Vitamin D2 is the chemical name of Ergocalciferol, a form of vitamin D. Ergocalciferol is a secosteroid formed by a photochemical bond breaking of a steroid, specifically, by the action of ultraviolet light on ergosterol.Viosterol, the name given to early preparations of irradiated ergosterol, is essentially synonymous with ergocalciferol .
Function
1) Vitamin D2 is used to prevent vitamin D deficiency and treatment, such as: vegan, parenteral nutrition patients with pancreatic insufficiency malabsorption syndromes, liver and gallbladder disease (liver damage, cirrhosis, obstructive jaundice), intestinal disease (fatty diarrhea, Crohn's disease, chronic diarrhea), stomach resection.
2) Vitamin D2 is used for the treatment of chronic hypocalcemia, hypophosphatemia, rickets associated with chronic renal insufficiency and osteomalacia, familial hypophosphatemia and hypoparathyroidism (surgery, idiopathic or pseudo-hypoparathyroidism)
3) Vitamin D2 is used to treat acute and chronic and post-operative tetany potential disease and idiopathic tetany disease.
Application
1.For the prevention and treatment of vitamin d deficiency. Such as vegans, parenteral nutrition patients, pancreatic dysfunction with malabsorption syndrome, liver and gallbladder diseases (liver damage, liver cirrhosis and obstructive jaundice), intestinal disease (fatty diarrhea, diarrhea in Crohn's, chronic), gastric resection.
2.Used in chronic hypocalcemia, hypophosphatemia, and rickets and osteomalacia associated with chronic renal insufficiency syndrome, familial hypophosphatemia and hypoparathyroidism (false hypoparathyroidism, idiopathic or after) treatment.
3.for the treatment of acute and chronic and potential contraction of the hands and feet and after surgery of idiopathic with contraction of the hands and feet.
