August undefined, 2024

All bisphosphonate drugs share a common phosphorus-carbon-phosphorus "backbone": The two PO 3 (phosphonate) groups covalently linked to carbon determine both the name "bisphosphonate" and the function of the drugs. Bis refers to the fact that there are two such groups in the molecule. The long side-chain (R in the diagram) determines the chemical properties, the mode of action a…

Risedronic acid: Uses, Interactions, Mechanism of Action

WebRisedronate is a pyridine-based bisphosphonate that inhibits bone resorption caused by osteoclasts Label. Mechanism of action Risedronatic acid binds to bone hydroxyapatite Label. Bone resorption causes local acidification, releasing risedronic acid which is that taken into osteoclasts by fluid-phase endocytosis 1. WebIt is in the bisphosphonate family of medications. [3] It works by blocking the activity of osteoclast cells and thus decreases the breakdown of bone. [3] Zoledronic acid was patented in 1986 and approved for medical use in the United States in 2001.
