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."}]
