic strategies. This book also addresses the ethical, legal, and social challenges of using genetic data in medicine, advocating for privacy, equity, and informed consent.
