Lactitol

Lactitol Uses, Dosage, Side Effects, Food Interaction and all others data.

In the colon it is broken down to short chain organic acids and increases osmotic pressure in the colon, thereby causing an increase in the stool water content and stool volume.

Lactitol helps to facilitate bowel movements by drawing water into the gastrointestinal tract. The oral administration of lactitol may reduce the absorption of concomitant medications - other oral medications should be administered at least 2 hours before or 2 hours after lactitol.

Uses

Constipation, Hepatic encephalopathy

Lactitol is also used to associated treatment for these conditions: Constipation, Hepatic Encephalopathy (HE), Occasional Constipation, Chronic idiopathic constipation (CIC)

How Lactitol works

Lactitol is an osmotic laxative - it exerts its pharmacologic effect by creating a hyperosmotic environment within the small intestine. The osmotic effect generated by lactitol draws water into the small intestine, which loosens stools and ultimately facilitates bowel movements.

Dosage

Lactitol dosage

2 teaspoonfuls (20 gm) once or twice daily with plenty of water

Side Effects

Abdominal distension, flatulance and abdominal cramp.

Toxicity

The LD₅₀ is 23 g/kg in mice and >30 g/kg in rats.

Experience with acute overdosage is limited, but is likely to involve significant gastrointestinal upset and diarrhea consistent with the pharmacologic profile of lactitol. Overdosage should be managed with symptomatic and supportive measures, where necessary.

Precaution

Lactose intolerance.

Food Interaction

Take with food. The manufacturer recommends administration with meals.

[Moderate] ADJUST DOSING INTERVAL: Lactitol may decrease the absorption of concomitantly administered oral medications.

MANAGEMENT: Lactitol should be administered at least 2 hours before or 2 hours after concomitant oral medications.

Lactitol Drug Interaction

Unknown: tamsulosin, magaldrate / simethicone, magnesium hydroxide, acetaminophen, senna, docusate/senna, cholecalciferol, bifidobacterium infantis / lactobacillus acidophilus / streptococcus thermophilus

Volume of Distribution

Data regarding the volume of distribution of lactitol are unavailable.

Elimination Route

In healthy subjects under fed conditions, oral administration of 20 grams of lactitol resulted in a mean T_max of 3.6 ± 1.2 hours, C_max of 776 ± 253 ng/mL, and a mean AUC of 6,019 ± 1,771 ng*hr/mL.

Half Life

The average half-life of orally administered lactitol is 2.4 hours.

Clearance

Data regarding the clearance of lactitol are unavailable.

Elimination Route

Lactitol is not absorbed in the gastrointestinal tract to any significant extent. The vast majority of an ingested dose is likely degraded into organic acids in the colon and eliminated in the feces.
