Linaclotide for Colonoscopy Bowel Prep
Use of Linaclotide as a Single Agent Colonoscopy Bowel Preparation Regimen; A Pilot Trial
University of Florida
10 participants
Dec 1, 2025
INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to learn if drug Linaclotide can be used as a single agent regimen to adequately prepare bowel for colonoscopy. The main question it aims to answer is: Does drug Linaclotide with Gatorade provide adequate bowel preparation for colonoscopy instead of the standard 4 Liters of Polyethylene glycol (PEG)? Participants will: Take one 290mg dose of Linaclotide 36 hours before the procedure and One 290mg dose of Linaclotide 8 hours before the procedure + 2 Liters of Gatorade and a clear liquid diet 24 hours before the procedure. As per standard of care, all patients will be made Nil Per Oral (NPO) starting midnight before the procedure. The colonoscopy report will then be reviewed for Boston Bowel Preparation Score (BBPS) as a marker of bowel preparation quality, insertion time as a marker of procedure difficulty as well as noted pathology and any complications or physician noted comments.

Interventions
We plan to conduct a pilot study to determine the feasibility of a quality bowel preparation with two 290mg doses of Linaclotide (first dose given 36 hours before, and the other 8 hours prior to the procedure) along with 2 Liters of Gatorade (to prevent dehydration) given the day prior to the colonoscopy instead of the current standard 4 liters of PEG regimen. All study participants will be asked to consume a clear liquid diet for 24hours before the procedure.
