Osteoporosis

Highlights

Drug Approvals

• In 2007, the Food and Drug Administration (FDA) approved zoledronic acid (Reclast) for postmenopausal osteoporosis treatment. Zoledronic acid is given as an injection once a year. A 2007 study in the New England Journal of Medicine indicated that zoledronic acid can significantly reduce the risk of spine, hip, and other fractures.
• In 2007, the FDA approved raloxifene (Evista) for prevention of breast cancer in postmenopausal women with osteoporosis and postmenopausal women at high risk for breast cancer. Raloxifene was previously approved for prevention and treatment of osteoporosis.

Calcium and Vitamin D for Osteoporosis Prevention

• In 2007, the Food and Drug Administration proposed allowing manufacturers of food and supplements to put a health claim on their products stating that the combination of calcium and vitamin D can reduce the risk of osteoporosis.
• In 2007, the National Osteoporosis Foundation updated its daily intake guidelines to recommend 1,200 mg of calcium, and 800 - 1,000 IU of vitamin D3, for adults age 50 and older.
• Calcium plus vitamin D is effective in preventing osteoporosis in people age 50 years and older, according to a 2007 review in the Lancet. The researchers found that a minimum of 1,200 mg of calcium and at least 800 IU of vitamin D per day gave the most protection.

Fosamax: Taking a Break (Without Breaking a Bone)

Women at low risk for fracture may be able to temporarily stop taking alendronate (Fosamax) after 5 years, suggests a 2006 study in the Journal of the American Medical Association.

Antidepressants and Osteoporosis Risk

Selective serotonin reuptake inhibitors (SSRIs), the most commonly used class of antidepressants, may increase the risk for bone loss in both older men and women, according to several studies published in 2007 in the Archives of Internal Medicine. SSRIs include fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil). The researchers did not find that other types of antidepressants are associated with reduced bone mineral density.
