Can High-Dose amoxicillin be made safer?
NCT ID NCT04070469
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This study looks at patients receiving high-dose intravenous amoxicillin for serious bacterial infections. Researchers will measure drug levels in the blood during the first week to see how much they vary between patients and within the same patient. They will also check for side effects like kidney problems (crystalluria) and aim to identify factors linked to overdose. The goal is to gather information that could lead to safer, more personalized dosing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- amoxicillin
- What this could lead to
- If successful, this could help define safer dosing targets for high-dose amoxicillin, reducing kidney and neurological side effects in serious infections.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly test a new therapy. Results may not lead to immediate practice changes, and individual responses vary widely.
