  Purpose
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.

Primary Outcome Measures:
  • bowel cleanliness as rated by the boston bowel prep survey [ Time Frame: measured at the time of colonoscopy ]

Secondary Outcome Measures:
  • patient tolerability [ Time Frame: measured at check in to colonoscopy ]

Estimated Enrollment: 432
Study Start Date: May 2009
Estimated Study Completion Date: May 2010
Estimated Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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
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.
Experimental: MiraLax
216 patients will be randomized to take 238 gm of miralax mixed with 64 oz of gatorade for their bowel cleanser
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.
