PHARMACOGENOMICS: TAILORING DRUG THERAPY BASED ON GENETIC INFORMATION

Pharmacogenomics, the study of how genes affect a person’s response to drugs, is an emerging field in personalized medicine that aims to tailor drug therapies based on genetic information. This field holds the potential to improve drug efficacy, minimize adverse drug reactions (ADRs), and reduce healthcare costs. By understanding an individual’s genetic makeup, pharmacogenomics can help predict how patients will respond to specific medications, leading to more effective and safer treatments. This article explores the principles of pharmacogenomics, its clinical applications, the role of genetic variants in drug metabolism, and the challenges faced in implementing pharmacogenomics in routine clinical practice. Special focus is given to the pharmacogenomic landscape in Pakistan and its future potential in improving healthcare outcomes. The article concludes with a discussion on the ethical, social, and logistical challenges of incorporating pharmacogenomics into healthcare systems worldwidey.
