MOVELAX Lactulose 3.3g / 5mL Syrup 120mL
Indications/Uses
Prevention and treatment of portal systemic encephalopathy (PSE) including the stages of hepatic pre-coma and coma.
For patients with hemorrhoids, after colon/anal surgery or other conditions where a soft stool is beneficial.
Dosage/Direction for Use
Subsequent doses should be adjusted to produce 2 or 3 soft stools daily.
Prevention of hepatic coma: Initial Dose in Adults: 25 mL three times daily.
Subsequent doses should be adjusted to obtain soft stools.
Administration
Special Precautions
Lactulose contains some free galactose and lactose. Diabetic patients and those with lactose intolerance should use lactulose with caution since blood glucose may be elevated, usually after extended use.
Patients should consult their physicians if any unusual diarrhea occurs.
Elderly or debilitated patients using lactulose for more than 6 months should have their serum electrolytes (i.e., potassium, chloride, carbon dioxide) periodically measured.
Adverse Reactions
Some consider the taste unpleasant. This can be minimized by dilution of water, fruit juice, or milk, or by mixing the dose with food.
Action
Pharmacology: Lactulose is a synthetic disaccharide osmotic laxative containing galactose and fructose. Colonic bacteria break lactulose primarily to lactic and acetic acid which results in an increased osmotic effect and slight acidification of the colonic contents. This results in an increased fecal bulk, softened stools and shortened transit time. It may take 48 hours before an effect is obtained.
Lactulose exerts its effect only in the colon. It decreases blood ammonia concentrations by acidifying the contents of the bowel reducing intraluminal pH to below 5. This reduces the degree of portal systemic encephalopathy since the absorption of ammonium ions and other toxic nitrogenous compounds into the blood is decreased.
Pharmacokinetics: Bioavailability: Lactulose is poorly absorbed from the gastrointestinal tract after oral administration. No enzyme present in human gastrointestinal tissue is capable of hydrolysis of this disaccharide. Lactulose reaches the colon virtually unchanged with less than 2% being absorbed by non-mediated diffusion. Urinary excretion is less than or equal to 3% and is essentially complete within 24 hours.
