Cloxacillin Sodium is an organic compound with the molecular formula C 19 H 18 Cl2N3NaO6S. It is a white powder or crystalline powder; slightly smelly and bitter; hygroscopic. Cloxacillin sodium is prepared into an injection for administration, which is mainly used to treat penicillinase-producing Staphylococcus aureus infections, including sepsis, endocarditis, pneumonia, and skin and soft tissue infections. Because it has multiple easily hydrolyzed groups, such as β-lactam rings and amide bonds, it has poor stability and is easily hydrolyzed. In order to improve the stability of cloxacillin sodium, the present invention uses Bicine (N,N-bis(hydroxyethyl)glycine) as a buffer salt and CMC / AA / AM as a hygroscopic agent (carboxymethyl cellulose (CMC) connected to acrylic acid (AA) connected to acrylamide (AM)), and adopts a sterile packaging process to obtain a highly stable cloxacillin sodium preparation.
