Each tablet of ALENDRONATE SODIUM + CHOLECALCIFEROL (FOSAVANCE) contains 91.37 mg of alendronate monosodium salt trihydrate which is the molar equivalent to 70.0 mg of ALENDRONATE SODIUM + CHOLECALCIFEROL free acid, and 70 mcg or 140 mcg of cholecalciferol equivalent to 2800 IU or 5600 IU vitamin D3, respectively.
ALENDRONATE SODIUM + CHOLECALCIFEROL (FOSAVANCE) contains alendronate sodium and cholecalciferol (vitamin D3).
Alendronate Sodium: Alendronate sodium is a bisphosphonate that acts as a potent, specific inhibitor of osteoclast mediated bone resorption. Bisphosphonates are synthetic analogs of pyrophosphate that bind to the hydroxyapatite found in bone.
Cholecalciferol: Cholecalciferol (vitamin D3) is a secosterol that is the natural precursor of the calcium regulating hormone calcitriol (1,25-dihydroxyvitamin D3).
