Abstract

The invention discloses an anti-beta-lactamase antibiotic compound preparation, which is specifically a compound preparation composed of cefuroxime and its salt, sulbactam and its salt, or tazobactam and its salt. The weight ratio range of cefuroxime and its salt and sulbactam and its salt or tazobactam and its salt in the compound preparation is 1:1 to 10:1; cefuroxime and its salt and sulbactam and its The preferred weight ratio range of its salt is 2:1 to 6:1, the optimum weight ratio is 4:1, the preferred weight ratio range of cefuroxime and its salt and tazobactam and its salt is 1:1 to 6 : 1, the optimum weight ratio is 2: 1. Compared with cefuroxime, the invention has wider antibacterial spectrum and stronger antibacterial effect.

Description

technical field [0001] The invention relates to an anti-β-lactamase antibiotic compound preparation, in particular to a compound preparation composed of cefuroxime and its salt, sulbactam and its salt or tazobactam and its salt. Background technique [0002] Cephalosporin antibiotics have been widely used clinically and played a positive role in human health. At the same time, due to the long-term and extensive clinical use, the problem of bacterial resistance to cephalosporin antibiotics is becoming more and more serious. The main mechanism of bacterial resistance to cephalosporin antibiotics is the production of specific β-lactamases (β-lactmases) to decompose drugs, including chromosome-mediated type I cephalosporinases and plasmid-mediated extended-spectrum β-lactamase. In order to overcome the clinical drug-resistant infection caused by β-lactamase-producing bacteria, it is of great clinical significance to develop compound preparations of cephalosporin antibiotics an...
