Meropenem/vaborbactam

Meropenem/vaborbactam is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Meropenem/vaborbactam rather than just read about it. In short: Meropenem/vaborbactam, sold under the brand name Vabomere among others, is a combination medication used to treat complicated urinary tract infections, complicated abdominal infections, and hospital-acquired pneumonia. It contains meropenem, a beta-lactam antibiotic; and vaborbactam, a beta-lactamase inhibitor.

Reference excerpt

Meropenem/vaborbactam, sold under the brand name Vabomere among others, is a combination medication used to treat complicated urinary tract infections, complicated abdominal infections, and hospital-acquired pneumonia. It contains meropenem, a beta-lactam antibiotic; and vaborbactam, a beta-lactamase inhibitor. It is given by injection into a vein. Common side effects include headache, inflammation at the site of injection, nausea, diarrhea, liver inflammation, and low blood potassium. Severe side effects may include anaphylaxis, seizures, and Clostridioides difficile-associated diarrhea. It is unclear if use during pregnancy is safe. Meropenem works by blocking the construction of the bacterial cell wall while vaborbactam blocks the breakdown of meropenem by some beta-lactamases. The combination was approved for medical use in the United States in 2017, in the European Union in 2018, and in Canada in December 2024. It is on the World Health Organization's List of Essential Medicines.

Medical uses It is used to treat complicated urinary tract infections, complicated abdominal infections, and hospital-acquired pneumonia.

Side effects The most common adverse reactions were headache, infusion site reactions and diarrhea. Serious risks include allergic reactions and seizures and Meropenem/vaborbactam should not be used in people with severe allergic reactions to penicillins.

Antimicrobial activity Meropenem/vaborbactam retains antimicrobial activity against class A and class C β-lactamase-producing Enterobacterales, especially those producing ESBL, KPC, and AmpC determinants. Meropenem/vaborbactam is also active against strains of Enterobacterales producing other types of class A serine carbapenemases (e.g. SME and NMC-A enzymes). Resistance to meropenem/vaborbactam in KPC-producing Enterobacterales is currently very rare and mostly due to porin inactivation. Meropenem/vaborbactam retains activity also against strains producing KPC mutants that confer resistance to ceftazidime/avibactam (e.g., KPC-8, KPC-31). 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 or class D β-lactamases). No antimicrobial activity has been reported for MBL-producing Gram-negatives and OXA-48-producing Enterobacterales.

History In a study of 545 adults with complicated urinary tract infections, 98 percent of adults treated with meropenem/vaborbactam compared with about 94 percent of adults treated with piperacillin/tazobactam were cured defined as improvement in symptoms and a negative urine culture. About seven days after completing treatment, roughly 77 percent of adults treated with Vabomere compared with about 73 percent of those treated with piperacillin/tazobactam had resolved symptoms and a negative urine culture. In August 2017, the US Food and Drug Administration approved the combination to treat complicated urinary tract infections and pyelonephritis.

Research Successful bacteremia clearance in a child has been reported using a meropenem-vaborbactam dose of 40 mg/kg every 6 hours given over 3 hours. It attained 100% of meropenem serum concentrations above the minimum inhibitory concentration for at least 40% of the dosing interval.

Worked examples

Example 1 — a first encounter with Meropenem/vaborbactam

Start with the simplest possible case. Write down what Meropenem/vaborbactam claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Meropenem/vaborbactam before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Meropenem/vaborbactam ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Meropenem/vaborbactam

In research: Meropenem/vaborbactam appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Meropenem/vaborbactam in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Meropenem/vaborbactam is common in secondary-school and first-year university syllabi. It links to neighbouring topics Beta-lactamase inhibitors, Carbapenem antibiotics, Combination antibiotics, so understanding it makes those chapters shorter.
In everyday life: Look for Meropenem/vaborbactam outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
