Quantifying combined effects of colistin and ciprofloxacin against Escherichia coli in an in silico pharmacokinetic-pharmacodynamic model.

Co-administering a low dose of colistin (CST) with ciprofloxacin (CIP) may improve the antibacterial effect against resistant Escherichia coli, offering an acceptable benefit-risk balance. This study aimed to quantify the interaction between ciprofloxacin and colistin in an in silico pharmacokinetic-pharmacodynamic model from in vitro static time-kill experiments (using strains with minimum inhibitory concentrations, MIC 0.023-1 mg/L and MIC 0.

The language of antimicrobial and antibiotic resistance is blocking global collective action.

Sustainable access to effective antibiotics is a foundational need for functioning health care that is increasingly threatened by antibiotic resistance. Although resistance has been known as long as antibiotics have been in clinical use, there are still multiple gaps in the global and local responses. One often cited cause for this complacency is the language that is used to describe the problem and its consequences.

A Core Element and Shared Global Responsibility for Pandemic Preparedness and Response.

Securing equitable antibiotic access as an essential component for health system resilience and pandemic preparedness requires a systems perspective. This article discusses key components that need to be coordinated and paired with adequate financing and resources to ensure antibiotic effectiveness as a global public good, which should be central while discussing a new global agreement.
