Lactolux Oral Solution Sugar Free contains Lactulose 3.33mg per 5ml and is indicated primarily for the treatment of constipation and hepatic encephalopathy. Lactulose is a synthetic disaccharide that is not absorbed in the small intestine but metabolized by colonic bacteria into low molecular weight organic acids, resulting in an osmotic effect that increases stool water content, thereby softening stools and promoting bowel movements. The sugar-free formulation makes it suitable for patients with diabetes or those requiring sugar-restricted diets. Lactolux is administered orally, with dosage individualized based on patient response and clinical condition. In constipation, it facilitates regular bowel movements, while in hepatic encephalopathy, it reduces blood ammonia levels by promoting the growth of non-urease-producing bacteria and acidifying colonic contents, which helps prevent the absorption of ammonia. Common adverse effects may include flatulence, abdominal discomfort, and diarrhea, typically resolving with dosage adjustment. Lactolux should be used cautiously in patients with galactosemia or those with a history of hypersensitivity to lactulose. Regular monitoring is advised during prolonged therapy. This product is intended for use under medical supervision to ensure optimal therapeutic outcomes and minimize potential side effects.
