What Is Evista (Raloxifene)?
Raloxifene, also known as Evista, prevents osteoporosis in postmenopausal women. Raloxifene is the first drug in its class approved to prevent osteoporosis. Evista is also used as an anticancer drug to prevent or reduce cancer growth in the breast and uterus. Raloxifene is not a hormone but acts in a similar way. This drug is labelled as a selective estrogen receptor modulator(SERM).
How Raloxifene Works
This drug performs like estrogen in bone tissue to increase bone density, without the negative effects of estrogens. In the bones, raloxifene binds to elements in the cell that cause the beneficial estrogen effect. Bone density is returned to premenopausal levels.
In the breast and uterus, there are two types of cell elements that either increase or decrease estrogen. These cell elements are not found in the bones. Raloxifene binds to the element that prevents estrogen. Unable to feed on estrogen, estrogen-loving cancer cannot spread.
Raloxifene is one of the most studied medications for the menopausal population.
Storage, dosage, and how to use Raloxifene

When taken for preventing osteoporosis, patients are advised to add supplemental calcium and vitamin D. Other possible dietary changes may be advised.
