The sodium content is approximately 137 mg (approximately 6.0 mEq). Each vial of INVANZ contains the following inactive ingredients: 175 mg sodium bicarbonate and sodium hydroxide to adjust pH to 7.5.
Is ertapenem and meropenem 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.
Similarly, Does ertapenem cover Serratia? Ertapenem has a broad antibacterial spectrum with MIC90 values < 0.5 mg/l for penicillin-susceptible Streptococcus pneumoniae, Streptococcus pyogenes, methicillin-sensitive Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli, Citrobacter spp., Klebsiella spp., Serratia spp., Proteus …
Is Proteus mirabilis sensitive to ertapenem?
mirabilis. These results support the potent in vitro bactericidal activity of ertapenem against all multiresistant strains selected in this study and the use of this drug in the treatment of intra-abdominal infections.
Does ertapenem cover Pseudomonas?
Compared with imipenem, meropenem and doripenem, the spectrum of activity of ertapenem is more limited primarily because it lacks activity against Pseudomonas aeruginosa and Enterococcus spp.
Is ertapenem stronger than meropenem?
In general for these target pathogens, based on MIC90 values, ertapenem has similar potency to meropenem and is slightly more potent than imipenem against Gram-negative pathogens whereas imipenem is slightly more potent against Gram-positive pathogens.
What makes ertapenem different from other carbapenems? This in vitro data suggest that ertapenem is less stable than the other carbapenems to the beta-lactamase enzymes and may confer resistance more rapidly in vivo. P. aeruginosa has become resistant to many of the beta-lactam antibiotics. It remains fairly sensitive to the carbapenems, excluding ertapenem.
What does meropenem cover that ertapenem does not? Compared with imipenem, meropenem and doripenem, the spectrum of activity of ertapenem is more limited primarily because it lacks activity against Pseudomonas aeruginosa and Enterococcus spp.
Does ertapenem cover enterococcus?
Piperacillin activity is similar to that of penicillin, and imipenem generally is active against penicillin-susceptible E. faecalis. Cell wall-active agents with limited or no activity against enterococci include nafcillin, oxacillin, ticarcillin, ertapenem, most cephalosporins, and aztreonam.
Does ertapenem cover Lactobacillus? However, it is not active against Pseudomonas aeruginosa, Acinetobacter spp., Stenotrophomonas maltophilia, Burkholderia cepacia, and Aeromonas spp., entorococci, MRSA, penicillin-resistant Streptococcus pneumoniae, Clostridium difficile and Lactobacillus spp.
Does ertapenem cover group B strep?
Ertapenem is a novel carbapenem reported to have activity against gram-positive bacteria similar to that of meropenem (16, 17). Linezolid, ertapenem, and quinupristin-dalfopristin all proved to be highly active in vitro against all of the GBS isolates tested.
Does ertapenem cover E faecalis? Ertapenem is a broad-spectrum antibiotic with activity against a range of gram-positive, gram-negative, and anaerobic gastrointestinal organisms but with limited activity against E. faecalis [4, 5].
Is ertapenem broad-spectrum?
Spectrum: Like its big brother (Imipenem), ertapenem has a very broad spectrum of activity that includes all anaerobes and many aerobic gram-positive and gram-negative organisms. It has poor activity against P aeruginosa and Acinetobacter and lacks activity against Enterococcus faecium, S. epidermidis, B. Lepacia, S.
Does ertapenem cover Enterobacter?
Geometric mean MICs of ertapenem for the collection were reduced five-fold by clavulanic acid for Klebsiella spp. compared with eight-fold by cloxacillin for Enterobacter spp. This study highlights the fact that ertapenem resistance is being detected in Klebsiella spp. and Enterobacter spp.
Does ertapenem cover E coli? Several in vitro studies have evaluated ertapenem and have shown excellent in vitro susceptibility to ESBL-producing Escherichia coli and Klebsiella pneumoniae with comparable MIC 90 to that of group 2 carbapenems.
What bacteria does ertapenem not cover?
Spectrum: Like its big brother (Imipenem), ertapenem has a very broad spectrum of activity that includes all anaerobes and many aerobic gram-positive and gram-negative organisms. It has poor activity against P aeruginosa and Acinetobacter and lacks activity against Enterococcus faecium, S. epidermidis, B. Lepacia, S.
Does meropenem cover Enterococcus faecium?
Amongst common human pathogens, only methicillin-resistant staphylococci and Enterococcus faecium are uniformly resistant to meropenem. The meropenem MICs for penicillin-resistant Streptococcus pneumoniae are higher than for penicillin-susceptible strains but the organisms remain susceptible.
How does carbapenem work? Closely related to penicillins, carbapenems are bactericidal beta-lactam antibiotics that bind to penicillin-binding proteins (PBPs). By binding and inactivating these proteins, carbapenems inhibit the synthesis of the bacterial cell wall, which leads to cell death.
Is ertapenem a beta lactamase inhibitor?
The carbapenems are beta-lactam-type antibiotics with an exceptionally broad spectrum of activity. Ertapenem is a new carbapenem developed to address the pharmacokinetic shortcomings (short half-life) of imipenem and meropenem.
Can ESBL be treated with oral antibiotics? Conclusions: Cefixime and amoxicillin/clavulanate combination therapy could be an effective oral outpatient treatment option for ESBL-EC. In vitro synergistic testing is simple and predictive of successful treatment.
What ertapenem does not cover?
Ertapenem does NOT cover Pseudomonas, but does still cover ESBL (main advantage is convenient once/day dosing – great outpatient IV drug). Other differences of Ertapenem (vs other carbapenems) is lack of activity vs Acinetobacter and Enterococci.
What is agar well diffusion method? Agar well diffusion method is widely used to evaluate the antimicrobial activity of plants or microbial extracts [32], [33]. Similarly to the procedure used in disk-diffusion method, the agar plate surface is inoculated by spreading a volume of the microbial inoculum over the entire agar surface.
What is MRS broth?
MRS Broth is a medium for the cultivation and enumeration of Lactobacillus spp. This product has the same formulation as LAB093 MRS Agar with the omission of agar. Originally developed in 1960 by de Man, Rogosa & Sharpe, the medium can be used for confirmatory tests on organisms isolated on MRS Agar.
Is ertapenem broad spectrum? Spectrum: Like its big brother (Imipenem), ertapenem has a very broad spectrum of activity that includes all anaerobes and many aerobic gram-positive and gram-negative organisms. It has poor activity against P aeruginosa and Acinetobacter and lacks activity against Enterococcus faecium, S. epidermidis, B. Lepacia, S.
