Reduced cathartic bowel preparation for CT colonography: prospective comparison of 2-L polyethylene glycol and magnesium citrate. [2011.10]
PURPOSE: To prospectively compare adequacy of colonic cleansing, adequacy of solid stool and fluid tagging, and patient acceptance by using reduced-volume, 2-L polyethylene glycol (PEG) versus magnesium citrate bowel preparations for CT colonography... CONCLUSION: Reduced-volume PEG and magnesium citrate bowel preparations demonstrated adequate cleansing effectiveness for CT colonography, with better tagging and shorter interpretation time observed in the PEG group. Adequate polyp detection was maintained but requires further validation because of the small number of clinically important polyps. (c) RSNA, 2011.
Effect of bowel preparation with polyethylene glycol on quality of capsule endoscopy. [2011.06]
BACKGROUND AND AIMS: Capsule endoscopy (CE) has the problem that lumen visualization is impaired by bubbles, bile, and debris. The benefits of bowel preparation are still controversial and the best method remains to be determined. The objective of this study was to evaluate the effect of the method of bowel preparation on the quality of visualization and on transit time... CONCLUSIONS: Bowel preparation with PEG resulted in better image quality than fasting alone. No significant difference was observed between 2 and 4 l. PEG 2 l rather than 4 l may be a useful method of preparation for CE.
MiraLAX is not as effective as GoLytely in bowel cleansing before screening colonoscopies. [2011.04]
BACKGROUND & AIMS: Successful colonoscopies require good bowel preparations-poor bowel preparations can increase medical costs, rates of missed lesions, and procedure duration. The combination of polyethylene glycol (PEG) 3350 without electrolytes (MiraLAX; Schering-Plough Healthcare Products, Inc, Kenilworth, NJ) and 64 oz of Gatorade (PepsiCo, Inc, Purchase, NY) has gained popularity as a bowel preparation regimen. However, the efficacy and tolerability of this approach has not been compared with standard bowel preparations in clinical trials. We compared split-dose (PEG) 3350 with electrolytes (GoLytely; Braintree Laboratories, Inc, Braintree, MA) with split-dose MiraLAX alone and in combination with pretreatment medications (bisacodyl or lubiprostone) to determine the efficacy and patient tolerability of MiraLAX as an agent for bowel preparation... CONCLUSIONS: Split-dose MiraLAX in 64 oz of Gatorade is not as effective as 4 L split-dose GoLytely in bowel cleansing for screening colonoscopies. Copyright (c) 2011 AGA Institute.

Low-volume bowel preparation is inferior to standard 4 1 polyethylene glycol. [2011.03]
BACKGROUND: Four liters or more of orally taken polyethylene glycol solution (PEG) has proved to be an effective large-bowel cleansing method prior to colonoscopy. The problem has been the large volume of fluid and its taste, which is unacceptable to some examinees. We aimed to investigate the effectiveness of 2 l PEG combined with senna compared with 4 l PEG for bowel preparation... CONCLUSIONS: 4 l PEG treatment is better than 36 mg senna and 2 l PEG as routine colonic cleansing before colonoscopy because of fewer failures.
Comparison of the effectiveness of polyethylene glycol 4000 without electrolytes and magnesium hydroxide in the treatment of chronic functional constipation in children. [2011.01]
OBJECTIVE: To compare the effectiveness of two drugs, polyethylene glycol 4000 without electrolytes and magnesium hydroxide, in the treatment of chronic functional constipation in children... CONCLUSION: The two laxatives showed no difference in effectiveness for the treatment of constipation. However, due to its better acceptance, because it is odorless and tasteless, polyethylene glycol proved to be a better option for treating chronic functional constipation.
Clinical Trials Related to Miralax (Polyethylene Glycol 3350)
Miralax (PEG 3350) vs. Golytely as Bowel Preparation for Screening Colonoscopy [Recruiting]
A major limitation to the widespread acceptance of colonoscopy as a procedure to screen for
colorectal cancer is the laxative preparation. Phosphate-based preps (e. g. Fleets
Phosphosoda) are now used on a limited basis because of their known association with renal
injury. Polyethylene glycol (PEG) mixed with a balanced electrolyte solution (e. g. Golytely)
has been used for over two decades for colon cleansing. The mixture is not very palatable
due to the electrolyte additives which include sodium sulfate.
To overcome the limitation of existing preps, gastroenterologists and colorectal surgeons
worldwide have been using PEG powder alone (same quantity as found in Golytely prep) not
mixed with electrolytes (Glycolax or Miralax) and dissolving this into 64 ounces of
Gatorade. Conservatively, we estimate that 25% of colonoscopies in the US are being done
with this prep. Anecdotally there have been reports (case series) that it is far more
palatable and the prep is equally efficacious. The active ingredient, PEG, is not changed
and therefore this is not surprising. The issue at present is that there has never been a
blinded study to confirm these claims.
This study will compare the efficacy of the two preps. There is no funding. The
investigators will charge insurance companies for the prep - this is our current practice.
The procedures will be done on healthy individuals referred for colon cancer screening and
the exam will be billed to their insurance. There will be no patient honorarium. The
investigators will check electrolytes to be sure patients do not develop hypokalemia with
the Gatorade prep.
A Trial Comparing Split-Dose Miralax With Amitiza Pretreatment Versus Dulcolax Pretreatment for Bowel Cleansing Prior to Colonoscopy [Recruiting]
Miralax (PEG 3350) has been shown to be a safe and uncomplicated bowel preparation prior to
colonoscopy in pediatric populations. This study seeks to confirm the efficacy of this bowel
cleansing regimen in adults and to determine the benefit of adding a pretreatment medication
to this bowel preparation. The tolerability of Miralax will hopefully improve patient
satisfaction with colonoscopy and decrease their reluctance to be screened because of the
uncomfortable taste and side effects of bowel preparation regimens.
Gatorade/Miralax With or Without Bisacodyl Versus NuLytely for Colonoscopy Preparation [Recruiting]
The purpose of this study is to compare Nulytely (or Trilyte) with a Gatorade and Miralax
combination for cleaning out the colon before colonoscopy. A laxative pill called Bisacodyl
may also be used with the Gatorade and Miralax to see if it helps with the clean out
process. We are trying to find out if either of these methods is more acceptable to the
patient and does a better job cleaning out the colon for a colonoscopy.
Efficacy and Patient Satisfaction of Miralax and Gatorade Versus Movi Prep [Recruiting]
This study will be comparing patient satisfaction, efficacy comparing miralax with gatorade
versus Movi Prep for outpatient colonoscopy.
Efficacy Study of Polyethylene Glycol 3350-electrolyte Solution (GoLYTELY´┐Ż) Versus Lactulose in Patients With Hepatic Encephalopathy. [Recruiting]
This study is being done to find out if the laxative polyethylene glycol (also known as
GoLYTELY« or Miralax«) can treat your hepatic encephalopathy (confusion due to your liver
disease and/or cirrhosis) better and/or more safely than lactulose (another laxative). In
this study, the investigators will evaluate if polyethylene glycol (GoLYTELY«) is more
effective than lactulose on neurocognition (memory and thinking skills) and determine if it
decreases the hospital stay.

Miralax review by 45 year old female patient
|Overall rating:|| || |
|Effectiveness:|| || Considerably Effective|
|Side effects:|| || No Side Effects|
|Condition / reason:|| || irritable bowel syndrome|
|Dosage & duration:|| || 1 capful taken once a day for the period of Three consecutive days|
|Other conditions:|| || none|
|Other drugs taken:|| || none|
|Benefits:|| || Helped ease constipation without causing discomfort. I have tried many different types of laxatives, fibers, etc to help reduce my problems with constipation. Many laxatives cause extreme cramping and work only the one time. The next day, the problem returns. With Miralax, I took it for the three consecutive days and it worked slowly, but without cramping, and without and discomfort at all. The effects lasted for several weeks -- that is, I had a bowel movement every day, easily. After about three weeks I needed to take it again, but it was only for the three days and then it had the same effect. I have been doing this now for almost a year. I feel significantly better.|
|Side effects:|| || None|
|Comments:|| || I take Miralax in the evening, mixing it with a cup of warm water. After about three days, it starts to work. It does not "clean out" my stomach -- just helps me to have easy and regular bowel movements. I have to repeat the three-day program every three weeks or so. When I notice I have not had a bowel movement for a few days, then I take it again. For me, this is a great help. |
