The human hepatic cytochrome P450 2B6 (CYP2B6) is a key enzyme in the metabolism of a growing list of clinically important drugs, environmental chemicals (e.g. Click here to include all copy number data. [40] Patients who are initiating these therapies, or have a history of adverse effects or treatment failure, should be considered for CYP2B6 genotyping. Genetic and several nongenetic factors affect the activity of CYP2B6. You can see. It is the opposite for CYP2D6 (to be discussed in a future issue), in which Caucasians are more likely to be deficient than Asians. Keep in mind that many drugs, toxins, and endogenous substances can be metabolized using multiple different CYP enzymes. Copy number segments are excluded if the total copy number and minor allele values are unknown. displayed. Among its related pathways are Valproic acid pathway and Cytochrome P450 - arranged by substrate type .

You can see additional information about this data in the Cytochrome P450 2B6 (CYP2B6) mediates clinical methadone clearance and metabolic inactivation via N- demethylation to 2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP). Other drugs are turned into their inactive form by CYP2D6. the table may give a value of greater than 100%. panel on the left. Guideline on the Investigation of Drug Interactions. CYP2B6 (Cytochrome P450 Family 2 Subfamily B Member 6) is a Protein Coding gene. Diseases associated with CYP2B6 include Efavirenz, Poor Metabolism Of and Abacavir Allergy . The table below lists therapeutic products from Drugs@FDA with pharmacogenomic information found in the drug labeling. The CYP2B6 enzyme metabolizes a growing number of clinically important drugs such as the anti-HIV drug efavirenz, but its activity in the liver is highly variable, which may lead to failure of therapy or toxicity and unpredictable drug interactions. ), Drug A is metabolized by CYP2D6 and CYP2C9, Drug B inhibits CYP2D6. Note: CYP3A4 is the main enzyme that metabolizes Gleevec and therefore effects may be more pronounced that those related to CYP2D6 Potential drug interactions should be researched, and medication changes should only be made after consulting a health professional. Genetic variants of the drug transporter ABCB1 and the 1236TT-2677TT-3435TT haplotype was significantly associated with non-smoking status. 3A only), or they may be metabolized by a number of CYP enzymes (ex. Primidone Rifampin When drugs classified as ‘substrates’ are co-administered with (Study Agent), there is the potential for higher concentrations of the ‘substrate’. button. based on their structure, Drugs may be metabolized by one subclass of CYP enzyme (ex. reload the genome browser. About 70% of activity of CYP2B6 was suppressed after its incubation with 1.5 μ M IMP for 9 minutes. To include these Note that you can also view the genome browser in a Show more. The role of CYP2B6 in drug metabolism is being increasingly recognized; bupropion, cyclophosphamide, efavirenz, ifosfamide, and methadone are some of the clinically important drugs that undergo metabolism via CYP2B6. rs3745274 You have hidden all of the sections.
