Abstract:
This research aims to explore the role of pharmacogenomics in optimizing drug therapy for individual patients. Pharmacogenomics is a field that investigates how an individual’s genetic makeup influences their response to medications. By understanding the genetic variations that affect drug metabolism, efficacy, and safety, personalized medicine can be tailored to maximize therapeutic outcomes while minimizing adverse effects. This comprehensive review will examine the current state of knowledge in pharmacogenomics, its applications in optimizing drug therapy, challenges, and future directions. The findings of this research will contribute to the advancement of personalized medicine and improve patient care in the treatment of various chronic diseases.
