TODAY. 1  Doctors are increasingly aware that genetic variationscan cause different patients to respond in different ways to the same medication. The study of how genes affect the way a person responds to medicines is called pharmacogenetics or pharmacogenomics. Advances in understanding the genetic basis of individual drug responses come from the NIH Pharmacogenomics Research Network (PGRN) (http://www.nigms.nih.gov/Initiatives/PGRN).
A drug-nutrient interaction is the effect of a medication on food or a nutrient in food. Medications interact with foods and nutrients in several ways. Medications can decrease ap-petite or change the way a nutrient is absorbed, metabolized, or excreted. A food-drug interaction is the effect of food or a nutrient in food on a medication. Dietary nutrients can affect medications by altering their absorption or metabolism. The food you eat could make the medications you take work faster, slower, or even prevent them from working at all.
