Summary

This study tests whether spraying a powder made of tranexamic acid and sucralfate onto bleeding sites in the colon can lower the chance of rebleeding after standard treatment. About 60 people hospitalized for lower GI bleeding will take part. All receive usual care, and half also get the powder spray. Researchers will track rebleeding over 28 days.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
tranexamic acid and sucralfate powder spray
What this could lead to
If effective, this simple powder spray could become a standard add-on to reduce rebleeding after colonoscopy for lower GI bleeding.
What could go wrong
This is a small pilot study, so results may not apply broadly. The powder could cause allergic reactions or other complications.
