In particular, CYP2D6 is responsible for the metabolism and elimination of approximately 25% of clinically used drugs, via the addition or removal of certain functional groups – specifically, hydroxylation, demethylation, and dealkylation. CYP2D6 also activates some prodrugs. See more Cytochrome P450 2D6 (CYP2D6) is an enzyme that in humans is encoded by the CYP2D6 gene. CYP2D6 is primarily expressed in the liver. It is also highly expressed in areas of the central nervous system, … See more The gene is located on chromosome 22q13.1. near two cytochrome P450 pseudogenes (CYP2D7P and CYP2D8P). Among them, CYP2D7P originated from CYP2D6 in a stem lineage of great apes and humans, the CYP2D8P originated from CYP2D6 in a … See more Ethnicity is a factor in the occurrence of CYP2D6 variability. The lack of the liver cytochrome CYP2D6 enzyme occurs approximately in 7–10% in white populations, and is … See more • Smith G, Stubbins MJ, Harries LW, Wolf CR (December 1998). "Molecular genetics of the human cytochrome P450 monooxygenase … See more CYP2D6 shows the largest phenotypical variability among the CYPs, largely due to genetic polymorphism. The genotype accounts for … See more The genetic basis for CYP2D6-mediated metabolic variability is the CYP2D6 allele, located on chromosome 22. Subjects possessing certain allelic variants will show normal, decreased, or no CYP2D6 function, depending on the allele. Pharmacogenomic … See more Following is a table of selected substrates, inducers and inhibitors of CYP2D6. Where classes of agents are listed, there may be exceptions within … See more WebThe CYP2D6 enzyme metabolizes fewer drugs and therefore is associated with an intermediate risk of drug-drug interactions. Drugs that undergo phase 2 conjugation, and therefore have little or no involvement with the CYP system, have minimal interaction potential. Phase1 Metabolism

WebCYP2D6 activity may be impaired by inhibitors such as paroxetine and fluoxetine. Inhibition of CYP2D6 activity may result in nonlinear plasma drug concentration kinetics, as well as kinetic drug interactions when other drugs metabolized by CYP2D6 are coadministered.
