Abstract

The invention relates to an oral solid preparation containing polyene phosphatidyl choline and a preparation method thereof. The oral solid preparation comprises polyene phosphatidyl choline as a raw material, antioxidants and related accessories necessary for corresponding forming of the preparation. The procedure is as follows: cryogenically comminuting and sieving the polyene phosphatidyl choline, and then pelletizing, granulating and drying under reduced pressure; then adding accessories for the corresponding preparation, thereby obtaining the corresponding oral solid preparation according to the procedure for corresponding forming of the preparation. The finished preparation is convenient for clinical using and has good material liquidity for production and preparation, which leads to an easy operated forming process of corresponding preparation formation with good quality control.

Description

technical field [0001] The invention relates to oral solid preparations (including tablets, capsules, granules, dripping pills, soft capsules, etc.) with polyene phosphatidylcholine as the main raw material, especially a kind of polyene phosphatidylcholine with good fluidity Granular material and its preparation method. Background technique [0002] Polyene Phosphatidylcholine is a soybean extract, a further extract of soybean phospholipids, chemically identical to important endogenous phospholipids. [0003] Modern pharmacological studies have shown that polyene phosphatidylcholine can reduce fat infiltration of liver cells; reduce inflammation; promote liver cell regeneration by increasing RNA and protein synthesis and glycogen content; inhibit collagen production and reduce collagen / DNA ratio and liver hydroxyproline to reduce connective tissue formation; polyene phosphatidylcholine can protect liver sinusoidal endothelial cells and liver cell biofilm from damage, repair...
