It is hypothesized that PEG 2L with citrate and simeticone plus bisacodyl will have similar bowel cleansing efficacy versus PEG 2L with ascorbate. Safety, tolerability, acceptance and compliance of the two reduced volume PEG-based bowel preparation will be also compared.

Condition Intervention Phase
Drug: 2L PEG-CS plus bisacodyl
Drug: 2L PEG-ASC
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Low Volume Bowel Preparation for Colonoscopy: a Comparison Between PEG-CS Plus Bisacodyl Versus PEG-ASC

Further study details as provided by Promefarm S.r.l.:

Primary Outcome Measures:
  • Evaluation of the quality of bowel preparation by BBPS [ Time Frame: 20 minutes ]
    BBPS is an established rating scale to evaluate the quality of bowel preparation. A score greater than 6 is considered as success. The rate of success will be compared between the two groups.

Secondary Outcome Measures:
  • Difference in mucosal visibility between the two groups [ Time Frame: 20 minutes ]
    Three point rating scale(0-2).

  • Number of patients with adverse events [ Time Frame: 24 hours ]
    Patient questioning.

  • Difference in tolerability between the two groups [ Time Frame: 24 hours ]
    Difference in the percentage of patients in the two groups who developed GI symptoms related to bowel preparation.

  • Difference in patients acceptability between the two groups [ Time Frame: 24 hours ]
    Difference in the percentage of patients in the two groups who were willing to repeat the preparation and easy to take the bowel preparation.

  • Difference in patients compliance between the two groups [ Time Frame: 24 hours ]
    Difference in the percentage of patients who took at least 75% of bowel preparation.
