What is Saccharomyces Boulardii CNCM I-745?
Saccharomyces Boulardii CNCM I-745 is a specific strain of yeast that is used as a probiotic. It is also known by its brand name Enterol 250 mg[1]. This probiotic is classified as an antidiarrheal medication and is used to help maintain a healthy balance of bacteria in your gut, especially when you’re taking antibiotics[1].
How It Works
When you take antibiotics, they can kill both harmful and beneficial bacteria in your gut. This can disrupt your normal gut flora, potentially leading to digestive issues. Saccharomyces Boulardii CNCM I-745 works by:
- Helping to maintain a healthy balance of microorganisms in your intestines
- Supporting your gut’s natural defense mechanisms
- Potentially reducing the risk of antibiotic-associated diarrhea (AAD)
This probiotic is particularly useful for patients who are undergoing antibiotic therapy, such as those being treated for erythema migrans, which is an early skin manifestation of Lyme disease[1].
Benefits for Patients on Antibiotic Therapy
Research suggests that Saccharomyces Boulardii CNCM I-745 may offer several benefits for patients taking antibiotics:
- Prevention of antibiotic-associated diarrhea (AAD): It may help reduce the likelihood of developing diarrhea as a side effect of antibiotic use[1].
- Improved stool consistency: The probiotic may help maintain normal stool consistency during antibiotic treatment[1].
- Protection of gut microbiota: It may help preserve the diversity of beneficial bacteria in your gut, which can be affected by antibiotics[1].
- Reduction of gastrointestinal symptoms: It may help alleviate other digestive symptoms that can occur during antibiotic treatment[1].
Usage and Dosage
Based on the clinical trial information, the typical dosage of Saccharomyces Boulardii CNCM I-745 is:
- 500 mg twice daily (1000 mg total per day)
- Taken for 21 days, starting at the same time as antibiotic treatment
It’s important to note that this dosage is specific to the clinical trial and may differ from general usage guidelines. Always follow your healthcare provider’s instructions or the directions on the product label[1].
Safety and Side Effects
Saccharomyces Boulardii CNCM I-745 is generally considered safe for most people. However, as with any medication or supplement, there are some precautions to be aware of:
- It should not be used by people with known hypersensitivity to yeast products
- It’s not recommended for people with severe liver or kidney problems
- It should be used with caution in immunocompromised individuals or those with central venous catheters
The clinical trial is also assessing the safety and tolerability of this probiotic, which will provide more information about potential side effects[1].
Ongoing Research
A clinical trial (SUBLYME) is currently underway to further investigate the effects of Saccharomyces Boulardii CNCM I-745 in patients receiving antibiotic therapy for early Lyme disease. The study aims to:
- Assess how the probiotic affects gut microbiota during antibiotic treatment
- Evaluate its effectiveness in preventing antibiotic-associated diarrhea
- Examine its impact on stool consistency and other gastrointestinal symptoms
- Investigate its effects on the gut’s resistance to harmful bacteria (gut resistome)
This research will provide valuable insights into the benefits of using Saccharomyces Boulardii CNCM I-745 alongside antibiotic treatment, particularly for patients with early Lyme disease[1].
