🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by two main mechanisms. In the colon, lactulose is broken down by bacteria into lactic acid, acetic acid, and formic acid, which draw water into the stool and soften it. The acidic environment also converts ammonia to ammonium ions, which are less absorbable and are excreted in the stool. This reduces blood ammonia levels, which is helpful in hepatic encephalopathy.
