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] It was patented in 1977 and approved for medical use in 1986. [2]
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.
Ceftolozane–tazobactam is available as a 2:1 fixed combination (such that a 1.5 g dose of ceftolozane–tazobactam is composed of 1 g of ceftolozane and 500 mg of tazobactam). [17] Ceftolozane-tazobactam is administered intravenously.
Cefixime, sold under the brand name Suprax among others, is an antibiotic medication used to treat a number of bacterial infections. [5] These infections include otitis media, strep throat, pneumonia, urinary tract infections, gonorrhea, and Lyme disease. [5]
Participants received either sulbactam/durlobactam or colistin (a comparator antibiotic) for up to 14 days. [2] Both treatment arms also received an additional antibiotic, imipenem/cilastatin , as background therapy for potential hospital-acquired bacterial pneumonia/ventilator-associated bacterial pneumonia pathogens other than Acinetobacter ...
Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates (tazobactam and sulbactam) which ultimately leads to the degradation of the beta-lactamase. [7] Avibactam on the other hand does not contain a beta-lactam ring (non beta-lactam beta-lactamase inhibitor), and instead binds reversibly .
In addition to combining one antibiotic with another, antibiotics are sometimes co-administered with resistance-modifying agents. For example, β-lactam antibiotics may be used in combination with β-lactamase inhibitors, such as clavulanic acid or sulbactam, when a patient is infected with a β-lactamase-producing strain of bacteria.
