🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by osmosis. Lactulose is a synthetic disaccharide that is not absorbed in the small intestine. It passes into the colon where it is metabolized by bacteria into organic acids. These acids draw water into the colon, softening the stool and stimulating peristalsis. In hepatic encephalopathy, the acidification of the colon traps ammonia in the form of ammonium ions, which are then excreted in the stool, reducing blood ammonia levels.
