Mechanism of action

PEG-Asc (polyethylene glycol with ascorbic acid) works as an osmotic laxative that draws water into the bowel to promote evacuation, while ascorbic acid reduces the volume needed compared to standard PEG solutions. Simethicone is an anti-foaming agent that breaks down gas bubbles in the colon, improving visualization during endoscopy and reducing patient discomfort.
