Description

Ceftazidime impurity B is a ceftazidime impurity that is found in the drug Ceftazidime. Ceftazidime is an antibiotic that belongs to the group of cephalosporin antibiotics and inhibits bacterial growth by inhibiting cell wall synthesis. Ceftazidime impurity B has been shown to be toxic to gram-positive bacteria, such as Enterococcus faecium and Staphylococcus aureus, but not to gram-negative bacteria, such as Escherichia coli. In addition, it has been shown to have no effect on the IL-2 receptor of T cells or the binding of penicillin-binding protein. It has also been shown to be safe for injection into mice and rats in toxicity studies.
