Could a simple antibiotic pill after surgery save diabetic patients from infection?
NCT ID NCT07561541
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether taking an antibiotic pill for 7 days after surgery to fix a broken leg, ankle, or foot can lower the chance of wound infection in adults with poorly controlled diabetes. About 40 participants will either receive the antibiotic or standard care (no extra antibiotics). Researchers will track infections and side effects for 90 days after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cefadroxil (or Clindamycin or Bactrim DS as alternatives)
- What this could lead to
- If it works, this could point toward a simple way to prevent wound infections after fracture surgery in people with diabetes.
- What could go wrong
- This is a small pilot study with only 40 participants, so results may not apply broadly. Antibiotics can cause side effects like stomach upset or allergic reactions.
