What is Fosamax and What Does It Contain?
Fosamax is a medication used to treat and prevent osteoporosis, a condition characterized by weakened bones. Its active ingredient is alendronate sodium [1].
What is the active ingredient in Fosamax?
The sole active ingredient in Fosamax is alendronate sodium [1]. Alendronate belongs to a class of drugs known as bisphosphonates, which work by slowing down bone loss [2].
How does alendronate work to treat osteoporosis?
Alendronate works by inhibiting osteoclasts, which are cells responsible for breaking down bone. By reducing bone resorption, alendronate helps to increase bone mineral density and reduce the risk of fractures [2].
What are the other ingredients in Fosamax tablets?
In addition to the active ingredient, alendronate sodium, Fosamax tablets contain several inactive ingredients. These can vary slightly depending on the specific formulation (e.g., Fosamax vs. Fosamax Plus D), but commonly include:
* Cellulose gel [1]
* Croscarmellose sodium [1]
* Magnesium stearate [1]
* Each tablet also contains a specific amount of alendronate sodium trihydrate equivalent to the labeled amount of alendronate sodium [1].
Fosamax Plus D, which contains both alendronate sodium and cholecalciferol (Vitamin D3), will also include vitamin D3 as an active ingredient and potentially other inactive ingredients specific to its formulation [3].
What is the difference between Fosamax and Fosamax Plus D?
Fosamax Plus D is a combination medication that contains alendronate sodium, the active ingredient in Fosamax, along with cholecalciferol (Vitamin D3) [3]. This formulation is prescribed for individuals who may also have a vitamin D deficiency, as vitamin D is crucial for calcium absorption and bone health [3].
