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.
The spectrum of action includes many Gram-positive and Gram-negative bacteria (including Pseudomonas) and anaerobic bacteria. The overall spectrum is similar to that of imipenem, although meropenem is more active against Enterobacteriaceae and less active against Gram-positive bacteria. Meropenem is effective against bacteria producing extended ...
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] It was patented in 1977 and approved for medical use in 1986. [2]
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.
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.
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]
