Abstract

Clinicians should be cognizant of potential drug drug interactions and become familiar with the substrates, inhibitors and inducers of the common enzymatic pathways responsible for drug metabolism. Our knowledge of and ability to predict drug interactions have improved with growing understanding of substrates, inhibitors and inducers of cytochrome P450 (CYP-450) isoenzymes. These isoenzymes are a major determinant of the pharmacokinetic behavior of numerous drugs. In addition to inhibition and induction, microsomal drug metabolism is affected by genetic polymorphisms, age, nutrition, hepatic disease and endogenous chemicals. Prescribing physicians by understanding the unique characteristics of these isoenymes may better anticipate and manage drug drug interactions.


Keywords: Cytochrome P450, drug interaction, enzyme inhibitor
