Cytochrome P450 (CYP450) tests help determine how your body processes (metabolizes) or responds to medications. We look for variations in cytochrome P450 genes that can affect the breakdown of medications. Depending on the gene and the polymorphism, drugs can be metabolized quickly or slowly. If a cytochrome P450 enzyme metabolizes a drug slowly, the drug stays active longer in the body and therefore less is needed to get the desired effect. Alternatively, if a drug is quickly metabolized it is broken down sooner and a higher dose might be needed to be effective.
Drug metabolism of cytochrome P450 (CYP450) also plays important part in several drug interactions that can result in drug toxicities, reduced pharmacological effect, and adverse drug reactions. Call us Today with any questions you might have at 972-668-6005.
