Two bowel prep methods before colonoscopy study
Part of Digestive system clinical trials.
This trial compares two ways to clean the bowel before a colonoscopy: a 4-liter split-dose of a laxative plus two other medications versus a 2-liter split-dose with a gas-relief medication. The goal is to see which works better and is easier to tolerate.

This trial compares different ways to prepare your bowel on the same day as a colonoscopy. The goal is to find which method is easiest to complete and best cleans the colon, which can help make the procedure more effective.
This trial compares two different bowel preparation solutions (2L-PEG and oral sulfate solution) for people with Crohn's disease or ulcerative colitis who are having a colonoscopy. The goal is to find which preparation works better and is more comfortable for patients with these conditions.
This trial looks at whether using electrolyte drinks instead of water to mix your colonoscopy prep medicine (sodium phosphate or polyethylene glycol) makes the prep easier or more effective. It may help you feel less bloated or nauseated during bowel preparation.
This trial compares two laxatives, prucalopride and bisacodyl, to see which works better at cleaning the colon before a colonoscopy. If you are scheduled for a colonoscopy, you may be able to join and help find the best preparation method.
This study tests whether combining an electrolyte beverage (a drink with salts and minerals) with polyethylene glycol—a standard bowel-cleaning solution—helps prepare your colon better for colonoscopy. The goal is to see if this combination makes the preparation easier to tolerate while still cleaning your bowel effectively.
This study looks at what factors might make it harder to clean out your bowel before a colonoscopy. Understanding these reasons could help doctors give better instructions and improve success rates.
