Ratio: |
1:1 |
2:1 |
Synonyms: |
Cefoperazone Sodium Sulbactam Sodium |
|
Characteristics: |
White powder. |
Usage: Cefoperazone Sodium and Sulbactam Sodium Mixure. Because Sulbactam also binds with some penicillin-binding proteins, sensitive strains are also often rendered more susceptible to cefoperazone together with sulbactam than to cefoperazone alone.
