Is imipenem and ertapenem the same?

Ertapenem is similar to meropenem and imipenem in its activity against aerobic gram-positive and anaerobic organisms but is less active against non-fermentative Gram-negative bacilli 7, 8.

Does meropenem cover Enterococcus faecalis?

Most Enterococcus faecalis and many Pseudomonas aeruginosa strains, including those resistant to broad-spectrum penicillins and cephalosporins, are susceptible to imipenem, meropenem, and doripenem but are resistant to ertapenem. However, meropenem and doripenem are less active against E. faecalis than imipenem.

Does ertapenem cover Enterococcus?

faecalis. Cell wall-active agents with limited or no activity against enterococci include nafcillin, oxacillin, ticarcillin, ertapenem, most cephalosporins, and aztreonam.

Does ertapenem cover Pseudomonas?

Ertapenem is a group 1 carbapenem with little activity against Pseudomonas and Acinetobacter species. The lack of clinically relevant activity against these microorganisms has raised uncertainties about its selection for mutants with cross-resistance to group 2 carbapenems (imipenem, meropenem and doripenem).

What bacteria does ertapenem not cover?

Spectrum includes gram-negative bacilli, including Enterobacteriaceae. Ertapenem is not as active against Pseudomonas aeruginosa as other carbapenems. It is also active against most gram-positive bacteria, except methicillin-resistant strains of Staphylococcus and Enterococcus.

What bacteria does ertapenem treat?

Ertapenem, a carbapenem antibacterial, has in vitro activity against many Gram- negative (including Enterobacteriaceae) and Gram-positive aerobic and anaerobic bacteria that are commonly associated with various infections.

What is Enterococcus faecalis in urinary tract infection?

Enterococcus faecalis is a gram-positive bacterium that can cause a variety of nosocomial infections of which urinary tract infections are the most common. These infections can be exceptionally difficult to treat because of drug resistance of many E. faecalis isolates.

What is meropenem used to treat?

Meropenem injection is used to treat skin and abdominal (stomach area) infections caused by bacteria and meningitis (infection of the membranes that surround the brain and spinal cord) in adults and children 3 months of age and older. Meropenem injection is in a class of medications called antibiotics.

Can ertapenem cause fatigue?

Feeling very tired or weak. Mood changes. Seizures. Shakiness.

Is ertapenem a strong antibiotic?

Ertapenem is used to prevent and treat a wide variety of bacterial infections. This medication is known as a carbapenem-type antibiotic. It works by stopping the growth of bacteria.

What is not covered by ertapenem?

Can ertapenem be given orally?

Oral administration of 500 mg/kg ertapenem in mice (35-times the dose used in these cases) produced no adverse effects over 7 days in toxicology studies. This combination of retention in the GI tract and bactericidal properties is favorable in agents used to treat the dysbiosis seen in pouchitis.

What are the roles of meropenem and imipenem?

The exact roles for imipenem-relebactam and meropenem-vaborbactam will be defined by efficacy and safety data from further clinical trials. Potential roles in therapy for these agents include the treatment of suspected or documented infections caused by resistant Gram-negative bacilli-producing ESBL, KPC, and/or AmpC β-lactamases.

What kind of antimicrobial activity does ertapenem have?

Similar to imipenem and meropenem, ertapenem has a very broad spectrum of antimicrobial activity, including Gram-positive and Gram-negative aerobic and anaerobic pathogens.12,13 In contrast to imipenem and meropenem, however, ertapenem has limited in vitro activity against Pseudomonas species [e.g.

Are there any resistance to the carbapenem imipenem?

In general, resistance to these carbapenems is rare. Within a healthcare setting, increases in species-specific carbapenem resistance should be monitored and sudden increases investigated to rule out an outbreak of resistant organisms or spurious test results. What Gram-negative organisms are resistant to imipenem and/or meropenem?

What is the break point for meropenem mic50?

Standards Institute (CLSI) guidelines, the breakpoint for susceptibility of the Enterobacteriaceae, P. aeruginosa, and Acinetobacter spp. is ≤ 4 mg/L for both meropenem and imipenem. The results of the internal survey are illustrated below: Imipenem Meropenem MIC50 1 mg/L ≤1 mg/L
