• Routinely accepted indication for undergoing colonoscopy, including but not limited to polyposis coli diagnosis or surveillance, gastrointestinal bleeding, unexplained diarrhoea or constipation, surveillance of inflammatory bowel disease or confirmation of mucosal healing, abdominal pain, abnormal endosonography or manometry, anaemia of unknown aetiology, cancer surveillance

• In the investigator's judgment, the parent(s)/legal representative are/is mentally competent to provide informed consent for the subject to participate in the study

• In the investigator's judgement, subject is able and willing to follow study procedures including drug administration and response to questionnaires

Exclusion Criteria:

• Subject with bowel perforation or increased risk of bowel perforation, including connective tissue disorders or recent bowel surgery

• Subject with previous significant gastrointestinal surgery (e.g. colostomy, colectomy, gastric bypass, stomach stapling)

• Subject with uncontrolled pre-existing electrolyte abnormalities, or with electrolyte abnormalities based on Visit 1 laboratory results such as hypernatremia, hyponatremia, hyperphosphatemia, hypokalaemia, hypocalcaemia, uncorrected dehydration, or secondary to the use of medications such as diuretics or angiotensin converting enzyme inhibitors judged clinically significant by the investigator

• Subject with a prior history or current condition of severe renal (estimated glomerular filtration rate (GFR) less than 30 mL/min/1.73 m^2 as calculated by using the Schwartz bedside equation* [Schwartz et al, 2009]**), liver (ascites, Child-Pugh C), cardiac insufficiency (including congestive heart failure all grades) or hyperuricemia

*The estimated GFR will be calculated in patients with elevated creatinine at baseline
