Pharmacology

Toremifene Citrate is the citrate salt of a nonsteroidal triphenylethylene antiestrogen. Chemically related to tamoxifen, toremifene is a selective estrogen receptor modulator (SERM). This agent binds competitively to estrogen receptors, thereby interfering with estrogen activity. Toremifene also has intrinsic estrogenic properties, which is manifested depending on the tissue or species. (NCI04)
