What's new in the treatment of osteoporosis?
* Fosamax. Approved last week, Fosamax is the first new drug for osteoporosis in 20 years. The drug, chemically known as alendronate, helps to increase bone density.
* Calcitonin nasal spray. The hormone calcitonin, now available as an injectable medication, may soon be approved as a nasal spray. The medication helps slow the rate of bone loss.
* Sodium fluoride. An experimental regimen using a slow-release form of the chemical has shown promise in increasing bone strength and reducing the risk of fracture. A new drug application on slow-release sodium fluoride has been submitted to the FDA.
