What is "cefoperazone"

n. A cephalosporin antibiotic.

n. a parenteral cephalosporin (trade name Cefobid) used for severe infections [syn: Cefobid]

Cefoperazone is a third-generation cephalosporin antibiotic, marketed by Pfizer under the name Cefobid. It is one of few cephalosporin antibiotics effective in treating Pseudomonas bacterial infections which are otherwise resistant to these antibiotics.

Cefoperazone is also sold as a co-formulation with sulbactam. Cefoperazone exerts its bactericidal effect by inhibiting the bacterial cell wall synthesis, and sulbactam acts as a beta-lactamase inhibitor, to increase the antibacterial activity of cefoperazone against beta-lactamase-producing organisms.
