Mechanism of Action
Macrogol?4000 is a non-absorbable, inert osmotic laxative that retains water in the colon by hydrogen bonding, softening stool and improving GI motility. It’s well-tolerated and effective for constipation and bowel preparation models.
Research Applications & Pharmacology
Chronic constipation models: First-line osmotic laxative in preclinical motility studies
Bowel preparation: Used in animal models for colon cleansing before endoscopy
Formulation science: Excipient studies on solubility, viscosity, and stability
Hydration/electrolyte balance: Ideal for osmotic research owing to negligible absorption
Comparative studies: Demonstrated higher efficacy and tolerability vs. lactulose, with less gas/flatulence
Safety Profile & Handling
Safety: High molecular weight PEG is biologically inert and well tolerated; minimal systemic absorption (<4%)
Possible effects: May cause mild bloating, abdominal pain, diarrhea
Laboratory precautions: Use standard PPE; avoid inhalation of powder; weigh and dissolve with lab-grade water
Storage: Keep in a dry area at room temperature, protected from moisture
Disposal: Dispose of unused powder and solutions per chemical waste protocols
