🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLactulose is poorly absorbed from the gastrointestinal tract. Only about 0.4% to 2% of an oral dose is absorbed unchanged. The majority reaches the colon intact.
DistributionAbsorbed lactulose is distributed in extracellular fluids, but because absorption is minimal, distribution is not clinically significant.
Protein BindingNot established from the available information.
MetabolismLactulose is not metabolized by human enzymes. It is fermented by colonic bacteria into short-chain fatty acids.
Half-LifeNot established from the available information.
ExcretionUnabsorbed lactulose and its metabolites are excreted primarily in the feces. The small absorbed fraction is excreted unchanged in the urine.
BioavailabilityOral bioavailability is very low, approximately 0.4% to 2%.
Onset of ActionLaxative effect typically occurs within 24 to 48 hours, but may take up to 3 days for full effect. For hepatic encephalopathy, improvement may be seen within 24 to 48 hours.
Peak Plasma TimeNot established from the available information.
Duration of ActionThe effect lasts until the lactulose is fully evacuated from the colon, usually 24 to 48 hours after the last dose.

How It Works

Lactulose is a synthetic disaccharide composed of galactose and fructose. It is not absorbed in the small intestine and reaches the colon unchanged. There, colonic bacteria ferment it into lactic acid, acetic acid, and formic acid, which lowers the colonic pH. This acidic environment draws water into the colon osmotically, softening the stool and stimulating peristalsis. In hepatic encephalopathy, the acidification converts ammonia (NH3) to ammonium (NH4+), which is poorly absorbed and is excreted in the feces, 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 or broken down.
2
Colonic fermentation: In the colon, bacteria ferment lactulose into short-chain fatty acids, primarily lactic acid and acetic acid.
3
Osmotic effect: The acidic byproducts draw water into the colon, increasing stool water content and softening the stool.
4
Peristalsis stimulation: The increased volume and softened stool stimulate bowel contractions, promoting defecation.
5
Ammonia trapping: In hepatic encephalopathy, the acidic colon converts ammonia to ammonium, which is trapped and excreted in feces, reducing blood ammonia.

💡 How to Take bowell sachet

Strength: Sachet containing lactulose 3.35 gm (equivalent to 10 g lactulose powder? Actually 3.35 gm lactulose per sachet).

1Dissolve the contents of one sachet in a glass of water (about 200 mL).
2Stir well until the powder is fully dissolved.
3Drink the solution immediately.
4Follow with another glass of water to ensure complete ingestion.
5Take at the same time each day, preferably in the morning.
6Do not take more than the prescribed number of sachets per day.

Dosage Information

Adult DosageThe usual adult dose for constipation is 15-30 mL (containing 10-20 g lactulose) daily, preferably in the morning. For hepatic encephalopathy, the dose is 30-45 mL (20-30 g) 3 to 4 times daily, adjusted to produce 2-3 soft stools per day. The sachet containing 3.35 g lactulose is typically dissolved in water; the number of sachets per day depends on the prescribed dose. 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 require lower initial doses due to increased sensitivity to electrolyte imbalances. Start with the lowest effective dose and monitor hydration and electrolytes. Dose must be individualized by a qualified clinician.
Renal ImpairmentNo specific dose adjustment is provided in the labeling for renal impairment. However, use with caution in severe renal impairment due to risk of electrolyte imbalance. Monitor closely.
Hepatic ImpairmentNo dose adjustment is required for hepatic impairment. In fact, lactulose is used to treat hepatic encephalopathy. Dose is titrated to clinical response.
Maximum Daily DoseFor constipation, the maximum recommended daily dose is 60 mL (40 g lactulose). For hepatic encephalopathy, doses up to 120 mL (80 g) daily may be used under medical supervision. Do not exceed the prescribed dose.
