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.
Meropenem usually results in bacterial death through blocking their ability to make a cell wall. [3] It is resistant to breakdown by many kinds of β-lactamase enzymes, produced by bacteria to protect themselves from antibiotics. [4] [5] [6] Meropenem was patented in 1983. [7] It was approved for medical use in the United States in 1996. [3]
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.

Vaborbactam is a boronic acid β-lactamase inhibitor with a high affinity for serine β-lactamases, including Klebsiella pneumoniae carbapenemase (KPC). [5] Vaborbactam inhibits a variety of β-lactamases, exhibiting a 69 nM K i against the KPC-2 carbapenemase and even lower inhibition constants against CTX-M-15 and SHV-12.
Meropenem/vaborbactam, sold under the brand name Vabomere among others, is a combination medication used to treat complicated urinary tract infections, complicated abdominal infections, and hospital-acquired pneumonia. [2] [3] [4] It contains meropenem, a beta-lactam antibiotic; and vaborbactam, a beta-lactamase inhibitor. [4]
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 ]
While the ring closure in penams and cephems is between positions 1 and 4 of the β-lactam and is oxidative, the clavams and carbapenems have their rings closed between positions 1 and 2 of the ring. β-lactam synthetases are responsible for these cyclizations, and the carboxylate of the open-ring substrates is activated by ATP.
