|Typical Brand Names:
Fosamax tablets contain the active ingredient alendronic acid (as sodium alendronate), which is a type of medicine called a bisphosphonate. (NB. Alendronic acid tablets are also available without a brand name, ie as the generic medicine.) Bisphosphonates are medicines that prevent the breakdown of bone.
Bone is not a static structure. It is continually shaped, reformed and rebuilt by cells called osteoblasts and osteoclasts. These cells continously deposit and remove calcium and phophorous, stored in a protein network that makes up the structure of the bone. Old bone is broken down by the osteoclasts and new bone is formed by the osteoblasts.
In women at the menopause, blood levels of the female hormone oestrogen start to decrease. This results in an increase in bone breakdown by the osteoclasts, which can lead to a loss of bone density. Bone loss is particularly rapid for the first ten years after the menopause and it may lead to the development of osteoporosis - a condition in which the bones become weak and brittle and break (fracture) more easily.
Osteoporosis can also occur in men and as a result of long-term treatment with corticosteroid medicines such as prednisolone. Other risk factors include smoking, a family history of osteoporosis, early menopause and thin body build.
Alendronic acid is used both to prevent bone loss in people who are at risk of developing osteoporosis, and to prevent fractures in people who already have osteoporosis. The medicine works by binding very tightly to the bone and preventing the calcium being removed by the osteoclasts. This stops the osteoclasts from breaking down the bone, which helps to keep the bones strong and less likely to break.
