Ceftizoxime sodium compound preparation

Technical field: [0001] The invention relates to a compound drug preparation, in particular to an antibacterial compound drug preparation containing ceftizoxime or a physiologically acceptable salt thereof and a β-lactamase inhibitor. Background technique: [0002] Ceftizoxime sodium (Ceftizoxime, czx) is a semi-synthetic third-generation cephalosporin, which is effective for most G - Bacteria, G + Both bacteria and anaerobic bacteria have antibacterial activity and have broad-spectrum antibacterial activity. Due to the increased isolation rate of β-lactamase-producing bacteria, the antibacterial activity of cephalosporin products decreased, and ceftizoxime sodium was no exception. [0003] β-lactamase inhibitors can specifically inhibit the production of β-lactamase, so that the resistant antibacterial substances can regain their antibacterial effect. Therefore, the development of compound preparations containing enzyme inhibitors is an effective measure to solve the mec...
