Examining the Effect of Ondansetron on Bowel Prep Success

Study Purpose

This is a pilot randomized-controlled trial assessing the utility of ondansetron for improving pediatric pre-colonoscopy bowel prep outcomes using the boston bowel preparation score, as well as assessing the impact on patient experience of bowel preparation.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	2 Years - 20 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Age >2, <20.

- clinically indicated for a colonoscopy.

Exclusion Criteria:

- known arrhythmia or long QT

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05439772
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 4

Additional Details

The study will compare two approaches to pre-colonoscopy cleanout, one with traditional laxatives only, and one with laxatives + anti-emetic therapy. The medication to be added will be Ondansetron (brand name: Zofran). Classically, the bowel prep entails drinking large amounts of water with an osmotic laxative and being only on a liquid diet the day prior to the procedure. Drinking this mixture of water with an osmotic laxative may cause nausea and discomfort in some patients that may prevent them from finishing the bowel prep. This will therefore affect the visualization of the colon during the procedure, as there will still be retained, hard stool. Having large amounts of stool in the colon during the procedure can make the colonoscopy more difficult, takes a longer time to complete, can make the study inconclusive, unable to properly diagnose, and difficult to take biopsies. This study assesses the impact of anti-emetic medication (ondansetron) on the bowel prep experience with the goal of improving participant tolerance and preparation success. This will eliminate concern for retained stool and less chance of cancelling a procedure due to improper bowel prep.

Arms & Interventions

Arms

No Intervention: Control

Pediatric patients between the ages of 2-20 who have a clinical indication for colonoscopy, who will undergo standard colonoscopy preparation of polyethylene glycol and bisacodyl

Experimental: Ondansetron

Pediatric patients between the ages of 2-20 who have a clinical indication for colonoscopy, who will undergo standard colonoscopy preparation of polyethylene glycol and bisacodyl with the addition of one dose of ondansetron prior to initiating bowel preparation.

Interventions

Drug: - Ondansetron

Patient will take one dissolvable tablet of ondansetron prior to initiating PEG consumption.
