Lactulose (Kristalose) is a synthetic, non-digestible double-sugar (disaccharide) used to treat chronic constipation and a complication of liver disease. It is formed from one molecule each of simple sugars fructose and galactose. In patients with a history of chronic constipation, lactulose therapy increases the number of bowel movements per day.
