Other Names. When sold for gut cleansing (and as a laxative), it is usually in combination with salts such as sodium bicarbonate, sodium chloride and potassium chloride to help mitigate the possibility of electrolyte imbalance and dehydration.  Since purification and separation of pure oligomers is difficult, the price for this type of quality is often 10–1000 fold that of polydisperse PEG. It relieves constipation because it causes water to be retained in the bowel instead of being absorbed into the body.  Use appears to be safe during pregnancy.  Benefits usually occur within three days. PEG is commonly used as a crowding agent in in vitro assays to mimic highly crowded cellular conditions. Macrogols are also attached to biopharmaceutical drugs to slow down their degradation in the human body and increase their duration of action, as well as to reduce immunogenicity.
