Calcifediol Usage
Treatment of various chronic bone disorders, and metabolic bone disease associated with chronic renal failure, hypocalcemia.
Osteosized diol can promote the absorption of Ca2 +, pi in the small intestine, increase the concentration of serum Ca2 +, pi, reduce the levels of alkaline phosphatase and parathyroid hormone in some patients, and reduce the mineral deficiency of some patients. Treatment and prevention of metabolic bone disease and kidney disease, renal dialysis in patients with chronic renal failure hypocalcemia, lack of rickets, various types of male rickets, osteoporosis, anticonvulsants caused by bone Loose and so have a good effect.
