Tamodex

Tamoxifen is a selective estrogen receptor modulator (SERM) and nonsteroidal antiestrogen medication primarily used to treat hormone receptor-positive breast cancer in both men and women, as well as to reduce the risk of developing breast cancer in high-risk individuals.[1] It functions by competitively binding to estrogen receptors in breast tissue, thereby blocking the hormone's stimulatory effects on cancer cell growth, while exhibiting estrogen-like (agonist) activity in other tissues such as bone and the endometrium.[2] Approved by the U.S. Food and Drug Administration (FDA) under the brand name Nolvadex, it is typically administered orally as a tablet or solution once daily, with treatment durations often ranging from 5 to 10 years depending on the indication.[3]
