Information About

Lactulose




Lactulose (Generlac®, Cholac®, Constilac®, Enulose®, Acilac®) is a synthetic Sugar used in the treatment of Constipation and Liver Disease . It consists of the Monosaccharides Fructose and Galactose .


CONSTIPATION


In the treatment of chronic Constipation , its metabolites draw water into the bowel, causing a cathartic effect through osmotic action.


HEPATIC ENCEPHALOPATHY


In treating Hepatic Encephalopathy , lactulose helps "draw out" Ammonia (NH3) from the body. The effectiveness of lactulose is somewhat controversial, and whether or not its effects are through ammonia is also controversial as well. Lactulose is metabolized in the Colon by Bacterial Flora to short chain fatty acids, acidifying the colonic contents. This favors the formation of the nonabsorbable NH4+ from NH3, trapping NH3 in the colon and effectively reducing plasma NH3 concentrations.


SIDE EFFECTS


Side effects include Diarrhea and resultant Dehydration and High Sodium Levels . In rare cases or with excess amounts can cause stomach pain, gas, vomiting, or diarrhea.
