Lactulose is a synthetic sugar used to support bowel function. It is commonly prescribed to help regulate bowel movements and manage certain liver-related conditions. It may also be used under medical supervision to prepare the bowel for procedures such as colonoscopy.

Lactulose works by drawing water into the colon, which softens stools and stimulates bowel movements. It also helps promote the growth of beneficial gut bacteria and reduces the presence of potentially harmful bacteria. In liver-related conditions, it helps reduce the absorption of substances like ammonia that can affect brain function.
