🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLactulose is poorly absorbed from the gastrointestinal tract. Only about 0.4-2% of an oral dose is absorbed unchanged.
DistributionAbsorbed lactulose is distributed in extracellular fluids, but the majority remains in the gastrointestinal tract.
Protein BindingNot established from the available information.
MetabolismLactulose is metabolized by colonic bacteria into lactic acid, acetic acid, and formic acid. It is not metabolized by human enzymes.
Half-LifeNot established from the available information.
ExcretionLactulose is primarily excreted in the feces as unchanged drug and metabolites. A small amount of absorbed drug is excreted in urine.
BioavailabilityLow, approximately 0.4-2% of an oral dose is absorbed.
Onset of ActionLaxative effect typically occurs within 24 to 48 hours, but may take up to 48 hours for full effect.
Peak Plasma TimeNot established from the available information.
Duration of ActionThe laxative effect lasts until the drug is cleared from the colon, usually within 24 to 48 hours after a dose.

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 colonic bacteria into lactic acid, acetic acid, and formic acid. These acids draw water into the colon osmotically, softening the stool and stimulating peristalsis. In hepatic encephalopathy, the acidification of the colon converts ammonia to ammonium ions, which are less absorbable, thereby reducing blood ammonia levels.

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 acid and acetic acid.
3
Osmotic effect: The acids draw water into the colon, increasing stool water content and softening the stool.
4
Peristalsis stimulation: The increased volume stimulates colonic peristalsis, promoting bowel movements.
5
Ammonia reduction: In hepatic encephalopathy, the acidification of the colon converts ammonia to ammonium, which is less absorbed, reducing blood ammonia levels.

Dosage Information

Adult DosageThe usual adult dose for constipation is 15-30 mL (10-20 g) daily, preferably at bedtime. For hepatic encephalopathy, the dose is 30-45 mL (20-30 g) three to four times daily, adjusted to produce 2-3 soft stools per day. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more sensitive to the effects of lactulose, especially dehydration and electrolyte imbalance. Start with a lower dose and monitor closely. Dose must be individualized by a qualified clinician.
Renal ImpairmentUse with caution in patients with renal impairment. Monitor hydration and electrolytes. Dose adjustment may be necessary. Consult a doctor.
Hepatic ImpairmentNo specific dose adjustment is required for hepatic impairment, but lactulose is used to treat hepatic encephalopathy. Dose is titrated to clinical response. Consult a doctor.
Maximum Daily DoseFor constipation, the maximum recommended daily dose is 60 mL (40 g). For hepatic encephalopathy, doses up to 120 mL (80 g) daily may be used under medical supervision.
