Considerable variation exists in the efficiency and amount of CYP2D6 enzyme produced between individuals. So, the dose of the drug may have to be adjusted to take into account of the speed at which it is metabolized by CYP2D6. CYP2D6 enzyme expression that will lead to decreased or increased CYP2D6 activity respectively. Pharmacogenomic tests are now available to identify patients with variations in the CYP2D6 allele and have been shown to have widespread use in clinical practice.

The type of CYP2D6 function of an individual may influence the person’s response to different doses of drugs that CYP2D6 metabolizes. The nature of the effect on the drug response depends not only on the type of CYP2D6 function, but also on the extent to which processing of the drug by CYP2D6 results in a chemical that has an effect that is similar, stronger, or weaker than the original drug, or no effect at all. Subjects possessing certain allelic variants will show normal, decreased, or no CYP2D6 function, depending on the allele. Race is a factor in the occurrence of CYP2D6 variability. Where classes of agents are listed, there may be exceptions within the class. File:Catecholamine and trace amine biosynthesis.
