NCT00000427

Brief Summary

Alendronate is a drug that blocks or reduces bone loss, while parathyroid hormone (PTH) stimulates the formation of new bone. The purpose of this study is to compare the bone-building effects of PTH alone, alendronate alone, and both PTH and alendronate in men with osteoporosis over a two-and-a-half year period.
