BACKGROUND Suspected or complicated intra-abdominal infections are common in young infants and lead to significant morbidity and mortality. Meropenem is a broad-spectrum antimicrobial agent with excellent activity against pathogens associated with intra-abdominal infections in this population. The purpose of this study was to determine the pharmacokinetics (PK) of meropenem in young infants as ...

BACKGROUND The purpose of this study was to examine the removal of meropenem during an 8-h sustained low-efficiency dialysis (SLED) session. Using a minimum inhibitory concentration (MIC) = 2 microg/mL as our reference point, we also evaluated the therapeutic adequacy of dosing meropenem as 1 g every 12 h during SLED. METHODS This was a prospective, open-label study involving 10 intensive car...

Klebsiella pneumoniae carbapenemase (KPC)-producing isolates have become increasingly prevalent worldwide, and these organisms are often multidrug resistant, limiting the therapeutic options available for treating infections. We evaluated the activity of meropenem combined with the serine β-lactamase inhibitor vaborbactam (formerly RPX7009) against 315 serine carbapenemase-producing Enterobacte...

BACKGROUND The antibiotic meropenem is commonly administered in patients with severe sepsis and septic shock. We compared the pharmacokinetic, clinical, and bacteriological efficacies of continuous infusion of meropenem versus intermittent administration in such patients. METHODS Patients admitted to the Intensive Care Unit (ICU) with severe sepsis or septic shock who received meropenem were ...

Objectives; Tomopenem (CS-023) is a novel parenteral carbapenem with broad spectrum activity against Gram-positive and -negative bacteria, as well as potent activity against drug resistant pathogens, including penicillin-resistant Streptococcus pneumoniae, methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa. We compared the in vivo activity of tomopenem and that of meropenem ...

Pathophysiological changes during the early phase of severe sepsis and septic shock in critically ill patients, resulting in altered pharmacokinetic (PK) patterns for antibiotics, are important factors influencing therapeutic success. The aims of this study were (i) to reveal the population PK parameters and (ii) to assess the probability of target attainment (PTA) for meropenem. The PK studies...

We investigated the in vitro susceptibilities of 23 Propionibacterium acnes ophthalmic isolates to ertapenem, meropenem, and cefepime by utilizing the Etest. The MICs ranged from 0.094 microg/ml to 0.75 microg/ml, 0.094 microg/ml to 1.5 microg/ml, and 1 microg/ml to 12 microg/ml for ertapenem, meropenem, and cefepime, respectively. Based on our excellent in vitro carbapenem susceptibility resul...

A sensitive and selective liquid chromatography tandem mass spectrometry (LC–MS/MS) method for determination of meropenem in rabbit plasma was developed. After addition of triazolam as internal standard (IS), protein precipitation by acetonitrile was used in sample preparation. Chromatographic separation was achieved on a Restek Allure (TM) PFP Propyl (2.1 mm × 100 mm, 5 μm) column with acetoni...

BACKGROUND Ventriculitis is a complication of temporary intraventricular drains. The limited penetration of meropenem into the cerebrospinal fluid (CSF) is well known. However, ventricular CSF pharmacokinetic data in patients with ventriculitis are lacking. The aim of this study was to evaluate meropenem pharmacokinetics in the serum and CSF of neurocritical care patients with proven or suspect...
