WebJan 1, 2024 · Induction of cytochrome P450 (P450) can impact the efficacy and safety of drug molecules upon multiple dosing with coadministered drugs. This strategy is focused on CYP3A since the majority of clinically relevant cases of P450 induction are related to these enzymes. However, the in vitro evaluation of induction is applicable to other P450 … WebCytochrome P450 (CYP450) are a group of enzymes encoded by the P450 genes and responsible for the metabolism of most drugs seen in clinical practice. 90% of drugs are metabolised by CYP3A5, CYP3A4, CYP2D6, …
WebAccumulating evidence has revealed that CYP3A4 and CYP3A5 have a significant overlapping in their substrate specificity, inducers and inhibitors. Therefore, it is difficult to define their respective contribution to drug metabolism and drug-drug interactions.
