Cefepime is a fourth-generation cephalosporin antibiotic. Cefepime has an extended spectrum of activity against Gram-positive and Gram-negative bacteria , with greater activity against both types of organism than third-generation agents.
Ceftazidime, sold under the brand name Fortaz among others, is a third-generation cephalosporin antibiotic useful for the treatment of a number of bacterial infections. [1] [5] Specifically it is used for joint infections, meningitis, pneumonia, sepsis, urinary tract infections, malignant otitis externa, Pseudomonas aeruginosa infection, and vibrio infection. [1]
Cefepime/enmetazobactam, sold under the brand name Exblifep, is a medication used for the treatment of urinary tract infections. [ 1 ] [ 2 ] It is a fixed dose combination containing cefepime , a cephalosporin antibacterial; and enmetazobactam , a beta-lactamase inhibitor .
Cefepime: Maxipime: Covers pseudomonal infections. Gastrointestinal upset and diarrhea; Nausea (if alcohol taken concurrently) Allergic reactions; Same mode of action as other beta-lactam antibiotics: disrupt the synthesis of the peptidoglycan layer of bacterial cell walls. Cephalosporins (Fifth generation) Ceftaroline fosamil: Teflaro: Used to ...
[10] [12] The British National Formulary previously issued blanket warnings of 10% cross-reactivity, but, since the September 2008 edition, suggests, in the absence of suitable alternatives, oral cefixime or cefuroxime and injectable cefotaxime, ceftazidime, and ceftriaxone can be used with caution, but the use of cefaclor, cefadroxil ...

Enmetazobactam, usually combined with cefepime ; β-lactamase inhibitors with a diazabicyclooctane core: Avibactam, approved in combination with ceftazidime (Avycaz, Zavicefta), currently undergoing clinical trials for combination with ceftaroline
The antibacterial spectrum of ceftazidime/avibactam includes nearly all Enterobacteriaceae, including ceftazidime-resistant strains. The activity of ceftazidime/avibactam against the important hospital pathogen Pseudomonas aeruginosa is variable, due to the potential presence of other resistance mechanisms in addition to β-lactamase production.
