Alendronate / Fosamax

– Discussion: (see bisphosphonates)     – type of aminobisphosphonate (a synthetic analogs of pyrophosphate) which acts as an inhibitor of osteoclast-mediated bone resorption;     – due to substantial reduction in bone resorption, bone formation exceeds bone resorption at these remodeling sites, which leads to                progressive gains in bone mass;     – this … Read more
