"Anti-resorptive agents are a class of medications that slow down the gradual loss of bone. Estrogen, bisphosphonates, selective estrogen-receptor modulators and calcitonin are all anti-resorptive agents."

"At the beginning of the study, the women's bone mineral density was measured, and they were asked about their use of anti-resorptive agents. They were then followed for seven years."

"The researchers found the use of anti-resorptive agents to be associated with an average 32 percent reduced risk of non-vertebral osteoporosis-related bone fractures. The risk reduction was higher among women with major risk factors for fractures, including a bone mineral density score equal to or less than 2.5 and a history of prior osteoporosis-linked fractures."

"The findings support previous studies that found that these drugs help reduce fractures in women with osteoporosis, said study author Dr. Suzanne Morin, who was slated to present the study Monday at a meeting of the International Bone & Mineral Society in Montreal."

"Another study to be presented at the same meeting
