Pharmacogenomics is the study of how an individual's genetic makeup affects their response to drugs. This field aims to personalize medication therapy, enabling more effective treatment plans based on genetic variations. Pharmacogenomics can identify which medications work best for specific genetic profiles, significantly reducing adverse drug reactions and improving therapeutic outcomes. By tailoring treatments, healthcare providers can enhance patient care and move towards the more individualized approach termed precision medicine, contributing to developments in pharmacology and genetic research.
