PEG (Polyethylene Glycol)Versus Lactulose For Treatment Of Overt Hepatic Encephalopathy
PEG (Polyethylene Glycol)Versus Lactulose For Treatment Of Overt Hepatic Encephalopathy
The current standard of care for patients with HE includes non-absorbable
 disaccharides(lactulose);The chemical name for lactulose is
 4-O-β-D-galactopyranosyl-D-fructofuranose.The exact mode of action by lactulose is thought to
 be the conversion to lactic acid and acetic acid by colonic bacteria resulting in
 acidification of the gut lumen. This favors conversion of ammonia (NH3) to ammonium (NH4+),
 which is relatively membrane impermeable; therefore, less ammonia is absorbed by the colon.
 Gut acidification inhibits ammoniagenic coliform bacteria, leading to increased levels of
 nonammoniagenic lactobacilli. Nonabsorbable disaccharides also work as a cathartic, clearing
 the gut of ammonia before it can be absorbed.
Polyethylene glycol electrolyte solution (PEG) is a laxative solution that increases the
 amount of water in the intestinal tract to stimulate bowel movements. It is used safely to
 clean the bowel before colonoscopy.
