What is Macrogol / polyethylene glycol oral osmotic laxative - Meaning and definition

An isotonic solution containing macrogol 3350 and electrolytes with laxative activity.
Macrogol 3350-based oral osmotic laxative promotes the retention of water in the bowel, thereby increasing the water content of stool, which results in increased gastrointestinal motility and stool transit time and evacuation of colonic contents.

Macrogol 3350 is also known as polyethylene glycol (PEG) 3350.
