Arzoxifene hydrochloride

Pronunciation

Definition 1

A substance being studied in the treatment of osteoporosis and breast cancer. Arzoxifene hydrochloride is made in the laboratory and binds to estrogen receptors in the body. It is a type of selective estrogen receptor modulator (SERM). Also called LY353381 hydrochloride. (NCI Dictionary)

Definition 2

The hydrochloride salt of arzoxifene, a synthetic aromatic derivative with anti-estrogenic properties. Arzoxifene binds to estrogen receptors as a mixed estrogen agonist/antagonist. In comparison to other selective estrogen receptor modulators (SERMs), arzoxifene exhibits greater bioavailability and higher anti-estrogenic potency in the breast than raloxifene; it exhibits reduced estrogenicity in the uterus compared with either tamoxifen or raloxifene. This agent may have beneficial effects on bone and the cardiovascular system. (NCI Thesaurus)
