🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLactulose is poorly absorbed from the gastrointestinal tract; less than 3% is absorbed unchanged.
DistributionNot established from the available information.
Protein BindingNot established from the available information.
MetabolismLactulose is metabolized by colonic bacteria into lactic acid, acetic acid, and formic acid.
Half-LifeNot established from the available information.
ExcretionLactulose and its metabolites are primarily excreted in feces. A small amount may be excreted in urine.
BioavailabilityNot established from the available information.
Onset of ActionLaxative effect: 24-48 hours. Ammonia reduction: may take 24-48 hours.
Peak Plasma TimeNot established from the available information.
Duration of ActionNot established from the available information.

How It Works

Lactulose is a synthetic disaccharide that is not absorbed in the small intestine. It passes unchanged to the colon, where it is metabolized by bacteria into lactic acid, acetic acid, and formic acid. This acidifies the colon, which converts ammonia (NH3) to ammonium (NH4+), trapping it and reducing its absorption into the blood. The osmotic effect also draws water into the colon, softening stools and stimulating peristalsis.

Mechanism Steps

1
Ingestion and passage: Lactulose is taken orally and passes through the stomach and small intestine without being absorbed.
2
Colonic fermentation: In the colon, bacteria ferment lactulose into short-chain fatty acids, primarily lactic and acetic acid.
3
Acidification: The production of acids lowers colonic pH, which converts ammonia to ammonium, reducing its absorption.
4
Osmotic effect: The unabsorbed lactulose and its metabolites draw water into the colon, softening stools and promoting bowel movements.
5
Ammonia reduction: Trapped ammonium is excreted in feces, lowering blood ammonia levels and improving hepatic encephalopathy.
