Problems solved by technology

However, the invention has the following defects: ① the preparation process is complex, the production cycle is long, and the production cost is high; ② during the preparation process, faropenem sodium needs to be dissolved in water and then freeze-dried, and faropenem sodium is extremely sensitive to water, and the dissolution process caused The increase of the polymer; and its stability in the storage process mainly lies in the vacuum environment in the vial after freeze-drying, which avoids the influence of moisture and oxygen on it, and does not fundamentally solve the problem of its polymer increase; ③Injection is required, and professionals are required to administer the drug, which is inconvenient to use
[0013] In the prior art, there is no way to provide a faropenem sodium preparation with low polymer content, good stability, simple preparation process, and less toxic and side effects

Abstract

The invention provides a faropenem sodium granule and a preparation method thereof. The faropenem sodium granule contains faropenem sodium, polyvinyl alcohol, dextran and a sweetening agent. The faropenem sodium granule has the advantages of low polymer content, good stability and simple preparation technology.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to faropenem sodium granules and a preparation method thereof. Background technique [0002] Faropenem (Faropenem) is an atypical β-lactam antibiotic, which belongs to the derivatives of carbapenems. Faropenem shows broad-spectrum antibacterial activity against aerobic and anaerobic Gram-positive bacteria and Gram-negative bacteria, especially against drug-resistant Staphylococcus, Enterococcus and other Gram-positive bacteria and Bacteroides and other anaerobic bacteria. The activity is better than the existing oral antibacterial drugs. Faropenem has a good affinity with penicillin-binding protein and good stability of β-lactamase, less drug resistance, mainly used for respiratory system infection, urinary system infection, reproductive system infection, biliary tract infection caused by sensitive bacteria infection etc. [0003] Faropenem sodium, molecular formula...
