A Trial Comparing Bowel Preparation and Patient Tolerability of Miralax Versus Golytely
A Prospective, Randomized Controlled Trial Comparing the Efficacy and Patient Tolerability of MiraLAX (PEG 3350) vs Golytely as Bowel Preparation for Screening Colonoscopy
Prior to colonoscopies, the colon is cleansed using a laxative. Golytely is approved by the FDA for this purpose. Another laxative, called MiraLax, is approved by the FDA to relieve constipation, but it is not approved specifically for preparation for a colonoscopy. Nonetheless, it is commonly used in clinical practice for this purpose, just as is Golytely. The purpose of this study is to compare Golytely and MiraLax in two ways: to see whether one is better tolerated by patients than the other and to see whether one more effectively cleanses the bowel than the other. The investigators' hypothesis is that these 2 bowel preparation methods are equally effective in bowel cleansing, but that patients prefer Miralax to Golytely.

Phase 4
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Health Services Research
  • Drug: Golytely (polyethylene glycol)
    4 L of golytely, in split dosing. If the patient has a morning colonoscopy, they will take 2 L of golytely over 2 hours the morning prior to their procedure and repeat this at 6 pm the night prior to their procedure.
  • Drug: MiraLax (polyethylene glycol 3350)
    238 gm of MiraLax mixed in 64 oz of Gatorade, to be consumed in split dosing the day prior to scheduled colonoscopy.
  • Active Comparator: Golytely
    216 patients at random will provided a prescription for the standard 4 L golytely preparation as the bowel cleanser for their colonoscopy
    Intervention: Drug: Golytely (polyethylene glycol)
  • Experimental: MiraLax
    216 patients will be randomized to take 238 gm of miralax mixed with 64 oz of gatorade for their bowel cleanser
    Intervention: Drug: MiraLax (polyethylene glycol 3350)
