CYP450 inhibitor

A CYP450 inhibitor is a substance that blocks or reduces the activity of certain liver enzymes called cytochrome P450 enzymes. These enzymes are responsible for breaking down many medications in the body. When an inhibitor is present, it can slow this process, leading to higher levels of the medication circulating in the bloodstream. This can increase the risk of side effects or toxicity. Understanding CYP450 inhibitors helps doctors manage drug interactions and ensure medications are used safely and effectively.
