Lactulose is a type of sugar. It is broken down in the large intestine into mild acids that draw water into the colon, which helps soften the stools. Lactulose is used to treat chronic constipation. Lactulose is sometimes used to treat or prevent certain conditions of the brain that are caused by liver failure, which can lead to confusion, problems with memory or thinking, behavior changes, tremors, feeling irritable, sleep problems, loss of coordination, and loss of consciousness. Lactulose may also be used for purposes not listed in this medication guide.
Constulose is a colonic acidifier that promotes laxation. It is usually prescribed to patients who have chronic constipation, which is defined as having infrequent or difficult bowel movements. Constulose solution therapy increases bowel movements per day. Changes in diet may also help to increase the ease and frequency of bowel movements.
