Problems solved by technology

The concentration of 2 μg / ml has strong inhibitory effect on Richmond-Syks Ⅱ, Ⅲ, Ⅳ and Ⅴ type β-lactamase, but has no effect on type I β-lactamase
[0007] The storage stability of sulbactam sodium in the prior art is relatively poor, and its related substances will increase significantly in light and humid environments, and its pharmaceutical composition with mezlocillin sodium is stored for a long time, and the impurity content is relatively high. Poor safety, in order to obtain a pharmaceutical composition of mezlocillin sodium and sulbactam sodium with better performance, the present invention is proposed
