Mechanism of action
Alendronate is a bisphosphonate that inhibits osteoclast-mediated bone resorption. By binding to hydroxyapatite crystals in bone, it reduces the activity of cells that break down bone tissue, thereby increasing bone mineral density.

About Fosamax
Fosamax is the original brand of Alendronic Acid, a widely used treatment for osteoporosis. The same active ingredient is also sold as Fosamax Once Weekly, and is provided as a tablet in strengths of 35mg and 70mg. Manufactured by Merck Sharp & Dohme, this medication is designed to support long-term bone health and density.
Buying Fosamax online
Fosamax is registered across 14 markets including the UAE, Singapore and Hong Kong, with availability also in Thailand, Malaysia and the Philippines. Because generic Alendronic Acid is often produced in India, it is far more affordable than the original brand and remains one of the most ordered options online for expats and residents across these regions. This provides a reliable supply for those living far from a well stocked facility who require consistent access to bone health maintenance.
