Mechanism:

The action of zoledronate on bone tissue is based partly on its affinity for hydroxyapatite, which is part of the mineral matrix of bone. Zoledronate also targets farnesyl pyrophosphate (FPP) synthase. Nitrogen-containing bisphosphonates such as zoledronate appear to act as analogues of isoprenoid diphosphate lipids, thereby inhibiting FPP synthase, an enzyme in the mevalonate pathway. Inhibition of this enzyme in osteoclasts prevents the biosynthesis of isoprenoid lipids (FPP and GGPP) that are essential for the post-translational farnesylation and geranylgeranylation of small GTPase signalling proteins. This activity inhibits osteoclast activity and reduces bone resorption and turnover. The selective action of bisphosphonates on bone is based on their high affinity for mineralized bone. Intravenously-administered zoledronic acid rapidly partitions to bone and localizes preferentially at sites of high bone turnover. The relatively long duration of action of zoledronic acid is attributable to its high binding affinity to bone mineral. In postmenopausal women, it reduces the elevated rate of bone turnover, leading to, on average, a net gain in bone mass.
