4L PEG
4L PEG, marketed by Changhai Hospital, is an osmotic laxative used for bowel evacuation. Its key strength lies in its mechanism of action, which effectively draws water into the colon to facilitate cleansing. The primary risk is the patent expiry in 2028, which could lead to increased competition from generics.
