  • Sodium Picosulfate, Magnesium Oxide and Anhydrous Citric Acid Oral Solution (Drug): Supplied as two 160 mL ready-to-drink bottles, per subject, without further reconstitution, before administration.
  • Sodium Picosulfate, Magnesium Oxide and Anhydrous Citric Powder (Drug), also known as PREPOPIK®, PicoPrep®: Supplied as two sachets per subject. Subjects will be instructed to reconstitute the medication by combining the contents of one packet with approximately five (5) ounces of cold water and stirring for two to three minutes.

+Outcome measures

Primary outcomes

  • Percentage of Subjects Classified as a Responder Defined by "Excellent" or "Good" [During colonoscopy procedure (5-9 hours after completed treatment)]: The efficacy of overall colon cleansing in terms of responders was measured by a blinded endoscopist using the Modified Aronchick Scale. Modified Aronchick scale is a 4-point scale that grades colon cleansing as Excellent (>90% of mucosa seen, mostly liquid stool, minimal suctioning needed for adequate visualization), Good (>90% of mucosa seen, mostly liquid stool, significant suctioning needed for adequate visualization), Fair (>90% of mucosa seen, mixture of liquid and semisolid stool, could be suctioned and/or washed) or Inadequate (<90% of mucosa seen, mixture of semisolid and solid stool which could not be suctioned or washed).The participant is considered to be a responder if overall colon cleansing is "excellent" or "good" on this 4-point scale.

Secondary outcomes

  • Percentage of Subjects Classified as a Responder Defined by a Score ≥2 in the Right Segment of the Colon [During colonoscopy procedure (5-9 hours after completed treatment)]: The percentage of subjects classified as responders, defined by a Boston Bowel Preparation Scale (BBPS) score ≥2 in the right segment of the colon was determined. The BBPS scale: 0= Unprepared colon segment with mucosa not seen due to solid stool that cannot be cleared; 1= Portion of mucosa of the colon segment seen, but other areas of the colon segment not well seen due to staining, residual stool, and/or opaque liquid; 2= Minor amount of residual staining, small fragments of stool and/or opaque liquid, but mucosa of colon segment seen well; 3= Entire mucosa of colon segment seen well with no residual staining, small fragments of stool or opaque liquid.
  • Percentage of Subjects Classified as a Responder Defined by a Score ≥2 in the Transverse Segment of the Colon [During colonoscopy procedure (5-9 hours after completed treatment)]: The percentage of subjects classified as responders, defined by a Boston Bowel Preparation Scale (BBPS) score ≥2 in the transverse segment of the colon was determined. The BBPS scale: 0= Unprepared colon segment with mucosa not seen due to solid stool that cannot be cleared; 1= Portion of mucosa of the colon segment seen, but other areas of the colon segment not well seen due to staining, residual stool, and/or opaque liquid; 2= Minor amount of residual staining, small fragments of stool and/or opaque liquid, but mucosa of colon segment seen well; 3= Entire mucosa of colon segment seen well with no residual staining, small fragments of stool or opaque liquid.
  • Percentage of Subjects Classified as a Responder Defined by a Score ≥2 in the Left Segment of the Colon [During colonoscopy procedure (5-9 hours after completed treatment)]: The percentage of subjects classified as responders, defined by a Boston Bowel Preparation Scale (BBPS) score ≥2 in the left segment of the colon was determined. The BBPS scale: 0= Unprepared colon segment with mucosa not seen due to solid stool that cannot be cleared; 1= Portion of mucosa of the colon segment seen, but other areas of the colon segment not well seen due to staining, residual stool, and/or opaque liquid; 2= Minor amount of residual staining, small fragments of stool and/or opaque liquid, but mucosa of colon segment seen well; 3= Entire mucosa of colon segment seen well with no residual staining, small fragments of stool or opaque liquid.
