Pharmacokinetics

AbsorptionPoorly absorbed from the gastrointestinal tract; reaches colon unchanged.
DistributionMinimal systemic distribution; acts locally in the colon.
Protein BindingNegligible
MetabolismMetabolized by colonic bacteria to short-chain fatty acids (lactic acid, acetic acid, formic acid).
Half-LifeNot applicable due to local action; systemic absorption is minimal.
ExcretionPrimarily excreted in feces; minimal renal excretion.
BioavailabilityLess than 3% systemically
Onset of Action6-12 hours (oral)
Peak Plasma TimeNot applicable; local action.
Duration of ActionVariable; depends on dose and individual response.

How It Works

Lactulose is a synthetic disaccharide that is not absorbed in the small intestine. In the colon, it is metabolized by bacteria to organic acids, which lower the pH and increase osmotic pressure, drawing water into the colon and stimulating bowel movements.

Mechanism Steps

1Lactulose reaches the colon unchanged.
2Colonic bacteria (e.g., Lactobacillus, Bacteroides) metabolize lactulose to short-chain fatty acids (lactic acid, acetic acid, formic acid).
3These acids lower the colonic pH.
