Tamoxifen ist ein selektiver Estrogenrezeptormodulator, der als Arzneistoff zur Therapie von Brustkrebs bei Frauen vor der Menopause eingesetzt wird. Tamoxifen Citrate is the citrate salt of an antineoplastic nonsteroidal selective estrogen receptor modulator SERM. Tamoxifen competitively inhibits the binding of estradiol to estrogen receptors, thereby preventing the receptor from binding to the estrogen-response element on DNA. Tamoxifen is a SERM (selective estrogen receptor modifier). It acts as an estrogen receptor (ER) antagonist in some tissue (in this case, breasts) and an ER agonist in other tissue (in this case, bone and uterus). It is often used for breast cancer treatment for this reason, as it prevents osteoporosis and the spread of estrogen-sensitive cancer in the breasts and can be combined with Gn RH blockers (either Gn RH antagonists or agonists) for treatment. In other words, tamoxifen acts as an anti estrogen in the breasts but as estrogen in bones and skin. This medication would likely be effective in halting breast growth (as it would prevent estrogen from acting in the breasts), and is already used for the treatment of fibrocystic breasts and breast cancer due to lack of side effects compared to other medications like danazol. It can possibly lower levels of IGF-1 (insulin growth factor 1), but also can lead to higher levels of estrogen in the uterus, which could lead to uterine cancer (though the risks are small). Unlike tamoxifen, raloxifene is an ER antagonist in uterine tissue (lowering the risk for uterine cancer), and has a greater ER affinity in bone. Tamoxifen has been proven to lower fibroglandular and breast volume/density in premenopausal women, and it and other SERMS have been proven to move fat distribution from the butt and central region to the legs. Tamoxifen won't work on hormone-receptor-negative breast cancer. Tamoxifen is available in two forms: a pill taken once a day (brand name: Nolvadex) or a liquid form (brand name: Soltamox).

Ask your doctor which type of non-hormonal birth control would be best for you.

Tamoxifen is the oldest of the hormonal therapies, drugs that block the effects of estrogen in the breast tissue. Tamoxifen is approved by the FDA to treat people diagnosed with both early-stage and advanced-stage hormone-receptor-positive breast cancer. Tamoxifen is an antagonist of the estrogen receptor in breast tissue. It has been the standard endocrine anti-estrogen therapy for hormone-positive early breast cancer, although aromatase inhibitors have been proposed for postmenopausal women.
