The CYP2D6 substrates making up the antipsychotics/dopamine antagonists include aripiprazole, clozapine, fluphenazine, haloperidol, metoclopramide, olanzapine, perphenazine, quetiapine, risperidone, and thioridazine. However, since the CYP2D6 enzyme is most involved in metoprolol metabolism, strong inhibitors of CYP2D6, such as paroxetine and fluoxetine, may trigger a drug–drug interaction (DDI) which can potentially produce metoprolol‐related toxicities due to an impaired metoprolol clearance 15-19. The evidence suggests that, unlike most other CYP450 enzymes, CYP2D6 is not very susceptible to enzyme induction.

This section shows the drugs associated with CYP2D6 resistance mutations. For example, a poor metabolizer should not be given codeine since the drug would have no effect (CYP2D6 activity is needed to activate the drug). John R. Horn, PharmD, FCCP, and Philip D. Hansten, PharmD. In one tragic case, a healthy breast-feeding newborn infant developed fatal morphine toxicity; his mother was an ultrarapid metabolizer who was taking codeine, and her milk contained toxic amounts of morphine.

For the same reason, it also would be prudent to avoid CYP2D6 inhibitors in patients taking tamoxifen. Note that ethnic differences exist in CYP2D6 activity. �i! Its substrate includes antidepressants, antipsychotics, analgesics, antitussives, β-blocking agents, antiarrhythmics, and antiemetics and thus its different drug metabolism affects the clinical outcome. Cytochrome P450 BACULOSOMES Plus Reagents are microsomes prepared from insect cells infected with recombinant baculovirus containing a human CYP450 isozyme, as well as human cytochrome P450 reductase. For drugs that are converted to active metabolites by CYP2D6, the addition of a CYP2D6 inhibitor will tend to inhibit the efficacy of the drug. The information on this website is not intended for direct diagnostic use or medical decision-making without review by a health care professional. In fact, almost 25% of all drugs are metabolized by CYP2D6, including dextromethorphan (a key ingredient in products such as Nyquil), beta-blockers, antiarrhythmics, and antidepressants. CYP2D6 is responsible for metabolizing a number of important drugs containing amine functional groups, including members of the following psychotropic classes: anticholinergics/parasympathomimetics, antidepressants and monoamine modulating drugs (for example, serotonin 5-HT 3 receptor antagonists, monoamine oxidase inhibitors (MAOIs), serotonin reuptake inhibitors (SSRIs), and tricyclic antidepressants); antipsychotics (typical and atypical); opiates; and synthetic opiate derivatives. CYP2D6 enzymes break down many commonly used medicines, including: codeine and some other pain relievers; some antidepressants and other psychiatric medicines; and beta blockers (used for heart conditions and high blood pressure). Drugs metabolized by CYP2D6 are Knowing what group you are in may help your doctor to pick the right medicine and right dose for you. hޤ�mo�0ǿ�_n�?��T!��R[UЍIU_�`���`V��w��]Y�)r.���~��"H�Q��*ĉ�l�� Note that in patients genetically deficient in CYP2D6 who are taking a CYP2D6 substrate, the addition of a CYP2D6 inhibitor will not result in any change in the plasma concentrations of the substrate. The genetics of CYP2D6 has been extensively studied, and individuals can be divided into 4 groups. This enzyme is also responsible for the metabolism of serotonin and dopamine and it also constitutes 40% of hepatic human phase I metabolism. The starting dose in this guideline refers to the recommended steady‐state dose. Over 100 CYP2D6 allelic variants have been identified (http://www.imm.ki.se/CYPalleles), with CYP2D6 enzyme activity ranging from no activity to ultra-rapid activity. nܹ�4��/���yw�a�s�߁7��wr �\�D��� �A��r�;")�c�\a���� �~��������e�`��~z�] � z��0葾�7�ҷzC��u��-}�P�o$}�T��Q���U�u���|v ����"��7@�^�. Some drugs, such as fluoxetine, paroxetine, and quinidine, are particularly potent inhibitors of CYP2D6; patients on these drugs may have almost no CYP2D6 activity. UM and PM are those most at risk for treatment failure or dose-dependent drug toxicity, respectively. Many other psychotherapeutic drugs are substrates for or inhibitors of CYP2D6, so this enzyme is of particular interest for patients on such drugs. Drug Gene Affected Subgroups+ Description of Gene-Drug Interaction; Amitriptyline : CYP2D6: ultrarapid, intermediate, or poor metabolizers: May alter systemic concentrations. The enzyme is highly genetically polymorphic. CYP2D6 polymorphisms can cause altered enzyme activity resulting in lower or higher than expected drug concentrations of donepezil. It is also highly expressed in areas of the central nervous system, including the substantia nigra. They may develop moderate-to-severe adverse effects from excessive morphine concentrations in the blood. For those drugs that are metabolized by CYP2D6 to inactive metabolites, CYP2D6 inhibitors may result in toxicity. Tamoxifen has a complex set of metabolic pathways, but CYP2D6 is primarily responsible for the production of Some drugs, such as fluoxetine, paroxetine, and quinidine, are particularly potent inhibitors of CYP2D6; patients on these drugs may have almost no CYP2D6 activity. Note that in patients genetically deficient in CYP2D6 who are taking a CYP2D6 substrate, the addition of a CYP2D6 inhibitor will not result in any cha… Patients who have little CYP2D6 activity, therefore, are likely to have little response to codeine. 13077 Ensembl ENSG00000140505 ENSMUSG00000032310 UniProt P05177 P00186 RefSeq (mRNA) NM_000761 NM_009993 RefSeq (protein) NP_000752 NP_034123 Location (UCSC) Chr 15: 74.75 – 74.76 Mb Chr 9: 57.68 – 57.68 Mb PubMed search Wikidata View/Edit Human View/Edit Mouse Cytochrome P450 1A2 (abbreviated CYP1A2), a member of the cytochrome P450 mixed-function … CYP2D6 is one of the most widely investigated CYPs.

The CYP2D6 gene is highly polymorphic. Drugs that inhibit CYP2D6 activity are likely to increase the plasma concentrations of certain medications, and, in some cases, adverse outcomes will occur (see Table 3 below right for a list of known inhibitors). CYP2D6 is one of the most important enzymes associated with detoxification. Guideline on the Investigation of Drug Interactions. Drugs metabolised by CYP2D6. Expert panelists review the causes, diagnostic work-up, management, and emerging therapies inherent in the evolving paradigm of irritable bowel syndrome. The wikipedia article on CYP2D6 is a good resource to learn about this gene, and includes a large table of the drugs known to be metabolized by the CYP2D6 protein. This list is not comprehensive for all of the drugs in the pharmacopeia but focuses on commonly used drugs with high levels of evidence that the CYPs (CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP3A4 and CYP3A5 only) and other select genes are relevant to a given drug’s metabolism.

The number of people with low CYP2D6 activity is substantial, when one considers the people genetically deficient in CYP2D6, plus the many patients who are taking CYP2D6 inhibitors. For example, for codeine and some other pain relievers: 1. Here is a partial list of drugs metabolized by CYP2D6: dextromethorphan (cough syrup) hydrocodone; methadone; tamoxifen (breast cancer, estrogen blocker) CYP2D6 activity ranges widely within a population comprising ultrarapid (UM), extensive (EM), intermediate (IM) and poor (PM) metabolizer phenotypes. In previous issues of Pharmacy Times we have discussed the cytochrome P450 (CYP450) enzymes CYP1A2, The result of your CYP2D6 test will place you into one of the four groups above. %PDF-1.5 %���� To Make CBD and Drug Interactions Even More Complicated. The cytochrome P450 (CYP)1 enzyme debrisoquine 4-hydroxylase known as CYP2D6 is involved in the oxidative metabolism of many different classes of commonly used drugs, including neuroleptics, tricyclic antidepressants, selective serotonin reuptake inhibitors, β-adrenoceptor blockers, and antiarrhythmics (1)(2). 25% of clinical drug clearance is carried out by this enzyme, which includes antitumor drugs and antipsychotic drugs. The CYP2D6 enzyme metabolizes (breaks down) about 25% of pharmaceutical drugs including SSRIs, opioids, tamoxifen, dextromethorphan, and beta-blockers. Drugs that inhibit CYP2D6 activity are likely to increase the plasma concentrations of certain medications, and, in some cases, adverse outcomes will occur (see Table 3 below right for a list of known inhibitors).

Cytochrome P450 2D6 (CYP2D6) is an important hepatic enzyme involved in the metabolism of 20–25% of clinically used drugs. Although this class has more than 50 enzymes, six of them metabolize 90 percent of drugs, with the two most significant enzymes being CYP3A4 and CYP2D6. CYP2D6: Breaking down medications. Large inter-individual variation in CYP2D6 enzyme activity influences drug efficacy, drug dosages and adverse effects (1). Cytochrome P450 2D6 (CYP2D6) is an enzyme that in humans is encoded by the CYP2D6 gene. Objective: We investigated correlations between clinical efficacy and serum concentrations of rivastigmine and donepezil under special consideration of CYP 2D6 genotype or gene dose-dependent metabolism of donepezil. CYP2D6 also is involved in the activation of some drugs, so these drugs may have reduced efficacy when patients with inadequate CYP2D6 activity take them. Another important property of CYP2D6 is that its activity is affected by genetic variability?some individuals are CYP2D6 deficient; others have normal CYP2D6 activity; and still others have increased activity.
