Механизм действия

Calcifediol anhydrous primarily binds to the vitamin D receptor (VDR), activating downstream signaling pathways, thereby exerting its effects on calcium and phosphorus metabolism and bone health. It is the primary metabolite of vitamin D₃ in the liver and is further converted to its active form, calcitriol (1,25-dihydroxyvitamin D₃), in the kidneys. This calcitriol regulates intestinal absorption of calcium and phosphorus, maintaining stable blood calcium and phosphorus levels.

Medical Applications

Osteoporosis: Used for the prevention and treatment of osteoporosis, increasing bone density, and reducing the risk of fractures.

Rickets and Osteomalacia: Used for the prevention and treatment of rickets in children and rickets in adults, promoting normal bone development and mineralization.

Other Diseases: Shows potential benefits in the prevention and treatment of certain autoimmune diseases, cardiovascular diseases, and certain cancers.
