A Study Comparing PEG-3350 (Miralax) and Gatorade With PEG-ELS (Golytely) for Bowel Preparation Prior to Colonoscopy

Overview

The purpose of this study to to see how well Miralax (PEG-3350) and Gatorade cleans the colon before a colonoscopy and how easy it is to take compared to Golytely (PEG-ELS) bowel preparation solution. Another purpose is to see if taking half of the bowel preparation solution on the evening before the colonoscopy and half on the morning of the colonoscopy will result in a cleaner colon than taking all of the bowel preparation solution on the evening before.
