Q

Know how CYP450 can affect drug metabolism and what foods clients should avoid.

A

CYP enzymes are liver enzymes that metabolize drugs and other endogenous substances. The majority of these enzymes inactivate drugs and accelerate their excretion
- Enzyme inhibitors (Grapefruit juice) cause an increase in the amount of active medication entering the bloodstream
- Enzyme induction results in a decreased amount of active medication reaching the bloodstream
