polyethylene glycol 3350 + electrolytes + ascorbic acid (Shaanxi Licai Group)

Polyethylene glycol 3350 electrolyte + vitamin C is an oral osmotic laxative combination used for bowel preparation prior to colonoscopy or other gastrointestinal procedures. Developed by Shaanxi Licai Group, it consists of polyethylene glycol 3350 (PEG 3350), electrolytes (typically sodium chloride, sodium bicarbonate, and potassium chloride), and ascorbic acid (vitamin C). PEG 3350 acts as the primary osmotic agent, drawing water into the intestinal lumen to induce diarrhea and cleanse the colon. The addition of ascorbic acid and sodium ascorbate enhances the osmotic effect, allowing for a lower volume of fluid intake compared to traditional PEG-only preparations, while the electrolytes help maintain fluid and electrolyte balance during the cleansing process. It is approved in China under the brand name 丽可助.
