Problems solved by technology

Hepatic hydrolyzed peptide can promote protein synthesis, reduce protein decomposition, promote the proliferation and regeneration of normal liver cells, have a good protective effect on liver cell damage induced by carbon tetrachloride, reduce alanine aminotransferase, and promote the recovery of diseased tissues; but the The therapeutic effect of drugs on hepatitis and liver cirrhosis is still very limited. According to the determination of hepatocyte growth-promoting hormone activity (MTT method) in the national drug standard, liver hydrolyzed peptide injection has the vitality of promoting the growth of human liver cells in vitro, but the vitality The stimulation index is only about 2.9

Abstract

The invention discloses a Heparolysate injection pharmaceutical composition. The pharmaceutical composition is prepared from Heparolysate, vitamin C, potassium aspartate and magnesium aspartatse injection and polyethylene glycol 200. Low vitality stimulation indexes and limited treatment effects of the Heparolysate injection are overcome. The invention also discloses a preparation method of the pharmaceutical. The preparation method which has the characteristic of simple technology is suitable for industrialization production.

Description

technical field [0001] The invention relates to a pharmaceutical composition for treating hepatitis and liver cirrhosis, and further provides a pharmaceutical composition for hepatic hydrolysis peptide injection, which belongs to the technical field of biochemical pharmacy. Background technique [0002] The existing "hepatic hydrolysis peptide injection" is a prescription drug in my country, intramuscular injection, used for adjuvant treatment of chronic hepatitis, liver cirrhosis and other diseases. , Nucleic acid, amino acid substances sterile aqueous solution. Hepatic hydrolyzed peptide can promote protein synthesis, reduce protein decomposition, promote the proliferation and regeneration of normal liver cells, have a good protective effect on liver cell damage induced by carbon tetrachloride, reduce alanine aminotransferase, and promote the recovery of diseased tissues; but the The therapeutic effect of drugs on hepatitis and liver cirrhosis is still very limited. Accord...
