Trends in Co-Prescribing of Antidepressants and Tamoxifen among Women with Breast Cancer 2004 – 2010

摘要

IntroductionNearly a decade ago, researchers identified a potential interaction between tamoxifen and strong CYP2D6 inhibitors, including several frequently used antidepressants. Based on evidence available at that time, a United States Food and Drug Administration advisory committee recommended tamoxifen’s label be changed in October 2006, noting that postmenopausal women with estrogen receptor-positive breast cancer who are poor CYP2D6 metabolizers by genotype or drug interactions may be at increased risk of cancer recurrence. The impact of accumulating drug risk information on antidepressant use is unknown.
