New colonoscopy prep powder could mean less laxative, same clean results
NCT ID NCT06514989
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tested whether a low-residue nutrition formula powder, taken with a smaller amount of laxative (2 liters), works as well as a standard low-residue diet with more laxative (3 liters) for cleaning the bowel before a colonoscopy. About 757 adults scheduled for colonoscopy took part. The goal was to see if the new approach causes fewer side effects like bloating or nausea while still providing a clear view for the doctor.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
low-residue full nutrition formula powder
What this could lead to
If it works, this could make bowel preparation for colonoscopy more tolerable by reducing the amount of laxative needed.
What could go wrong
This is a completed study, but it only compares two preparation methods; the new formula may not clean the bowel as well as the standard approach, and results may not apply to everyone.
