Details
Toremifene, 2-[4-[(1Z)-4-chloro-1,2-diphenyl-1-butenyl]phenoxy]-N,N-dimethylethanamine(Fareston), differs structurally fromtamoxifen only by having a chloroethyl group (rather than anethyl group) attached to the triphenylethylene structure. Asmight be expected, the pharmacological actions of toremifeneand tamoxifen are quite similar. Toremifene is also a SERM,with estrogen antagonist action in breast tissue but agonist actionin the endometrium, on bone tissue, and on serum lipidprofiles. Recent clinical data indicate that the incidence ofendometrial cancer is lower with toremifene use than with tamoxifen. Toremifene is used in the treatment of metastaticbreast cancer in postmenopausal women.
Toremifene citrate tablets are suitable for postmenopausal women with estrogen receptor-positive or unknown metastatic breast cancer.
