Abstract

The invention relates to Vitamin D2 solid dispersion coated tablet and the preparation method thereof, belonging to pharmaceutical preparation technical field. The tablet contains Vitamin D2 and pharmaceutical excipient, with Vitamin D2 as the active component. Every ten thousand tablets contain 0.3125g of Vitamin D2, 100g of PEG-6000, 2500g of starch, 2250g of phosphoric acid calcium hydrogen, 75ml of alcohol, 100g of magnesium stearate and 50g of talc. The invention has a simple preparation method, according to which Vitamin D2 is coated to produce tablets. The Vitamin D2 tablets prepared in the method has obvious treating effects and can be taken orally. The toxicity is low and the bioavailability is greatly enhanced. Besides, the tablet has the functions of sustaining, targeting, energy provision for human organism, etc.

Description

technical field [0001] The present invention relates to vitamin D 2 A solid dispersion coated tablet and a preparation method thereof belong to the technical field of pharmaceutical preparations. Background technique [0002] A lack of vitamin D in the body can cause rickets, tetany and rickets. Vitamin D mainly has the following physiological functions: (1) Improve the body's absorption of calcium and phosphorus, and make the levels of plasma calcium and phosphorus reach saturation. (2) promotes growth and bone calcification, and promotes healthy teeth; (3) increases phosphorus absorption through the intestinal wall and increases phosphorus reabsorption through the renal tubules; (4) maintains normal levels of citrate in the blood; (5) Prevents loss of amino acids through the kidneys. [0003] Vitamin D 2 It is mainly used for the treatment of rickets, tetany and rickets. Vitamin D 2 It is an essential vitamin for the human body and belongs to steroid hormones. Its ma...
