Cefoperazone/sulbactam is a combination drug used as an antibiotic. It is effective for the treatment of urinary tract infections . [ 2 ] It contains cefoperazone , a β-lactam antibiotic , and sulbactam , a β-lactamase inhibitor , which helps prevent bacteria from breaking down cefoperazone.
Sulbactam is a β-lactamase inhibitor. This drug is given in combination with β-lactam antibiotics to inhibit β-lactamase , an enzyme produced by bacteria that destroys the antibiotics . [ 1 ]
Cefoperazone contains an N-methylthiotetrazole (NMTT or 1-MTT) side chain.As the antibiotic is broken down in the body, it releases free NMTT, which can cause hypoprothrombinemia (likely due to inhibition of the enzyme vitamin K epoxide reductase) and a reaction with ethanol similar to that produced by disulfiram (Antabuse effect), due to inhibition of aldehyde dehydrogenase.
Cefoperazone [Unlike most third-generation agents, cefoperazone is active against Pseudomonas aeruginosa], combination Cefoperazone with Sulbactam makes more effective antibiotic, because Sulbactam avoid degeneration of Cefoperazone: Cefobid (discontinued) Cefotaxime: Claforan: Cefpodoxime: Vantin, Banadoz
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
Ceftolozane exerts bactericidal activities against susceptible gram-negative and gram-positive infections by inhibiting essential penicillin-binding proteins (PBPs), which are required for peptidoglycan cross-linking for bacterial cell wall synthesis, resulting in inhibition of cell wall synthesis and subsequent cell death.
[15] [16] These include latamoxef , cefmenoxime, cefoperazone, cefamandole, cefmetazole, and cefotetan. This is thought to be due to the methylthiotetrazole side-chain of these cephalosporins, which blocks the enzyme vitamin K epoxide reductase (likely causing hypothrombinemia) and aldehyde dehydrogenase (causing alcohol intolerance).

The efficacy of sulbactam/durlobactam was established in a multicenter, active-controlled, open-label (investigator-unblinded, assessor-blinded), non-inferiority clinical trial in 177 hospitalized adults with pneumonia caused by carbapenem-resistant A. baumannii. [2]
