Drugs are metabolized by the body in much the same way as food, herbals, and environmental pollutants; they are broken down by liver and gut enzymes or other mechanisms so they can be absorbed and eliminated in the bile and urine. Enzymes are available to metabolize specific substancesa medication is referred to as a substrate of the enzyme that can metabolize it.



What drugs does testing apply to? When is testing indicated? How much does testing cost? What are your laboratory qualifications? These variations in response and side effects are caused by many variables, but genetic variation and metabolismbased drug, herbal, and food interactions are among the most common.

Often an enzyme will be capable of breaking down more than one substance, but sometimes if two or more drugs that use the same enzyme are taken (and metabolized) at the same time, an interaction can occur. Enzymerelated drug interactions can be brought about because some drugs, called inducers, increase the activity of an enzyme and others, called inhibitors, reduce it. Additionally, genetics can determine your inborn ability to create many of the enzymes in the liver or gut, and the amount of an enzyme that is available can dramatically alter how you process medication. In addition, to being ineffective, sometimes medications can be dangerous. These reactions are most common in patients taking multiple medications.
