NCIt definition : A synthetic, aromatic derivative with anti-estrogenic properties. Similar to the agent
raloxifene, arzoxifene binds to and interacts with estrogen receptors as a mixed estrogen
agonist/antagonist. This agent exhibits greater bioavailability and higher anti-estrogenic
potency in the breast than does raloxifene; it exhibits reduced estrogenicity in the
uterus compared with either tamoxifen or raloxifene. Arzoxifene may have beneficial
effects on bone and the cardiovascular system (NCI04);
