Medicine Description tamoxifen 20mg
Tamoxifen 20mg Tablets is a medication that serves as a selective estrogen receptor modulator (SERM). It exerts its effects by binding to estrogen receptors in breast tissue, thereby inhibiting estrogen's proliferative effects on breast cancer cells. By competitively blocking these receptors, tamoxifen decreases estrogen's ability to promote the growth of hormone-sensitive tumors. This unique mechanism allows tamoxifen to not only treat existing breast cancer but also to play a preventive role in women at high risk for developing the disease, by reducing the likelihood of estrogen-induced tumor formation.
