Abstract

The invention provides a freeze-dried sodium fusidate powder for injection with double auxiliary materials, relates to the field of pharmaceutical preparations and preparation methods, and mainly solves the problem of excipients in the production formula of sodium fusidate freeze-dried powder for injection in the prior art The disadvantages of long freeze-drying time during production, high drying temperature, high energy consumption, and low pass rate of finished product clarity and solution color. The sodium fusidate freeze-dried powder for injection uses double excipients, the excipients include mannitol and hydroxyethyl starch 130 / 0.4, the main drug is sodium fusidate, and the weight ratio of the main drug sodium fusidate to the auxiliary materials 100:100‑100:120, the weight ratio between mannitol and hydroxyethyl starch 130 / 0.4 is 100:70‑100:90. The above main drug and auxiliary materials are used to prepare sodium fusidate freeze-dried powder for injection. The sodium fusidate freeze-dried powder for injection provided by the invention is stable in quality, safe and effective, simple in production process, short in freeze-drying time during production, low in drying temperature, low in energy consumption, high in the clarity of the finished product and high pass rate of solution color .

Description

Technical field: [0001] The invention relates to the field of pharmaceutical preparations and preparation methods, in particular to a freeze-dried sodium fusidate powder for injection with double auxiliary materials and a preparation method thereof. Background technique: [0002] The main drug of sodium fusidate freeze-dried powder for injection is an antibiotic with a steroidal skeleton, which produces a bactericidal effect by inhibiting bacterial protein synthesis, and has a strong effect on a series of Gram-positive bacteria Antibacterial effect. Staphylococci, including strains resistant to penicillin, methicillin and other antibiotics, are highly sensitive to this product. It is mainly used for various infections caused by various sensitive bacteria, especially staphylococcus, such as osteomyelitis, sepsis, endocarditis, cystic fibrosis with repeated infections, pneumonia, skin and soft tissue infections, surgical and traumatic infections, etc. . At present, the exci...
