CYP450 refers to a family of enzymes that play a critical role in the metabolism of many drugs within the body. Specifically, these enzymes are responsible for the oxidative metabolism of various substances, which includes both endogenous compounds, such as hormones, and exogenous compounds, like medications. The CYP450 system is essential for the biotransformation of drugs, influencing their pharmacokinetics, efficacy, and safety.

These enzymes are located primarily in the liver and are involved in the process of converting lipophilic chemical compounds into more hydrophilic metabolites that can be excreted from the body. Due to the significant impact that CYP450 enzymes have on drug metabolism, variations in their activity among individuals can lead to differences in drug responses, therapeutic outcomes, and the likelihood of adverse effects. Understanding the role of CYP450 is crucial for healthcare professionals when considering drug interactions and personalized medicine.
