Lactulose Sandoz

Lactulose Sandoz is an osmotic laxative containing lactulose, a synthetic disaccharide. It works by drawing water into the bowel to soften stools and facilitate bowel movements. It is also used to prevent and treat hepatic encephalopathy, a brain condition caused by severe liver disease, by trapping ammonia in the colon and preventing its absorption into the blood.
