Estimated Study Completion Date : December 2017

Arm Intervention/treatment
Active Comparator: PEG
polyethylene glycol solution 2 liters
Drug: polyethylene glycole (PEG) solution
Active Comparator: NapP
Sodium picosulphate and magnesium citrate solution 300 ml
Drug: sodium picosulphate and magnesium citrate solution

Primary Outcome Measures :
  1. Boston Bowel Preparation Scale value [ Time Frame: at time of colonscopy ]
    evaluated by two endoscopists who are blinded to treatment assigned at randomization

  2. patient reported acceptability score [ Time Frame: just prior to colonscopy ]
    using visual analog scale

Secondary Outcome Measures :
  1. percent of bowel cleansing regimen dose assumed as reported by patient [ Time Frame: just prior to colonoscopy ]
