For example, nortriptyline is a common tricyclic antidepressant and a substrate of CYP2D6. This type of drug interaction is probably more frequent than commonly realized, because reduced drug effect may simply be attributed to lack of patient response. CYP3A4 genetic polymorphisms are believed to be one of the important causes, leading to inter-individual variability in drug metabolism. a Strong inhibitor of CYP1A2 and CYP2C19, moderate inhibitor of CYP3A, and weak inhibitor of CYP2D6.

In previous issues of Pharmacy Times, we have discussed the cytochrome P450 (CYP450) enzymes CYP1A2, CYP2C9, CYP2C19, and CYP2D6 (see www.PharmacyTimes.com/Drug Interactions). Cytochrome P450 3A4 (CYP3A4) enzyme activity is known to show considerable ethnic heterogeneity and inter-individual differences, affecting the outcome of drug treatment. The Geeky Medics Clinical Examination Book - OUT NOW! The CYP3A family is the most abundant subfamily of the CYP isoforms in the liver. Published in August 2007. (2010), Hum Genomics, 5(1):61], and the list of references is available here. Inhibitors prevent the CYP450 enzymes from working or reduce the rate of an enzyme-catalysed reaction. (2010), Hum Genomics, 5(1):61]. St Johns wort should not be taken concurrently with oral contraceptive pills or patients should use alternative methods such as barrier methods, depots and intrauterine devices (IUD). Note: Many of these chemical inhibitors are not specific for an individual CYP enzyme. 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. Dabigatran etexilate is a pro-drug and converted by carboxylesterase (CES) to dabigatran which is the measured moiety (dabigatran is not a substrate of P-gp).
