Used primarily to treat osteoporosis in postmenopausal women and men, helping to increase bone mass and reduce the risk of fractures, particularly in the spine and hip. Also prescribed for the treatment and prevention of glucocorticoid-induced osteoporosis and for managing Paget's disease of bone. Works by inhibiting bone resorption through suppression of osteoclast activity, thereby maintaining bone strength and integrity. Typically taken orally on a weekly or monthly basis to improve patient compliance.
