Usage
- This combination is prescribed for the treatment of acute diarrhea, particularly in children. It is also used for persistent diarrhea in adults and children. Other uses include antibiotic-associated diarrhea, traveler’s diarrhea, and H. pylori infection-related diarrhea. It can also be used in diarrhoea-predominant irritable bowel syndrome (IBS-D).
- Pharmacological Classification: Antidiarrheal, Probiotic, Mineral supplement.
- Mechanism of Action: This combination works through multiple pathways. Racecadotril is an antisecretory agent that inhibits enkephalinase, an enzyme that degrades enkephalins. This leads to increased enkephalin levels, reducing water and electrolyte secretion into the intestines. Saccharomyces boulardii is a probiotic yeast that helps restore the balance of intestinal flora by inhibiting the growth of harmful bacteria, breaking down bacterial toxins, stimulating intestinal immune defenses, and promoting the production of beneficial short-chain fatty acids. Zinc is essential for immune function, intestinal cell repair, and has direct anti-diarrheal effects.
Alternate Names
- Racecadotril, Saccharomyces boulardii, and Zinc combination
- Antidiarrheal combination with probiotic and zinc
- Brand Names: A variety of brand names exist depending upon the specific manufacturer and regional market (e.g., Florich R, Editor, Briogut RZ, Gutnix-Z, Kenimix SBR, Lactoact-R).
How It Works
- Pharmacodynamics: Racecadotril reduces intestinal fluid secretion without affecting intestinal motility. Saccharomyces boulardii exerts its probiotic effect by colonizing the gut, producing antimicrobial substances, and modulating the immune response. Zinc enhances intestinal barrier function and has anti-inflammatory effects.
- Pharmacokinetics: Racecadotril is rapidly absorbed after oral administration and is metabolized to the active metabolite thiorphan. It is primarily excreted in the urine. Saccharomyces boulardii is not absorbed systemically and remains within the gastrointestinal tract. Zinc is absorbed in the small intestine.
- Mode of Action: Racecadotril inhibits enkephalinase in the intestinal brush border, increasing the concentration of enkephalins, which inhibit intestinal fluid secretion. Saccharomyces boulardii produces proteases that degrade bacterial toxins, competes with pathogens for nutrients and adhesion sites, and modulates the host immune response. Zinc is involved in numerous cellular processes related to growth, repair, and immune function within the intestinal mucosa.
- Elimination: Racecadotril is eliminated mainly via renal excretion. Saccharomyces boulardii is eliminated in the feces. Zinc is primarily excreted in the feces and to a lesser extent in urine.
Dosage
Standard Dosage
Adults:
- Racecadotril: 100mg three times a day initially, followed by 100mg every 8 hours until diarrhea stops (for individual component, not the combination). Saccharomyces boulardii: 250mg to 500mg one to two times daily (for individual component). Zinc: 20mg per day (for individual component). The combined formulation’s dosage may differ. Always consult a physician for the appropriate dosage of the combined formulation.
Children:
- Racecadotril: 1.5mg/kg three times daily, with dosage and frequency adjusted based on weight and age. Saccharomyces boulardii and Zinc dosage needs to be adjusted based on pediatric guidelines. Always consult a physician for the appropriate dosage of the combined formulation.
- Pediatric Safety Considerations: Use with caution in infants younger than three months. Monitor for dehydration and electrolyte imbalances.
Special Cases:
- Elderly Patients: Dose adjustment may be needed based on renal function.
- Patients with Renal Impairment: Reduce Racecadotril dosage according to renal function. Use Saccharomyces boulardii and zinc with caution.
- Patients with Hepatic Dysfunction: Dose adjustments may be needed for Racecadotril and other components.
- Patients with Comorbid Conditions: Use Saccharomyces boulardii with caution in patients with diabetes, immunocompromised states, or central venous catheters due to the risk of fungal infections.

FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Racecadotril + Saccharomyces boulardii + Zinc?
A: The dosage depends on the specific formulation and the patient’s age and condition. Consult a physician for appropriate dosing guidelines.
Q2: How does this combination compare to other antidiarrheal treatments?
A: Studies suggest that this combination can be more effective than some other antidiarrheal agents, including smectite, probiotics, and zinc alone, in reducing the duration and severity of diarrhea, especially in children.
Q3: Can this combination be used in infants?
A: It should be used with caution in infants younger than three months. Consult a physician before administering to infants.
Q4: What are the key differences between Racecadotril and Loperamide?
A: Racecadotril acts primarily by reducing intestinal fluid secretion, while Loperamide slows intestinal motility. Racecadotril carries a lower risk of rebound constipation.
Q5: What dietary recommendations should be provided to patients with diarrhea?
A: Maintaining adequate hydration is crucial. Patients should increase fluid intake with oral rehydration solutions (ORS) to replace lost electrolytes. A bland diet may be recommended during the acute phase of diarrhea.
Q6: Is this combination effective against all types of diarrhea?
A: It is primarily indicated for acute diarrhea. Its effectiveness in chronic diarrhea or diarrhea caused by certain pathogens may be limited.
Q7: What should be done in case of a missed dose?
A: Take the missed dose as soon as you remember. However, if it’s almost time for the next dose, skip the missed dose and continue with the regular schedule. Do not double the dose.
Q8: Can this combination be used with antibiotics?
A: Yes, it can be used concurrently with antibiotics, and is often prescribed to manage antibiotic-associated diarrhea.
Q9: Are there any specific monitoring parameters for patients taking this combination?
A: Monitor stool frequency and consistency, hydration status, and electrolyte levels, especially in children and elderly patients. In patients with underlying medical conditions, close monitoring of their specific condition is also advised.
