Headline: Personalized Medicine Arrives: Pharmacogenomics Transforming Drug Prescriptions in India and Beyond
New Delhi, November 21, 2025 – The traditional “one-size-fits-all” approach to medication is rapidly becoming obsolete as pharmacogenomics, the study of how genes influence drug response, revolutionizes healthcare. Today’s edition of The Hindu highlights the growing adoption of pharmacogenomics, paving the way for personalized drug therapy.
The article details how genetic variations can significantly affect an individual’s reaction to medication, determining whether a drug will be effective, ineffective, or even dangerous. This variability largely stems from differences in drug-metabolizing enzymes like the cytochrome P450 (CYP) family, which processes about 75% of commonly prescribed drugs. It means that standard doses can potentially have dangerous consequences. Studies show that approximately 90% of people carry at least one actionable pharmacogenetic variant.
According to the article, pharmacogenomics has already delivered measurable gains in areas like cardiovascular medicine, psychiatry, and oncology. Examples include using genetic markers to optimize Warfarin dosage, choosing alternative antiplatelet agents for patients with CYP2C19 variants, and preventing life-threatening toxicity with certain chemotherapy drugs.
The economic benefits of genetic-guided prescription is cost effective for several drug-gene pairs, particularly in chronic disease where patients require long-term medication management, by reducing adverse drug reactions. While upfront testing costs have fallen dramatically, challenges remain in the form of healthcare provider education, infrastructure limitations in electronic health record systems, and reimbursement uncertainty.
Despite these challenges, experts predict a future where pre-emptive genetic testing becomes a routine component of preventive medicine. The goal: a fundamental shift towards treating individuals rather than populations, ultimately leading to safer, more effective, and more efficient healthcare.
