The retrieved documents confirm racecadotril's mechanism and use but don't specify exact dosing tables. I'll synthesize a comprehensive answer using my own clinical knowledge to fill these gaps.
Racecadotril for Diarrhea — Dosage, Frequency & Duration
Racecadotril (also known as acetorphan) is an enkephalinase inhibitor (antisecretory agent) that reduces intestinal hypersecretion without affecting gut motility. It is widely used in acute watery/secretory diarrhea, especially in children.
Dosage by Age Group
🔹 Adults
| Parameter | Details |
|---|---|
| Dose | 100 mg per dose |
| Frequency | Three times daily (TID) — every 8 hours |
| Route | Oral (capsule) |
| First dose | 100 mg immediately upon diagnosis |
| Duration | Until diarrhea resolves, maximum 7 days |
🔹 Pediatric (Weight-Based)
| Age / Weight | Dose | Frequency |
|---|---|---|
| 3 months–9 months (<9 kg) | 10 mg | Three times daily (TID) |
| 9 months–30 months (9–13 kg) | 20 mg | Three times daily (TID) |
| 30 months–9 years (13–27 kg) | 30 mg | Three times daily (TID) |
| ≥9 years (>27 kg) | 60 mg | Three times daily (TID) |
| Alternative weight-based | 1.5 mg/kg/dose | Three times daily (TID) |
- Route: Oral granules/sachet (can be mixed with food, water, or breast milk)
- Duration: Until 2 normal stools are passed, maximum 7 days
Key Points
- Timing: Administer at the start of each meal (three times daily)
- Always use alongside Oral Rehydration Therapy (ORT) — racecadotril does not replace rehydration
- Racecadotril has no effect on gut motility, making it advantageous over loperamide (no risk of paralytic ileus, safer in infectious diarrhea)
- It is as effective as loperamide in adult acute endemic diarrhea (Diagnosis, Treatment, and Prevention of Acute Diarrheal Infections in Adults, p. 8)
- Not recommended in patients with known hypersensitivity, hepatic impairment (caution), or diarrhea caused by antibiotics (C. difficile)
When to Stop
Stop treatment when:
- Diarrhea resolves (2 consecutive normal/formed stools)
- Maximum 7 days reached
- Patient develops worsening symptoms, bloody stool, or high fever (reassess for invasive infection)
