WebEven though the promotion of osteoclasts’s apoptosis represents the main mechanism of action of bisphosphonates, 2 osteoblasts have been shown to play an important role in bone homeostasis as well. 32 These cells regulate bone metabolism by directly interacting with osteoclasts through direct cell-cell contact, cytokines and extracellular ... WebThe mechanism of action for suppressing bone resorption is the inhibition of farnesyl pyrophosphate synthase, a key enzyme in the mevalonic acid metabolic pathway of osteoclasts, to induce apoptosis of the cells. Minodronate is the strongest inhibitor of bone resorption among the currently available oral bisphosphonates. WebMany of the bisphosphonates are very powerful inhibitors of bone resorption. This is seen both in normal animals and in animals where bone resorption is simulated by various means.
