Abstract

The invention provides a polyene phosphatidyl choline composition for injection and a preparation method thereof. The composition is composed of methoxy polyethylene glycol-phosphatidyl ethanolamine, cholesterol, water for injection, soybean oil, a glycine-HCl buffer solution, and is prepared through a compound compatibility method. The polyene phosphatidyl choline composition has the advantages of reduced safety hazard and improved drug effect.

Description

technical field [0001] The invention relates to a composition for polyene phosphatidylcholine injection and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] When suffering from liver disease, the metabolic activity of the liver is severely impaired. Polyene Phosphatidylcholines provide high-dose, readily available high-energy polyene phosphatidylcholines that are chemically identical to important endogenous phospholipids. Phospholipids are necessary for the synthesis of lipoproteins by the liver to transport lipids from hepatocytes to peripheral storage. Lack of phospholipids can easily lead to fatty liver due to blocked lipoprotein synthesis. [0003] Polyene phosphatidylcholine mainly enters into liver cells, and combines with liver cell membranes and organelle membranes as a complete molecule, and can be secreted into bile. Therefore, polyene phosphatidylcholine has the following physiological functions:...
