WebMar 16, 2024 · Bisphosphonates work by slowing down the cells which break down bone (osteoclasts). Therefore they slow down bone loss, allowing the bone cells (osteoblasts) that help to build the bone to work more effectively. They can help to strengthen bone and help to prevent it getting any weaker. In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR)2 groups (where R = alkyl, aryl, or just hydrogen). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and common alcohols. Many commercially important compounds are phosphonates, including glypho…

WebNov 27, 2024 · Bisphosphonates are drugs that target areas of higher bone turnover. The osteoclast cells, which break down old bone, absorb the bisphosphonate drug. Their activity is slowed down. This reduces bone breakdown. There are several different types of bisphosphonates, and they each work slightly differently. Bisphosphonates are a class of drugs that prevent the loss of bone density, used to treat osteoporosis and similar diseases. They are the most commonly prescribed drugs used to treat osteoporosis. They are called bisphosphonates because they have two phosphonate (PO(OH) 2) groups. They are thus also called diphosphonates (bis- or di- + phosphonate).
