🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works as an osmotic laxative. Lactitol is a disaccharide sugar alcohol that is poorly absorbed in the small intestine. It reaches the colon unchanged, where it exerts an osmotic effect, drawing water into the intestinal lumen. This increases stool water content and volume, stimulating peristalsis and facilitating defecation. In hepatic encephalopathy, colonic bacteria metabolize lactitol into organic acids, which lower colonic pH. This acidification converts ammonia to ammonium ions, which are poorly absorbed, thereby reducing blood ammonia levels.
Mechanism Steps
💡 How to Take constez powder
Strength: Powder for oral solution, 10 grams per sachet.
Dosage Information
| Adult Dosage | The usual adult dose for constipation is 10 to 20 grams of lactitol powder dissolved in a glass of water, taken once daily, preferably in the morning. For hepatic encephalopathy, the dose is individualized based on blood ammonia levels and clinical response, typically 20 to 30 grams two to three times daily. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may be more susceptible to dehydration and electrolyte imbalance. Use with caution and monitor hydration status. Dose should be individualized by a clinician. |
| Renal Impairment | No specific dose adjustment is established. Use with caution in patients with renal impairment due to risk of electrolyte imbalance from diarrhea. |
| Hepatic Impairment | No specific dose adjustment is required for hepatic impairment. This medicine is used in hepatic encephalopathy; dose is individualized based on clinical response and ammonia levels. |
| Maximum Daily Dose | The maximum daily dose for constipation is generally 20 grams; for hepatic encephalopathy, up to 90 grams daily may be used under medical supervision. Dose must be individualized by a qualified clinician. |
