Pharmacokinetic/pharmacodynamic analysis of meropenem and fosfomycin combinations in in vitro time-kill and hollow-fibre infection models against multidrug-resistant and carbapenemase-producing Klebsiella pneumoniae.
J Antimicrob Chemother
December 2024
Department of Clinical Pharmacy, Institute of Pharmacy, University of Hamburg, Hamburg, Germany.
Background: MDR Gram-negative bacteria, such as ESBL-producing and carbapenemase-producing Klebsiella pneumoniae, represent major global health threats. Treatment options are limited due to increasing resistance and slowed development of novel antimicrobials, making it necessary to apply effective combination therapies based on approved antibiotics.
Objectives: To quantitatively evaluate the synergistic potential of meropenem and fosfomycin against carbapenem-resistant K.
Pharmacokinetic/pharmacodynamic analysis of sulbactam against pneumonia: establishing efficacy targets in the epithelial lining fluid.
JAC Antimicrob Resist

Center for Anti-Infective Research and Development, Hartford Hospital, Hartford, CT, USA.
Background: Sulbactam is an effective therapy for infections. Previous sulbactam pharmacokinetics/pharmacodynamics (PK/PD) analyses established exposure efficacy targets in plasma against pneumonia. Herein, we established sulbactam efficacy targets in epithelial lining fluid (ELF).

Facultés de Médecine et de Pharmacie de Lyon, Univ Lyon, Université Claude Bernard Lyon 1, Lyon, France.
Background And Objectives: Cefiderocol approved dosages are based on a prolonged infusion (PI) of 3 h that may not be adequate in all settings The objective of this study was to identify alternative cefiderocol dosage regimens based on short infusion (SI) or continuous infusion (CI).
Methods: We performed 1000-patient pharmacokinetic/pharmacodynamic (PK/PD) simulations based on a reference population model. Drug penetration into the epithelial lining fluid (ELF) was considered for pneumonia.
Safety, Tolerability and Pharmacokinetic-Pharmacodynamic Relationship of NX210c Peptide in Healthy Elderly Volunteers: Randomized, Placebo-Controlled, Double-Blind, Multiple Ascending Dose Study.

Introduction: Blood-brain barrier (BBB) integrity is fundamental to brain homeostasis, enabling control of substance exchange and safeguarding neurons against harmful toxins, pathogens, and immune cells that lead to dysregulation and inflammation involved in ageing and neurodegenerative diseases (NDD). The cyclized peptide NX210c is a thrombospondin type 1 repeat analogue derived from subcommissural organ-spondin. It exerts beneficial effects in animal models of NDD owing to its effects on neurons and endothelial cells.

NH600001 is a new general anaesthetic drug with a structure similar to etomidate. The objective of this study was to investigate the relationship between concentrations of NH600001 and sedation efficacy based on data from phase I-II studies and factors influencing the pharmacokinetics and pharmacodynamics of NH600001. The dataset consisted of 2 phase I studies in healthy subjects and 1 phase II study in patients undergoing gastroscopy.
