Efficacy and Tolerability of Suprep With and Without Simethicone for Routine Colonoscopy for Colorectal Cancer Screening

Patients will be randomized to receive either simethicone or placebo in addition to oral sodium sulfate/potassium sulfate/magnesium sulfate solution (Suprep), and will be blinded to whether they are in the simethicone arm or the placebo arm of the trial. Simethicone and placebo will be prepared as identically-appearing liquid solution (2.4 mL) with the assistance of a pharmacist. The simethicone or placebo solution will then be assigned to patients according to the randomization scheme and samples will be labeled with patient information prior to distribution. Only the pharmacist will participate in the labeling process and know which patients receive simethicone or placebo; administering staff, nurses, physicians, and patients will be blinded to this.
