Abstract

A fatty emulsion with high stability and synergistic function contains houttuyninum analog, plant oil, phasphatide and the water for injection.

Description

【Technical field】 [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a fat emulsion, in particular to a fat emulsion of houttuyfonate analogues. 【Background technique】 [0002] There is a class of important components in the volatile oil of the whole herb Houttuynia cordata of the family Houttuynia genus, that is, houttuyniatin analogues. Staphylococcus aureus, Escherichia coli and Sporothrix have obvious inhibitory effects, which can improve the body's immunity, enhance the phagocytosis of white blood cells in patients, increase the level of serum properdin, and improve the body's non-specific immunity. At present, houttuyniatin analogues have been successfully used in chronic bronchitis and other upper respiratory tract infections, as well as gynecological diseases such as vaginitis, pelvic inflammatory disease, and chronic cervicitis. Typical volatile substances of this type are decanoyl acetaldehyde and lauryl acetaldehyde, both o...
