Promise and Progress - Possible Interaction Identified Between Tamoxifen and Hot Flash Drug
Possible Interaction Identified Between Tamoxifen and Hot Flash Drug
Date: June 1, 2004
Journal of National Cancer Institute, December 3, 2003
Researchers are investigating interactions between the commonly used breast cancer drug tamoxifen and the antidepressant drug paroxetine, used to treat hot flashes. The interactions could potentially alter the effectiveness of tamoxifen. A team of scientists from the Johns Hopkins Kimmel Cancer Center, Indiana University and the University of Michigan found that women taking both drugs had decreased levels of a newly identified molecule called endoxifen, a byproduct of tamoxifen in its processed form, which could indicate that the tamoxifen is not being fully metabolized in these people.
“Right now, these results do not change current treatment recommendations for women on adjuvant tamoxifen therapy who are dealing with hot flashes,” says Vered Stearns, M.D., assistant professor of oncology at the Kimmel Cancer Center and lead investigator in the study. “We need larger studies to understand the impact of endoxifen and CYP2D6 on tamoxifen’s effectiveness.”
