Abstract

The present invention relates to medicine composition of alprostadil and Chuanhuning / Yanhuning liposome and its preparation process. The nanometer liposome medicine contains the mixture of alprostadil and Chuanhuning / Yanhuning in the weight ratio of 0.1-1.0 to 50-300 in 10.1-80.2 weight portions, the mixture of soybean lecithin and yolk lecithin in the weight ratio of 4 to 1 in 88-440 weight portions, the mixture of cholesterol and beta-sitosterol n the weight ratio of 9 to 1 in 40-200, polyethylene glycol in 4000 15-40 weight portions, sodium glucuronate in 100 -280 weight portions and vitamin C in 160-800 weight portions. The medicine of the present invention may be used in antagonizing pneumonia adenovirus and influenza virus.

Description

technical field [0001] The invention relates to a combination medicine of alprostadil and Chuanhuning / Yanhuning liposome and a preparation method thereof. Background technique [0002] Chuanhuning / Yanhuning are the first-choice anti-pneumonia adenovirus and influenza virus drugs for adults and children in clinical practice. The active metabolites of Chuanhuning / Yanhuning in the body are the same substance, because Yanhuning is the extract of the plant Andrographis paniculata - andrographolide Dehydrated andrographolide succinate half-ester potassium and sodium salt refined through esterification, dehydration, and salt formation, while Chuanhuning is the monopotassium salt of andrographolide half-ester. The existing Chuanhuning and Yanhuning drugs have liver function damage, allergic reaction, and pyrogen-like reaction. After eliminating or improving their adverse reactions, both have broad prospects for clinical application. Contents of the invention [0003] In order to...
