This trial is conducted to investigate the effects of risedronate on BMD and on bone metabolism in postmenopausal women using anastrozole as adjuvant therapy for hormone-receptor-positive early breast cancer and who are high or moderate risk of fragility fracture. It is also conducted to determine the effects of anastrozole on bone mineral density (BMD) and on bone metabolism in women at low risk of fragility fracture.
NCT00089843 ↗	Bone Loss in Women With Anorexia Nervosa	Completed	National Center for Research Resources (NCRR)	Phase 2/Phase 3	2003-06-01	Women with Anorexia Nervosa have been found to have low bone density. The study will determine whether administration of low doses of a natural hormone, testosterone and/or risedronate, a medication to help prevent bone breakdown will improve or prevent bone loss in this condition.
