LACUYES (Lactulose Concentrate Solution)

Description

LACUYES contains Lactulose, a synthetic, non-absorbable disaccharide widely used as an osmotic laxative. It is particularly effective in managing chronic constipation and preventing/treating hepatic encephalopathy by reducing systemic ammonia levels. Suitable for long-term use due to its non-habit forming nature.

Mechanism of Action (MOA)

• Reaches colon unchanged (not digested in small intestine)
• Fermented by gut flora → lactic acid, acetic acid
• ↓ Colonic pH → converts ammonia (NH₃) to ammonium (NH₄⁺)
• Osmotic effect → increases water retention in stool
• Stimulates peristalsis → promotes bowel movement

Pharmacokinetics

• Absorption: Negligible systemic absorption
• Onset: 24–48 hours
• Metabolism: By colonic bacteria
• Excretion: Feces

Uses

• Chronic constipation (first-line osmotic laxative)
• Hepatic encephalopathy (reduces ammonia toxicity)
• Portal-systemic encephalopathy
• Pre/post-operative bowel regulation

Dosage (General)

• Constipation: 15–30 ml daily (adjust based on response)
• Hepatic encephalopathy: 30–45 ml 3–4 times/day

Side Effects

• Common: Flatulence, bloating, abdominal discomfort
• Dose-related: Diarrhea
• Long-term: Electrolyte imbalance (Na⁺, K⁺ disturbances)

Precautions

• Monitor electrolytes in elderly & long-term use
• Use cautiously in diabetics (contains sugars)
• Avoid in galactosemia
• Ensure adequate fluid intake

Drug Interactions

• Antacids may reduce efficacy
• Antibiotics may alter gut flora → reduced effect
