Pharmacogenomics is the study of how an individual's genetic makeup affects their response to drugs. This field combines pharmacology and genomics to develop effective, safe medications tailored to each person's genetic profile. By understanding genetic variations, healthcare providers can predict how patients will respond to specific treatments, minimizing adverse effects and improving therapeutic outcomes. As a result, pharmacogenomics plays a crucial role in personalized medicine, allowing for more precise prescribing practices. This approach not only enhances patient care but also contributes to the development of new drugs that are more effective for specific genetic groups, paving the way for advancements in medical science.
