Abstract

The invention discloses a polyene phosphatidyl choline freeze dried injection for the treatment of hepatic diseases, which comprises polyene phosphatidyl choline as the main ingredients and pharmaceutically acceptable carrying agents, wherein the carrying agent can be auxiliary solvent selected from sodium cholate, sodium deoxycholate, sodium deoxycholate, hydroxypropyl-beta-cyclodextrin, hydroxyethyl-beta-cyclodextrin and / or methyl cyclodextrin. The injection has higher stability.

Description

technical field [0001] The invention relates to a liver-protecting drug and its preparation, more specifically, the invention relates to a polyene phosphatidylcholine freeze-dried powder injection and a preparation method thereof. Background technique [0002] In recent years, the incidence of fatty liver and acute and chronic hepatitis has been on the rise, and its incidence has reached about 10% of the total population. Fatty liver and acute and chronic hepatitis can lead to liver fibrosis if not treated in time, and can even develop into liver cirrhosis. Clinically, polyene phosphatidylcholine preparations, as a good liver-protecting drug, have achieved good results in the treatment of fatty liver and acute and chronic hepatitis. [0003] Polyene phosphatidylcholine is composed of one molecule of phosphoric acid, two molecules of unsaturated fatty acid and choline. It is a natural choline phosphodiglyceride with excess unsaturated fatty acid, which can protect liver sinu...
