Lactulose STELLA

Lactulose exerts a local osmotic effect in the colon, and causes an increase in water content of the stool and softening of the stool and stimulates the colonic peristalsis. This effect on the stool may be seen until for 72 hours after administration of the drug. Lactulose decreases blood ammonia levels then it is used in treatment of hepatic encephalopathy, but this effect demands the use of high dose.
