Pharmacogenomics uses genetic screening to maximize drug choice, dose, and response, minimizing adverse reactions and enhancing results. It is especially applicable in internal medicine for the treatment of cardiovascular illness, mental health diseases, and oncology, where drug metabolism is highly variable across individuals.
Internists employ pharmacogenomic information to inform safe prescribing, prevent ineffective treatment, and tailor treatment regimens. Pharmacogenomics is increasingly becoming a valuable tool for precision medicine as gene-based medicine is developed further, allowing doctors to provide extremely individualized care.
