In order to analyze the effectiveness and patient tolerance of the two bowel preparation
regimens, we will compare Polyethylene Glycol Electrolytes Powder (PEG-4000) and Mizone with
PEG-ELS. The aim was to demonstrate that polyethylene glycol electrolyte powder (PEG-4000)
and Mizone is not inferior in overall quality of intestinal preparation to PEG-ELS in
subjects undergoing colonoscopy.
