Common use

Alendronate is a bisphosphonate medication used to treat and prevent osteoporosis in postmenopausal women and men, as well as bone loss caused by steroid use. It helps increase bone mass and reduce the risk of fractures, especially in the spine and hips. Alendronate works by slowing down the breakdown of bone, allowing the body to rebuild stronger bone tissue. It is commonly prescribed for long-term bone health maintenance.
