Accepted forms of contraception are: i.e., implants, injectables, hormonal intrauterine device, combined hormonal contraceptives, sexual abstinence, and vasectomized sexual partner. Premenopausal women who are of childbearing potential must have a negative serum pregnancy test result at screening and a negative urine pregnancy test result at randomization prior to colonoscopy. In the case of oral contraceptive use, women should have been taking the same pill consistently for a minimum of twelve (12) weeks before taking study medication. Sterilized or postmenopausal women may also participate. Women are considered to be postmenopausal and are not considered to be of childbearing potential if they have had twelve (12) months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Subjects Classified as a Responder Defined by "Excellent" or "Good"
Time Frame: During colonoscopy procedure (5-9 hours after completed treatment)
|
The efficacy of overall colon cleansing in terms of responders was measured by a blinded endoscopist using the Modified Aronchick Scale.
Modified Aronchick scale is a 4-point scale that grades colon cleansing as Excellent (>90% of mucosa seen, mostly liquid stool, minimal suctioning needed for adequate visualization), Good (>90% of mucosa seen, mostly liquid stool, significant suctioning needed for adequate visualization), Fair (>90% of mucosa seen, mixture of liquid and semisolid stool, could be suctioned and/or washed) or Inadequate (<90% of mucosa seen, mixture of semisolid and solid stool which could not be suctioned or washed).The participant is considered to be a responder if overall colon cleansing is "excellent" or "good" on this 4-point scale.
