Ibandronate sodium is a medication used to prevent and treat osteoporosis, a condition characterized by the loss of bone density and strength, which increases the risk of fractures. It belongs to a class of drugs known as bisphosphonates and works by slowing down the process of bone loss, increasing bone density, and reducing the risk of fractures. Ibandronate sodium is available in tablet form to be taken orally, and also as an injection to be given intravenously. It is typically prescribed for postmenopausal women and men with osteoporosis or osteopenia, as well as for patients receiving glucocorticoid therapy.
