Acilac (lactulose-oral)

What is lactulose-oral, and how does it work (mechanism of action)?

Lactulose is a man-made sugar that contains two naturally occurring sugars, galactose and fructose. It is not digested in the intestine like other sugars so that it reaches the colon where bacteria digest it and thereby alter the composition of the stool.
Lactulose is used as a laxative to treat constipation. In the colon, lactulose is broken down by bacteria into products that help to draw water into the colon, which softens the stool.
Additionally, lactulose is used to treat hepatic encephalopathy, a loss of brain function and change in mentation that occurs when the liver is unable to remove toxins from the blood. Bacteria in the colon digest lactulose into chemicals that bind ammonia that is believed to be the toxin that causes hepatic encephalopathy. The binding of ammonia prevents ammonia from moving from the colon into the blood and also draws ammonia from the blood and into the colon. The bound ammonia then is removed from the body in the stool.
The FDA approved lactulose in March, 1976.
