Detailed Description:
Ceftazidime is a third-generation cephalosporins. Ceftazidime sodium and sulbactam sodium for injection (2:1)plays a therapeutic role by the former inhibiting bacterial cell wall synthesis,the latter making irreversible competitive inhibition of β-lactamase.The antimicrobial effect of ceftazidime can be enhanced by the two combined. The compound specifically aims to the mechanism of bacterial resistance, extending the life of ceftazidime in the treatment-resistant pathogen infections.
