Tamoxifen (Nolvadex) has been used for over 40 years to treat hormone-receptor positive early, locally advanced and metastatic breast cancers. Learn about tamoxifen and other hormone therapies for metastatic breast cancer. Hormone receptor-positive breast cancers need estrogen and/or progesterone (female hormones produced in the body) to grow. Tamoxifen attaches to the hormone receptor in the cancer cell, blocking estrogen from attaching to the receptor. This slows or stops the growth of the tumor by preventing the cancer cells from getting the hormones they need to grow. Tamoxifen is a pill taken every day for 5-10 years.

It's been thought that there are some people who, due to genetic differences, may not benefit from the usual dose of the drug, but more recent research suggests these women do just as well with treatment. Tamoxifen is broken down into endoxifen by the cytochrome P450 enzyme CYP2D6. (There are also other enzymes such as CYP3A4 and others, but CYP2D6 is likely most significant). Anything that reduces the activity of this enzyme (CYP2D6) can result in a reduced amount of the active metabolite, and hence, less benefit. Reduced activity of the enzyme may occur if you are taking some other medications or if you have particular genetic variations that make the enzyme less active.
