Accumulating evidence has revealed that CYP3A4 and CYP3A5 have a significant overlapping in their substrate specificity, inducers and inhibitors. CYP450 inhibitors increase the concentration of drugs metabolised by the CYP450 system. A selected list of such interactions appears in the Table. The following sentence may contain a comma error. For example, CYP2D6 polymorphisms are expressed in four different phenotypes: Poor metabolisers are characterised by the inability to metabolise drugs via the CYP2D6 metabolic pathway, resulting in an increased risk of adverse effects and toxicity. - 700+ OSCE Stations: https://geekymedics.com/osce-stations/ Enzyme substrates are drugs or other substances that bind to and are metabolised by the CYP450 enzymes.
