🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine is a synthetic disaccharide that is poorly absorbed in the small intestine. It reaches the colon unchanged, where it is metabolized by bacteria into lactic acid and acetic acid. This acidification draws water into the colon, softening the stool and stimulating peristalsis. In hepatic encephalopathy, the acid environment converts ammonia to ammonium ions, which are less absorbable, thereby lowering blood ammonia levels.
Mechanism Steps
💡 How to Take nulax oral solution
Strength: Lactulose 10mg per 5mL syrup
Dosage Information
| Adult Dosage | The usual adult dose for constipation is 15-30 mL (10-20 g) daily, which may be increased to 30-45 mL daily if needed. For hepatic encephalopathy, the dose is typically 30-45 mL three to four times daily, adjusted to produce 2-3 soft stools per day. 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 require lower doses due to increased risk of dehydration and electrolyte imbalance. Dose must be individualized by a qualified clinician. |
| Renal Impairment | Use with caution in patients with renal impairment. Dose adjustment may be needed. Consult a doctor. |
| Hepatic Impairment | No specific dose adjustment is required for hepatic impairment, but use with caution and monitor ammonia levels. |
| Maximum Daily Dose | For constipation: up to 60 mL per day. For hepatic encephalopathy: up to 180 mL per day. Doses above these should only be used under medical supervision. |
