Problems solved by technology

In the above-mentioned preparations, since the addition of sodium sulfite and edetate calcium sodium is harmful to the human body itself, its dosage must be strictly controlled during use, which is likely to bring potential safety hazards; and the above-mentioned raw material formula cannot be fully obtained when it is made into an injection. The stability of the injection solution, the color of the injection, the active ingredients in the prescription, and the pH value will change greatly after long-term storage

Abstract

The invention relates to a compound glycyrrhizin injection preparation which is prepared by glycyrrhizin (or monoammonium glycyrrhizinate), glycine, cysteine hydrochloride, basic amino acid, a pH buffer system and an isotonic regulator. The injection prepared by the prescription has the advantages of stable quality and high safety and can avoid the use of sodium bisulfite and other substances which are easy to produce potential safety hazard.

Description

technical field [0001] The invention relates to a highly stable compound glycyrrhizin injection preparation, which belongs to the technical field of pharmaceutical preparations. Background technique [0002] Compound Glycyrrhizin Injection was first produced by Japan’s Mino Fayuan Pharmaceutical Company (Compound Glycyrrhizin Injection, (Compound Glycyrrhizin Injection), which has been imported to China, and the trade name is “Meineng”. There is Compound Glycyrrhizin Monoammonium Injection in China. Listed, the composition of the main drug is the same as it, but the ratio is different. Compound glycyrrhizin injection includes compound glycyrrhizin injection, compound monoammonium glycyrrhizinate injection, compound ammonium glycyrrhizinate injection, etc. Among them, compound glycyrrhizin injection is also The name is compound glycyrrhizin injection. Compound glycyrrhizin injection powder injection is an improvement of water injection, especially compared to glycine, because...
