Abstract

The bacteria-free sodium bisulfate-andrographolide powder for injection is prepared with sodium bisulfate-andrographolide powder and through compounding aqua of 0.01-0.5 g/ml concentration and freeze drying. The preparation process of the bacteria-free sodium bisulfate-andrographolide powder for injection is also provided, and the preparation process includes compounding sodium bisulfate-andrographolide aqua of 0.01-0.5 g/ml concentration, filtering with microporous membrane and final freeze drying. The preparation process is simple and suitable for industrial production, and the preparation is stable and favorable to storing and transportation.

Description

technical field [0001] The invention relates to sodium bisulfite andrographolide (lianbizhi) sterile powder for injection and a preparation method thereof; in particular to a freeze-dried powder injection of sodium bisulfite andrographolide and a preparation method thereof. Background technique [0002] Sodium bisulfite andrographolide is a medicinal active ingredient extracted from Chinese herbal medicine andrographolide, which is obtained by adding sodium bisulfite. It has been proved by pharmacological tests to have strong antibacterial activity. It is mainly used in clinical Treat pneumonia, tonsillitis, bacillary dysentery, etc., because of its small side effects, it is especially suitable for children. [0003] Sodium bisulfite andrographolide is currently only produced as an injection (small needle). Because sodium bisulfite andrographolide has a diterpene lactone structure, its aqueous solution is unstable to heat and easy to degrade by ring opening, which affects t...
