The theory appears to be that when two or more drugs use the same metabolic pathway, there must be inhibition of metabolism. too small to provide sufficient statistical power. J Natl Cancer Inst. In addition, multiple studies have shown thatSSRI and SNRI antidepressants are an effective non-hormonal treatment for hot flashes25% of women who are experiencing hot flashes related to tamoxifen therapy are now prescribed antidepressants to manage their symptomsTamoxifen is a SERM (selective estrogen receptor modulator) used in women with breast cancer; it reduces the risk of relapse and improves overall survival and is also used to reduce risk for breast cancer in women at high risk for the disease.
No source of funding was used to prepare this article.The author declares that he has no competing interests.PDH has worked in the field of drug–drug interactions for 50 years. One group of researchers claimed a “high level of evidence” that “there is no need to avoid CYP2D6 inhibitors in postmenopausal patients taking tamoxifen” [Another study from 2016 that found no effect of paroxetine on tamoxifen efficacy stated that the freedom from worry about CYP2D6-inhibiting SSRIs “will help improve the quality of life of breast cancer survivors given that thousands of survivors struggle with depression, sleep disturbance, and vasomotor symptoms while on tamoxifen treatment” [Some authors, perhaps lacking imagination, conclude that although CYP2D6 inhibitors may interact with tamoxifen, in essence that it is “no big deal”. who take these drugs may not benefit from tamoxifen. (Wellbutrin) Cancer Res. enzyme rather than CYP2D6.

Dextromethorphan as a phenotyping test to predict endoxifen exposure in patients on tamoxifen treatment. This is a critical point, because it makes the conflicting data on CYP2D6 activity and tamoxifen efficacy more understandable, perhaps even inevitable.Awareness of the possible impact of enzyme inducers on tamoxifen was advanced by a prospective study in which breast cancer patients on tamoxifen were given rifampin 600 mg/day for 15 days [A case report has also appeared showing a dramatic reduction in endoxifen plasma concentrations in a 39-year-old woman following rifampin therapy [Tamoxifen, endoxifen, and tamoxifen metabolites are substrates for enzymes and transporters that are susceptible to induction, such as uridine diphosphate-glucuronosyltransferases (UGTs), a family of enzymes that catalyse the covalent addition of glucuronyltransferases, CYP3A4, CYP2C9/CYP2C19, CYP2B6, and efflux transporters such as It seems likely, therefore, that the ability of rifampin (and other enzyme inducers, as described below) to reduce endoxifen AUC is via more than one pathway. 2016;27:125–36.Argalacsova S, Slanar O, Vitek P, Tesarova P, Bakhouche H, Drazdakova M, et al.
Future Oncol. clinical trials designed mainly to look at genetic profiles and Although efforts to orchestrate this diverse group to achieve consensus have failed so far, untangling some of the errors and misconceptions about DDI is a necessary step if we are to succeed.Moreover, despite the complexity and the many unanswered questions, I will argue in this commentary that although we do not have enough evidence to establish the importance of tamoxifen DDI with certainty, we clearly have enough data to act.
