Duphalac Syrup Uses

Duphalac syrup has lactulose, which makes up the main Duphalac syrup composition, and is an ingredient that helps to treat constipation. It also increases the frequency of how many days the bowel movement takes place, as well as the frequency of it happening in a day. This is done by increasing the content of water in the intestines, resulting in softening of the stool. This is a syrup that does not get absorbed into the person’s body.

Lactulose is an ingredient that is a sugar, but it is a synthetic man-made sugar. What it does is that it breaks down in the large intestine, after which it will draw water in the intestine. And as mentioned, this softens stool and greatly helps with constipation.

Another one of Duphalac syrup uses comes from the fact that lactulose is used in treating high ammonia levels in the blood that can occur because of liver disease. Higher levels of ammonia could lead to what is known as portal-systemic encephalopathy. This drug draws ammonia into the large intestine from the bloodstream. And then, ammonia is removed from the body through the stool.
