Up to 82% of the drug is excreted renally as metabolites [ 5 ]. Based on the test results, our patient is characterized as a CYP2D64/ 41 heterozygote.
WebCYP2D6 is expressed mainly in liver, and although this enzyme represents ∼3% of the hepatic CYP content, it metabolizes ∼20% of drugs. Antidepressants, antiarrhythmics, beta-blockers, and opioid analgesics are typical substrates of CYP2D6. WebThe phase I metabolism of tramadol, shown in Figure 1, is catalyzed by CYP2D6 and CYP3A4, with the O-demethylation reaction to the active M1 metabolite catalyzed by CYP2D6. Approximately 80% of tramadol is metabolized by CYP2D6, an easily saturated, low-capacity, high-affinity enzyme that represents only 1% to 5% of the liver CYP content.
