Abstract

The antibiotic medicine composition is mixture of cefpiramide and beta-lactamase inhibitor in the weight ratio of 1 / 3 to 10. The cefpiramide may be replaced with alkali metal salt of cefpiramide or the mixture of cefpiramide, sodium carbonate and arginine. The beta-lactamase inhibitor may be clavulanic acid or its derivative, sulbactam or its derivative, or tazobactum or its derivative. The antibiotic medicine composition has high antibiotic effect, especially on sensitive bacteria and zymogenic bacteria, and wide antibiotic spectrum.

Description

technical field [0001] The invention belongs to the technical field of medicine and relates to a group of novel antibacterial drug compositions. Background technique [0002] Cefpiramide (Cefpiramide) is a semi-synthetic third-generation cephalosporin antibiotic. Its chemical structure is characterized by a methylthiotetrazolyl group at the 3-position side chain of the cephem core, and a hydroxyphenyl group and a hydroxyl group at the 9-position side chain. picoline. This product has the characteristics of broad antibacterial spectrum, strong antibacterial activity and stability to lactamase. It is effective against many Gram-positive cocci, including Staphylococcus and Enterococcus; it is also effective against Gram-negative bacilli and anaerobic bacteria, and has good antibacterial activity against Pseudomonas aeruginosa, similar to cefoperazone. This product is suitable for sensitive Gram-negative and positive bacteria such as Escherichia coli, Proteus, Klebsiella pneum...
