Fosamax is a brand (trade) name for alendronate. Alendronate strengthens bones and may be used for the treatment or prevention of osteoporosis. Alendronate works by inhibiting osteoclasts which are responsible for breaking down and reabsorbing bone (by a process known as bone resorption).

Can Fosamax be used to slow the progression of osteoporosis?

By slowing or stopping the bone-resorbing portion of the remodeling cycle, bisphosphonates allow new bone formation to catch up with bone resorption. Fosamax and other drugs such as Actonel, Boniva, and Reclast increase bone density and help prevent and treat osteoporosis and/or reduce the risk of fractures.

Is Fosamax worth taking?

March 17, 2004 - There is good news about the drugs used to treat and prevent osteoporosis-related bone loss. The longest-ever study of one of the most widely prescribed of these drugs suggests it continues to protect bones after a decade of use.
