Abstract

PURPOSE: To provide the title composition containing a specific cephalosporin compound and a β-lactamase-inhibiting substance CP-45899, and effective even to resistant bacteria.
CONSTITUTION: A composition containing (A) (2S,5R),3,3-dimethyl-7-oxo-4-thia- 1-azacylo[3,2,0]heptane-2-carboxylic acid 4,4-dioxide (CP-45899) or its salt which are β-lactamase-inhibiting substances, of formula I, and (B) a compound of formula II (R1 is H or OH; R2 is H, OH, halogen, or lower alkyl) or its salt. The weight ratio of (A) to (B) is 1W15-1. Although the compound (B) has only poor activity to cephalosporinase, the combination of the compound (B) to the compound (A) gives a composition which is effective even to gram negative bacterial including resistant bacteria.
