Cefoperazone is a third generation cephalosporin antibiotic, It is one of few cephalosporin antibiotics effective in treating Pseudomonas bacterial infections which are otherwise resistant to these antibiotics. Cefina-SB is a combination of sulbactam and cefoperazone. 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. In some countries, the combination is sold as Sulperazone. Gepach International markets this combination of Cefoperazone with Sulbactam under the brand name Bacperazone. Cefoperazone has a broad spectrum of activity and has been used to target bacteria responsible for causing infections of the respiratory and urinary tract, skin, and the female genital tract.
