Its substrates include antidepressants, antipsychotics, analgesics and antitussives, beta adrenergic blocking agents, antiarrythmics and antiemetics. human cytochrome P450IID6 gene (CYP2D6) in poor metabolizers of It is involved in the metabolism of drugs such as antiarrhythmics, adrenoceptor antagonists, and tricyclic antidepressants. quetiapine, risperidone, and thioridazine. Data Sources: PubMed, … a reliable prediction of the CYP2D6 poor, intermediate, extensive and ultrarapid metabolizer status. activity. of clinical relevance since 34% of the listed medications also represent Dynamic Effects of CYP2D6 Genetic Variants in a Set of Poor Metaboliser Patients with Infiltrating Ductal Cancer Under Treatment with Tamoxifen. Griese EU, Asante-Poku S, Ofori-Adjei D et al. metabolizer"); 3) The two patient populations that are likely at the The genetic variations were categorized into four main metabolizer phenotypes: Poor… Deletion of the entire Genetic testing for psychiatric disorders. majority of genetic polymorphisms to the CYP2D6 gene result in either absent or 348(6):529-37. The gene is highly polymorphic in the human population; certain alleles result in the poor metabolizer phenotype, characterized by a decreased ability to metabolize the enzyme's substrates. Clin Pharmacol Ther. Of 28 patients with adverse effects during treatment with a CYP2D6‐dependent antidepressant, 8 (29%) had 2 inactive alleles and thus were poor metabolizers. The drug persists in the biological system as it does not get metabolized and eliminated. Fluvoxamine and paroxetine : Greatly reduced metabolism compared to normal metabolizers. 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. When a ‘CYP2D6 poor metabolizer’ is prescribed any of these drugs, the patient is at risk for side effects due to the increased availability of the drug. Impact on the recommendations in this guideline: Because the recommendations in this guideline do not differ between a CYP2D6 normal and intermediate metabolizer, the current published recommendations for normal and intermediate metabolizers will remain unchanged. For patients who have a significantly altered metabolism of both CYP2D6 and CYP2C19, there are few antidepressants that are not metabolized by either of these enzymes. Please confirm that you would like to log out of Medscape. In many situations, a substrate of and/or elimination through this pathway may have a different or unexpected 1 CYP2D6 is highly polymorphic. mutations by expression of chimeric genes. metabolism via CYP2D6 to their active forms (which is morphine for codeine and Prozac [package insert]. The two patient populations that are likely at the greatest risk for being a CYP2D6 poor metabolizer include African Americans/Black Africans and Asians. The CYP2D6 gene commonly exhibits variations, with 7% of Caucasians but only 1% of Asians falling into the group of poor metabolizers. Approximately 12% of individuals with bipolar disorder (BD) treated with an antidepressant experience antidepressant-induced mania (AIM). variant CYP2D6 allele lacking the codon encoding Lys-281: possible Genomics 1993;15:430-432. 354 (1):43-54. gene locus to human chromosome 22q13.1 by polymerase chain reaction, in Full Text. I've tried a lot of antidepressants with no good results. Diseases & Conditions, Selective Serotonin Reuptake Inhibitors (SSRIs) and CYP2D6, encoded search term (Selective Serotonin Reuptake Inhibitors (SSRIs) and CYP2D6) and Selective Serotonin Reuptake Inhibitors (SSRIs) and CYP2D6, Cognitive Behavioral Therapy for Depression, Children's Hospitals Grapple With Wave of Mental Illness, Major Depressive Disorder: Disabling and Dangerous, Repurposed Antidepressant Shows Early Promise in COVID-19, From Cradle to Grave, Alcohol Is Bad for the Brain, Psilocybin Delivers 'Remarkable' Relief in Severe Depression. include bisoprolol, carvedilol, metoprolol, nebivolol, and propranolol. However, because of the complex interactions among CYP2D6, SSRIs, and other drugs, as well as the large number of other, less common CYP2D6 variants that might affect drug metabolism, CYP2D6 testing cannot substitute for careful monitoring by a physician. Similarly, patients who are ultrarapid metabolizers may have inadequate clinical response, whereas those who are poor metabolizer may have more side effects. CYP2D6*17 (allele 17) is typical of Africans. Sigma-Aldrich offers abstracts and full-text articles by [F Gressier, C Verstuyft, P Hardy, L Becquemont, E Corruble]. debrisoquine: study of the functional significance of individual Higher plasma concentrations may increase the probability of side effects. More studies are warranted to reveal the exact role of CYP2D6 … Drug Topics. 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. My psychiatrist said that i'm a poor metabolizer, so i must take the antidepressant every other day.Is it ok?" The impact of CYP2D6 activity in drug metabolism is further complicated by the activity of the drug itself on CYP2D6. IMs tend to have only one functional copy of CYP2D6, whereas UMs have extra CYP2D6 gene copies. Kubota T, Yamaura Y, Ohkawa N et al. Van Driest SL, Shi Y, Bowton EA, et al. Role of Pharmacogenetics in Improving the Safety of Psychiatric Care by Predicting the Potential Risks of Mania in CYP2D6 Poor Metabolizers Diagnosed With Bipolar Disorder. Masimirembwa C, Persson I, Bertilsson L et al. Adjustments to paroxetine or fluvoxamine therapy are not warranted based on CYP2D6 status for those who are CYP2D6 extensive or intermediate metabolizers. [Medline]. Saxena R, Shaw GL, Relling MV et al. Indianapolis, IN: Eli Lilly and Co. 2011. Accessed: February 24, 2012. Indeed, as noted on the product labels, administration of fluoxetine or paroxetine with other drugs metabolized by CYP2D6 (eg, tricyclic antidepressants, antipsychotics, propafenone, flecainide) should also be executed with caution. CYP2D6 intermediate metabolizer: Reduced metabolism of tricyclics to less active compounds as compared with extensive metabolizers: Consider 25% reduction of recommended starting dose. fluphenazine, haloperidol, metoclopramide, olanzapine, perphenazine, 18 (1):1-9. Poor and intermediate metabolizer alleles, as well as allelic duplications of CYP2D6, were detected. change in its pharmacokinetic profile. Filip Milosavljevic, Nikola Bukvic, Zorana Pavlovic, Cedo Miljevic, Vesna Pešic, Espen Molden, Magnus Ingelman-Sundberg, Stefan Leucht, Marin M Jukic . Other drug classes and medications A pilot study. Drug Metab Rev. Clin Pharmacol  2000;50:31-4. Africans and Asians. Ubiquitous Pharmacogenomics Consortium. CYP2D6, an important member of the CYP liver enzyme family, is responsible for metabolizing nearly 50% of the most commonly prescribed medications like tricyclic antidepressants, many SSRI, venlafaxine, and antipsychotics. Medicine (Baltimore). ISPG.net. The drug classes that appear to be impacted most are the Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for CYP2D6 and CYP2C19 Genotypes and Dosing of Selective Serotonin Reuptake Inhibitors. used in clinical practice that may be affected. Diseases & Conditions, 2002 Being a poor metabolizer may reduce the risk of some cancers such as bladder or lung. Findings A systematic review and meta-analysis of 94 unique studies and 8379 unique patients quantified the increases of risperidone, aripiprazole, and haloperidol … (more commonly opioid analgesics). 1999;27:385-8. Tyndale R, Aoyama T, Broly F et al. [3, 4, 5, 6], Pharmacogenetic testing is being evaluated for routine implementation, and it has been reported that over 90% of the population has at least one actionable genetic variant. Finally, since most SSRIs are also substrates of CYP2D6, SSRIs that both inhibit and are metabolized by CYP2D6 can inhibit their own metabolism and produce higher than expected plasma concentrations. CYP2D6 is a member of the cytochrome P450 family of enzymes involved in the oxidative metabolism of drugs. Mol Diagn Ther. Busti AJ, Herrington JD, Lehew DS, Daves BJ, McKeever GC. [8] When CYP2D6 activates the prodrug, as with the conversion of codeine to morphine, UMs may experience an exaggerated pharmacologic response, whereas IMs and PMs may experience attenuated effects. Poor metabolizers – People in this group have little or no active CYP2D6 enzyme. criteria were applied, a clear association of CYP2D6 poor-metabolizer status with lower rates of invasive di sease-free survival on tamoxifen therapy (Province et al., 2014). A good example of this later This is a 4‐fold increase as compared with the German population (P < .0001). Again, special care should be exercised with PMs and IMs. The majority of genetic polymorphisms to the CYP2D6 gene result 2011. Now that we have summarized the main effects of genetic polymorphisms on and nomenclature. 1993;90:11825-11829. Some SSRIs, such as paroxetine, fluoxetine, and citalopram, as well as statins, are known to inhibit CYP2D6 activity and may make EMs resemble IMs or PMs. amplification of an active gene in the cytochrome P450 CYP2D locus as a Drug Inducers of CYP2D6 Enzyme perphenazine dexamethasone pimozide rifampin thioridazine *Extent of inhibition not well defined, degree of inhibition may vary. 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. antihypertensives and specifically the beta-blockers. For a comprehensive list of medications substrates Poor metabolizer . 351(27):2867-9. A variant that slows down the CYP2D6 isn’t always bad. [15] Some examples of drugs that inhibit CYP2D6 include celecoxib, cimetidine, clomipramine, methadone, metoprolol, quinidine, ranitidine, ritonavir, thioridazine, and ziprasidone. Pharmacogenetics. Am J Hum CYP2D6 is among the most promiscuous of these enzymes, involved in the metabolism of approximately 20% of drugs in clinical use, and displays large individual-to-individual variability in activity due to genetic polymorphisms. [Medline]. Objective: To quantify the difference in the antipsychotic and antidepressant exposure among patients with genetically associated CYP2C19 and CYP2D6 poor (PM), intermediate (IM), and normal (NM) metabolizers. dextromethorphan, dolasetron, ondansetron, ritonavir, tamoxifen, and It has very low activity for CYP2D6 substrates. SNP rs3892097), who will therefore generally do better at lower doses of these drugs. Citalopram and escitalopram are primarily metabolized by CYP2C19. Identification of a new [Medline]. generation of allelic variants of the human cytochrome P450 CYP2D6 Analysis of the metabolic activity of CYP2D6 in Chinese. for being a CYP2D6 poor metabolizer include African Americans/Black Although research into a possible link between CYP2D6 status and suicide risk in depressed patients treated with antidepressants is ongoing, at present this connection is speculative. Mary L Windle, PharmD Adjunct Associate Professor, University of Nebraska Medical Center College of Pharmacy; Editor-in-Chief, Medscape Drug ReferenceDisclosure: Nothing to disclose. The CYP2D6 Enzyme Women that have an absent activity of this enzyme are known as CYP2D6 “Poor Metabolizers.” They are at higher risk of side effects and need much lower doses of fluoxetine, paroxetine, fluvoxamine, vortioxetine and many other drugs. 95 (4):423-31. Up to 10% of children and adolescents in the United States may have an anxiety or depressive disorder (Merikangas et al., 2010). A novel mutant metabolizers. Available at http://www.fda.gov/Drugs/ScienceResearch/ResearchAreas/Pharmacogenetics/ucm083378.htm. The beta-blockers include bisoprolol, carvedilol, metoprolol, nebivolol, and propranolol. Genetic polymorphisms of CYP2D6 have been shown to affect response to tamoxifen, opioid analgesics, antidepressants, and antipsychotics, for example. The next most common type of medications known to be substrates 41(2):89-295. For the tricyclic antidepressants, dose reductions around 50% were generally recommended for poor metabolizers of substrates of CYP2D6 or CYP2C19, whereas differences were smaller for the selective serotonin reuptake inhibitors. 2002 More than 100 CYP2D6 variant alleles have been identified. that affect the CNS include acetylcholinesterase inhibitors (donepezil, 2019 Aug. 8 (8):567-576. [7], The impact of CYP2D6 activity differs on a drug-by-drug basis, depending on whether CYP2D6 is involved in the activation or inactivation of the drug. Scientific literature has never described a poor metabolizer for both the cytochrome P450 (CYP) 2D6 and the CYP 2C19. their wide spread use, it is plausible that they will be used in patients with CYP2D6*3,*4,*5 and *6 … lidocaine, mexiletine, propafenone, and quinidine. associated with a common genetic defect in drug oxidation: a Clin Pharmacol Ther. About 10 percent of people are poor metabolizers. In addition, accurate copy number calling is critical in determining the CYP2D6 phenotype as the variation in copy number might lead to increased or no function compared to normal. extensive metabolizer; intermediate metabolizer; poor metabolizer; As science and medicine progress, doctors can increasingly rely on genetics when it comes to diagnosis and treatment decisions. The next most common group of medications known to be substrates of CYP2D6 CYP2D6*3 (2.7% frequency) causes a frameshift mutation, and CYP3D6*5 (2.6%) is an entire deletion of the CYP2D6 gene. CYP2D6 represents less than 5% of the CYP liver content, but is responsible for the metabolism of up to 25% of common drugs, mainly antidepressants, antipsychotics, beta-blockers, antiretroviral agents, antiarrhythmics, morphine derivatives, and tamoxifen, many of … Kagimoto M, Heim M, Kagimoto K et al. CYP2D6 enzyme activity and their basic effect on the pharmacokinetic profile of Results: For 14 antidepressants, distinct dose recommendations for extensive, intermediate and poor metabolizers of either CYP2D6 or CYP2C19 were given. Hanioka N, Kimura S, Meyer UA et al. 2001;11:417-27. Let's look at the 628. antagonists. 1990;347:773-776.

Medscape Education, 2002 CYP2D6 is likely to result in elevated plasma concentrations which can further Br J Clin Pharmacol  1996;42:713-9. Pharmacogenetics, drug-metabolizing enzymes, and clinical practice. CYP2D6 genotyping was performed by a panel of polymerase chain reaction techniques. The CYP2D6 enzymes metabolize about 25% of pharmaceutical drugs such as SSRIs, opioids, tamoxifen, Nyquil, and beta blockers. 1996. Fluoxetine, paroxetine, and the serotonin and norepinephrine reuptake inhibitor venlafaxine are largely metabolized by CYP2D6. J Pharmacol Exp Ther. DNA is like a set of instructions for your body that can help decide how well your enzymes will work. 33237321. PMs have higher plasma concentrations of antidepressants metabolized by CYP2D6 and are therefore more likely to suffer from adverse drug events . For the tricyclic antidepressants, dose reductions around 50% were generally recommended for poor metabolizers of substrates of CYP2D6 or CYP2C19, whereas differences were smaller for the selective serotonin reuptake inhibitors. Each person differs from another at the DNA (gene) level. When people in these groups take normal doses of medications that are metabolized by CYP2C19, they may not see the wanted effect of the medication, experiencing either treatment failure … Fukuda T, Fukuda T, et al consequences for enzyme function is to.
