🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLactulose is minimally absorbed from the gastrointestinal tract; only about 0.4-2% is absorbed unchanged. Ispaghula is not absorbed systemically; it acts locally in the intestine.
DistributionLactulose that is absorbed is distributed in extracellular fluid. Ispaghula is not absorbed and remains in the gastrointestinal tract.
Protein BindingNot established from the available information.
MetabolismLactulose is metabolized by colonic bacteria to lactic acid, acetic acid, and other organic acids. Ispaghula is not metabolized systemically; it is fermented by colonic bacteria to some extent.
Half-LifeNot established from the available information.
ExcretionLactulose and its metabolites are primarily excreted in the feces. Small amounts of absorbed lactulose are excreted unchanged in the urine. Ispaghula is excreted in the feces.
BioavailabilityLactulose has a bioavailability of less than 2% when taken orally. Ispaghula is not systemically bioavailable.
Onset of ActionLactulose typically produces a bowel movement in 24 to 48 hours. Ispaghula usually works within 12 to 24 hours, but full effect may take 2 to 3 days.
Peak Plasma TimeNot applicable for ispaghula. For lactulose, peak plasma levels are negligible due to minimal absorption.
Duration of ActionThe effect lasts until the next bowel movement, typically within 24 to 48 hours after administration.

How It Works

This medicine combines two laxatives with complementary mechanisms. Lactulose is a synthetic disaccharide that is not absorbed in the small intestine. It passes to the colon where it is metabolized by bacteria into organic acids, primarily lactic acid and acetic acid. These acids draw water into the colon osmotically, softening the stool and increasing stool volume, which stimulates peristalsis. Ispaghula is a bulk-forming laxative composed of mucilage from Plantago ovata seeds. It absorbs water to form a gel-like substance, increasing stool bulk and moisture, which promotes bowel movements by stretching the intestinal wall and stimulating peristalsis. Together, they provide both osmotic and bulk-forming effects for effective relief of constipation.

Mechanism Steps

1
Lactulose fermentation: Lactulose reaches the colon unchanged and is fermented by colonic bacteria into short-chain fatty acids.
2
Osmotic effect: The fatty acids draw water into the colon, softening the stool.
3
Ispaghula gel formation: Ispaghula absorbs water to form a gel, increasing stool bulk and moisture.
4
Peristalsis stimulation: The increased volume stimulates stretch receptors in the colon, promoting peristalsis and bowel movement.

💡 How to Take isablac powder

Strength: Each sachet contains lactulose 10 gm and ispaghula 3.5 gm.

1Empty the contents of one sachet into a glass of water (150-200 ml).

The dose may be adjusted based on response. 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 a lower dose due to increased sensitivity. Start with 1 sachet daily and adjust as needed. Dose must be individualized by a qualified clinician.
Renal ImpairmentNo specific dose adjustment is required for renal impairment, but use with caution in patients with severe renal impairment due to risk of electrolyte imbalance.
Hepatic ImpairmentNo specific dose adjustment is required for hepatic impairment. However, in severe hepatic impairment, lactulose may be used for hepatic encephalopathy, but this combination is not indicated for that purpose.
Maximum Daily DoseThe maximum recommended daily dose is 4 sachets (40 gm lactulose and 14 gm ispaghula). Do not exceed without medical advice.
