DescriptionVitamin D2, Vitamin D2), chemical name for 9, 10 - open loop ergot steroid - 5, 7, 10 (19), 22-4-3 beta - alcohol. Colorless needle crystal or white crystalline powder; Odourless, tasteless; With light or air are perishable. For the prevention and treatment of vitamin D deficiency, chronic hypocalcemia, low phosphorus, rickets and osteomalacia associated with chronic renal insufficiency, familial low phosphorus and low parathyroid function (postoperative parathyroid function), idiopathic or sham treatment, used in the treatment of acute and chronic and potential tetany disease and idiopathic tetany after surgery.
Functions and UsageAs a kind of vitamin medicine, it takes part in the metaboly and the absorption of calcium and phosphorus, the acceleration of the calcification of bone matrix. Used for rachitis, osteomalacia and poor performance of parathyroid gland, specially for hypogenesis of children, calcium deficiency in duration of pregnancy, osteoporosis of old people.
