Problems solved by technology

[0016] In addition, it is known that in clinical use, turbidity or precipitation will occur when the drug is mixed or encountered with sodium fusidate
The reasons may be: 1) Drugs with strong acidity, such as vitamin C, ligustrazine phosphate, etc., can cause fusidic acid to separate out from sodium fusidic acid due to lowering the pH of the solvent, forming turbidity or precipitation, so the choice of solvent It should be noted that if the pharmacopoeia stipulates that the pH range of glucose injection is 3.5-6.5, sodium fusidate is likely to precipitate in this pH range.
2) It may combine with fusidic acid to form a double salt with less solubility, which is easy to form turbidity or precipitation
[0017] It has been found that sodium fusidate prepared by existing methods is unsatisfactory in certain pharmaceutical properties, such as their chemical stability
