<s>[INST] Are all osteoporosis treatments the same? [/INST] No; each drug has its own features. Nor are all bone resorption reducing agents or antiresorptives (bisphosphonates, denosumab, SERMs and oestrogens) equal; and neither are the bisphosphonates. Although they all initially act on bone-degrading cells (osteoclasts) they do so by different mechanisms. Bone-forming treatment with teriparatide acts on bone-forming cells, known as osteoblasts, whereas the mode of action of antiresorptive treatments involves the cells responsible for degrading, reabsorbing and remodelling bone, these are called osteoclasts.
