Goals: Evaluate patient tolerance and acceptance of a sodium phosphate (NaP) tablet purgative compared with a 4-L polyethylene glycol (PEG) solution.
Background: Characteristics and side effects of bowel purgatives deter patients from undergoing screening colonoscopy. Published data demonstrated comparable bowel cleansing with NaP tablets and a 4-L PEG solution in 2 phase for 3 studies.
