Abstract

The invention relates to a compound of phosphatide bilineurine powder injection and relative preparation. Wherein, the inventive product can avoid benzenemethanol, to be stably used. And its components contain phosphatide bilineurine, cholate and support agent. The invention uses special method and treatment. The inventive product via frozen and dried is made into white or yellow powder injection, which can be diluted before vein injection.

Description

technical field [0001] The invention relates to the field of pharmacy, in particular to a composition for polyene phosphatidylcholine powder injection for injection and a preparation method thereof. Background technique [0002] Polyene phosphatidylcholine (PPC) is the main component of phospholipids (PL), which contains unsaturated fatty acid bonds on the triglyceride backbone of phospholipids—that is, arachidonic acid (AA) and docosahexa Phosphatidylcholine of enoic acid (DHA). Phospholipids are the basic components of human cells and tissue membranes. They play an important role in the process of cell regeneration. They cannot be synthesized by the human body and must be ingested from the outside world. Therefore, they are called essential phospholipids (EPL). EPL has a stabilizing, repairing and protective effect on liver cell membranes. Based on the fact that in various liver diseases, the ultrastructure of liver cell membrane and mitochondria is damaged and accompani...
