M05BA04 • alendronic acid • Musculo-skeletal system | Drugs affecting bone structure and mineralization | Bisphosphonates

Alendronic acid is a medication used for the prevention and treatment of osteoporosis, a condition characterized by decreased bone density and an increased risk of fractures. It is particularly indicated for postmenopausal women, men at risk of bone loss, and patients undergoing long-term corticosteroid therapy.

Alendronic acid belongs to the bisphosphonate class and works by inhibiting bone resorption, reducing the activity of osteoclasts (cells that break down bone). This helps maintain bone density and reduces the risk of fractures, especially in the hip and spine.

Side effects may include esophageal irritation, abdominal pain, nausea, or heartburn. To minimize these risks, the medication should be taken in the morning on an empty stomach with a full glass of water, and the patient should remain upright for at least 30 minutes after administration.
