Description: Ibandronate sodium is a potent bisphosphonate drug developed by Hoffman La Roche and used in the prevention and treatment of osteoporosis and metastasis-associated skeletal fractures in people with cancer. It may also be used to treat hypercalcemia (elevated blood calcium levels). Ibandronate is indicated for the treatment and prevention of osteoporosis in post-menopausal women. In May 2003, the U.S. Food and Drug Administration (FDA) approved Ibandronate as a daily treatment for post-menopausal osteoporosis. Ibandronate is efficacious for the prevention of metastasis-related bone fractures in multiple myeloma, breast cancer, and certain other cancers.

Additional Information

Ibandronate sodium inhibits farnesyl diphosphate synthase (IC50 = 20 nM). Ibandronate sodium is also a bone resorption inhibitor. It has been investigated for in vitro anti-tumor effects, such as apoptosis induction, inhibitor of cell growth, inhibition of invasive behavior, and inhibition of angiogenesis and for its in vivo role in various cancers including breast and prostate cancers.
