First seen May 08, 2026 · Last updated May 08, 2026

Summary

This study compares two oral bowel-cleansing agents, lactulose and sodium phosphate, to see which one works better and is easier for patients before a colonoscopy. About 300 adults scheduled for a colonoscopy will take one of the two preparations. The goal is to find which option provides a cleaner colon, causes fewer side effects like nausea, and is more comfortable for the patient.
