Example Embodiment

[0014] Example 1

[0015] Take the water for injection, let it cool to 30°C, add glycine, arginine, lactose and mannitol according to the prescription amount described in Table 1, and stir to dissolve. Adjust the pH of the solution to 8.0-9.0, add sodium fusidate in the prescribed amount in Table 1, stir to dissolve, and add water for injection to the full amount. Add the special activated carbon for injection to the liquid, stir for 15 minutes, decarbonize and filter. 0.22~0.45μm microporous filter membrane for precise filtration and sterilization, filled with medicinal solution, half-crushed, freeze-dried, out of the box, press-plugged and capped. Reconstituted with buffer solution (components and content: disodium hydrogen phosphate 196mg, citric acid 10mg, EDTA-2Na 5mg, total 10ml), the compatibility with 5% glucose injection and 0.9% sodium chloride injection is selected and stable. Final dosage of agents and excipients. The results of the study are shown in Table 1:

Abstract

The invention discloses a sodium fusidate freeze-dried powder injection, including the following components and contents (weight portions) of 450 to 550 of sodium fusidate, 30 to 500 of glycin and 40 to 600 of arginine. The sodium fusidate freeze-dried powder injection has good long-period stability and improves the medication safety for the patient and reduces the medication risk, because certain quantity of stabilizer is added into the sodium fusidate freeze-dried powder injection.

Description

technical field [0001] The invention relates to a freeze-dried powder injection of sodium fusidate. Background technique [0002] Sodium fusidate is an antibiotic with a steroidal skeleton. It is mainly used for staphylococcal infections. It is especially suitable for strains resistant to other antibiotics. It is often used for skin, bone tissue and joint infections and endocarditis. [0003] Since sodium fusidate is compatible with 5% glucose or 0.9% sodium chloride, insoluble flocs will appear, and sodium fusidate is unstable in solution, so the sodium fusidate products currently on the market are all Freeze-dried powder for injection is dissolved in the attached special alkaline buffer salt solvent to solve the problem of product compatibility. However, the long-term stability of the product is poor after freeze-drying, and related substances are likely to exceed the standard in long-term storage, and turbidity is likely to occur when it is used in combination, which dir...
