Meropenem, sold under the brand name Merrem among others, is an intravenous carbapenem antibiotic used to treat a variety of bacterial infections. [3] Some of these include meningitis, intra-abdominal infection, pneumonia, sepsis, and anthrax.
The carbapenems imipenem and meropenem are recommended by the American Thoracic Society and the Infectious Disease Society of America as one of several first-line therapy options for people with late-onset hospital-acquired or ventilator-associated pneumonia, especially when Pseudomonas, Acinetobacter, or extended spectrum beta-lactamase ...
Infections caused by Gram-negative bacteria, such as Escherichia coli and Klebsiella particularly Pseudomonas aeruginosa. Effective against aerobic bacteria (not obligate/facultative anaerobes) and tularemia. All aminoglycosides are ineffective when taken orally as the stomach will digest the drug before it goes into the bloodstream.
These bacteria pose a great threat to public health due to the limited treatment options available as well as lack of newly developed antimicrobial medications. MDR strains of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii have become of most concern because they have been reported by hospitals all around the United ...
The activity of meropenem/vaborbactam against P. aeruginosa and A. baumannii was found to be similar to that of meropenem alone. In fact, in these species, meropenem resistance is largely mediated by mechanisms that are not antagonized by vaborbactam (e.g., outer-membrane impermeability, upregulation of efflux systems, and production of class B ...
Treatment of P. aeruginosa infections can be difficult due to its natural resistance to antibiotics. When more advanced antibiotic drug regimens are needed adverse effects may result. It is citrate, catalase, and oxidase positive. It is found in soil, water, skin flora, and most human-made environments throughout the world.

The drug is not effective against Pseudomonas aeruginosa, Morganella morganii, or Providencia stuartii, nor against AmpC β-lactamase- and ESBL-producing Gram-negative bacteria or carbapenem-resistant Enterobacteriaceae (CRE). [15] It is not recommended in the empiric treatment of acute pyelonephritis or hospital-acquired UTIs. [15]
