Lactulose
Lactulose
Lactulose (/lækˈtjuːloʊs/) is a synthetic, non-digestible sugar used in the treatment of chronic constipation and hepatic encephalopathy, a complication of liver disease. It is a disaccharide (double sugar) that is made of fructose and galactose.
Etymology
The term "Lactulose" is derived from the names of its constituent sugars, lactose and fructose. It was first synthesized in the 1920s.
Usage
Lactulose is used in the treatment of constipation and to reduce the amount of ammonia in the blood of patients with liver disease. It works by drawing water into the bowel, which softens the stool and promotes bowel movement. In patients with liver disease, it helps to prevent the absorption of ammonia into the blood.
