What this trial studies

This observational study aims to assess the pharmacokinetics and pharmacodynamics of several antibiotics in patients undergoing renal replacement therapy (RRT). It will involve 180-240 adult patients receiving intravenous antibiotics while on RRT, with blood and fluid samples collected to analyze drug concentrations. The study will help determine the appropriate dosing of these antibiotics to ensure effective treatment. Data will be modeled to predict future dosing requirements based on the RRT modality used.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 who are prescribed specific antibiotics while receiving renal replacement therapy.

Not a fit: Patients under 18, pregnant women, or those with certain health conditions like severe anemia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to optimized antibiotic dosing for patients undergoing renal replacement therapy, improving treatment outcomes.

How similar studies have performed: While pharmacokinetic studies in similar contexts exist, this specific evaluation of multiple antibiotics in RRT patients is relatively novel.
