PHARMACOLOGICAL PROPERTIES
- Lactulose is a synthetic derivative of lactose.
- It is not broken down in the stomach or small intestine and is minimally absorbed.
Mechanism of action:
- stimulates intestinal peristalsis;
- promotes ammonia removal from blood into the intestine;
- improves absorption of phosphate and calcium;
- in the colon, it is metabolized by gut bacteria into organic acids (lactic, acetic, formic acids).
Effects in the colon:
- lowers pH;
- increases osmotic pressure;
- increases stool volume;
- stimulates peristalsis;
- normalizes stool consistency.
Result:
- relief of constipation;
- restoration of normal bowel movement rhythm;
- ammonia elimination.
Onset of action:
- within 24–48 hours.
CONTRAINDICATIONS
·hypersensitivity to components of the drug;
·galactosemia;
·lactose, galactose or fructose intolerance;
· intestinal obstruction.
ADVERSE REACTIONS
astrointestinal system:
- flatulence
- abdominal pain
- nausea
- vomiting
With long-term use:
- possible disturbances of water and electrolyte balance.
DRUG INTERACTIONS
Diuretics, corticosteroids, amphotericin B:
- may increase potassium loss (hypokalemia).
Antacids and antibiotics affecting gut flora (e.g., neomycin, clindamycin, rifaximin):
- may reduce the effect of lactulose.
Enteric-coated / pH-dependent drugs:
- lactulose lowers intestinal pH and may alter drug release and effectiveness.
SPECIAL PRECAUTIONS
Should not be used in case of abdominal pain, nausea, or vomiting without confirmed diagnosis.
Not recommended in acute inflammatory gastrointestinal diseases or electrolyte imbalance.
Use with caution in gastrocardiac syndrome:
- start with low doses,
- increase gradually to avoid flatulence.
Use with caution in patients with diabetes mellitus, especially with inflammatory colon disease.
During long-term use (>6 months):
- monitor potassium, chloride, and CO₂ levels in blood plasma.
Adequate fluid intake is recommended:
- 1.5–2 L/day (6–8 glasses of 250 ml).
