Mechanism of action

Macrogol (polyethylene glycol) 4000 is a high-molecular-weight polymer that is poorly absorbed in the gastrointestinal tract. It exerts an osmotic effect by retaining water in the intestinal lumen, increasing stool bulk and moisture content, which facilitates easier passage of feces and relieves constipation. It is commonly used as a bowel preparation agent and for chronic constipation management.
