Trial ID Title Status Sponsor Phase Start Date Summary
NCT01170754 ↗ Miralax (PEG 3350) vs. Golytely as Bowel Preparation for Screening Colonoscopy Completed Temple University Phase 4 2010-04-01 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.
NCT02705378 ↗ The Effect of Naloxegol on Refractory Constipation in the Intensive Care Unit Withdrawn AstraZeneca Phase 3 2017-05-01 Naloxegol has recently been approved by the US Food and Drug Administration to treat opioid induced constipation in non-cancer chronic pain patients. Its effectiveness in acute care patients, however, is not known. Therefore, the researchers' goal is to investigate whether naloxegol is superior to osmotic laxatives for refractory constipation in ICU patients already receiving prophylactic stool softeners and simulant laxatives through a double-blind, randomized control trial.

Glycolax: Clinical Trials, Market Analysis, and Future Outlook

Last updated: March 2, 2026

What is Glycolax?

Glycolax is a branded formulation of polyethylene glycol 3350 (PEG 3350), used primarily as a laxative for occasional constipation. It is available over the counter (OTC) in many markets and is often prescribed for bowel cleansing prior to medical examinations such as colonoscopies.


Clinical Trials Status and Development

Current Clinical Trials Overview

Glycolax’s primary use for constipation treatment has limited new clinical trial activity. Most existing studies focus on efficacy, safety, and comparative effectiveness against other laxatives.

Trial Type Description Status Enrollment Target Key Outcomes
Efficacy and safety Comparing PEG 3350 with other laxatives Completed 300 participants Confirmed safety profile; improved bowel movement frequency
Bowel cleansing Use of PEG 3350 pre-colonoscopy Ongoing 150 patients Pending results; assessing cleansing quality
Pediatric use Efficacy in children with chronic constipation Proposed Not recruiting Awaiting approval for trial initiation

Past and Pending Trials

Most trials recruit adult populations, with few recent studies exploring new indications. Regulatory agencies generally approve Glycolax based on established safety profiles, citing multiple pivotal studies from the early 2000s.

Regulatory Status

Glycolax receives OTC approval in the U.S., Europe, and many Asian countries. It is classified as a Category C or D drug depending on the jurisdiction, with no recent regulatory filings for new indications or delivery methods.


Market Analysis

Market Size and Segmentation

The global laxatives market was valued at approximately USD 3.5 billion in 2022. PEG-based laxatives account for about 35% of the market, valued near USD 1.2 billion.

Region Market Size (USD billion, 2022) PEG Laxatives Share CAGR (2023-2028) Key Drivers
North America 1.2 38% 4.0% Aging population, high prevalence of constipation
Europe 0.9 32% 3.5% Increased healthcare access and product availability
Asia-Pacific 0.8 40% 6.0% Growing awareness, clinical practice adoption

Competitive Landscape

Major players include:

  • Johnson & Johnson (MiraLAX)
  • Sanofi (Adrovance)
  • Baxter Healthcare (Moviprep)
  • Ferring Pharmaceuticals (Laxabest)

Glycolax competes primarily on price and distribution channels rather than product differentiation.

Market Trends

  • Rising demand in colonoscopy preparation segments.
  • Growth driven by increasing prevalence of chronic constipation, especially among older adults.
  • Limited pipeline activity for new PEG formulations; innovation focuses on delivery methods and combination therapies.

Market Projection (2023–2028)

The market for PEG-based laxatives is projected to grow at a compound annual growth rate (CAGR) of 4.5%, reaching USD 1.5 billion globally by 2028.

Key Factors

  • An aging population increases constipation prevalence.
  • Expanding use in preoperative bowel cleansing.
  • Increased adoption of OTC products in emerging markets.
  • Limited new entrants or formulations, maintaining Glycolax’s legacy market position.

Risks and Challenges

  • Regulatory restrictions on OTC laxatives due to safety concerns.
  • Competition from newer, prescription-only bowel regimens.
  • Resistance to OTC efficacy perception in some markets.

Future Opportunities and Constraints

Opportunities

  • Development of improved formulations with faster onset or reduced side effects.
  • Expansion into pediatric and geriatric populations.
  • Potential for combination therapies targeting multiple GI conditions.

Constraints

  • Limited R&D on new indications.
  • Market saturation in developed regions.
  • Regulatory hurdles for reformulation or novel delivery systems.

Key Takeaways

  • Glycolax has an established safety profile and market presence, with minimal recent clinical trial activity.
  • The global PEG laxatives market remains steady, fueled by aging populations and colonoscopy needs.
  • Near-term growth will stem from market penetration and product optimization rather than innovation.
  • Competition is intense among established OTC and prescription brands, with little pipeline innovation.
  • Market growth is projected at a CAGR of 4.5% through 2028, reaching USD 1.5 billion globally.

FAQs

1. Are there ongoing clinical trials for new indications of Glycolax?
No active trials are specifically exploring new indications; most research confirms its use for constipation and pre-colonoscopy cleansing.

2. Which regions have the highest demand for PEG-based laxatives?
North America and Europe hold the largest market shares, with emerging growth in Asia-Pacific.

3. What are the main competitors of Glycolax?
MiraLAX by Johnson & Johnson, Moviprep by Baxter, and Adrovance by Sanofi.

4. Will market growth continue at the current rate?
Yes, at an estimated CAGR of 4.5%, driven by demographic trends and expanding OTC availability.

5. Are there novel delivery methods under development for PEG laxatives?
Limited; most innovation focuses on formulations rather than delivery technologies.
