Description :
Cholecalciferol is a vitamin D3. Cholecalciferol is the naturally occurring form of vitamin D. It is a prehormone that is synthesized naturally in the skin by ultraviolet B irradiation of 7-dehydrocholesterol. Cholecalciferol is real vitamin D. All other compounds are either metabolic products or chemical modifications.Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.
A combination of cholecalciferol and alendronate was approved by FDA for the treatment and prevention of osteoporosis.
Action :
Cholecalciferol is vitamin D3 which is required for normal bone formation. It is converted to 25-hydroxyvitamin D3 in the liver and then further converted to 1,25-dihydroxyvitamin D3 (calcitriol) in the kidney. This conversion is stimulated by parathyroid hormone and hypophosphatemia. As a result, 1,25-dihydroxyvitamin D3 increases the absorption of calcium and phosphate in the intestines.
Use :
Cholecalciferol is used to treat or prevent many conditions caused by a lack of vitamin D, especially conditions of the skin or bones.
Cholecalciferol may also be used for other purposes not listed in this medication guide.
