Many drug interactions are a result of inhibition or induction of cytochrome P450 enzymes (CYP450). As a consequence, these drugs can increase the concentrations of co-administered metabolized drugs, and are subject to having their own concentrations increased by other CYP inhibitors. SUMMARY Cytochrome enzyme inhibition can occur by several mechanisms. Would you like email updates of new search results?

Note: CYP3A4 is the main enzyme that metabolizes Gleevec and therefore effects may be more pronounced that those related to CYP2D6.
