Usage
Bacillus Clausii is a probiotic primarily used to treat and prevent alterations in the intestinal bacterial flora (dysbiosis). These alterations can occur due to various factors, including:
- Diarrhea: Especially acute diarrhea in children, and diarrhea associated with antibiotic use or chemotherapy.
- Antibiotic-associated diarrhea: It helps restore the balance of gut bacteria disrupted by antibiotics.
- Gastrointestinal disorders: May provide benefits in conditions like small intestine bacterial overgrowth (SIBO), irritable bowel syndrome (IBS), and as an adjunct therapy in Helicobacter pylori eradication.
- Respiratory infections: Some evidence suggests potential benefits in preventing respiratory infections in children, possibly due to its immunomodulatory effects.
Pharmacological Classification: Probiotic
Mechanism of Action: Bacillus Clausii exerts its therapeutic effects through several mechanisms:
- Competitive exclusion: It competes with pathogenic bacteria for resources and adhesion sites in the gut, thus limiting their growth.
- Antimicrobial substance production: Bacillus Clausii produces substances that inhibit the growth of certain harmful bacteria.
- Immunomodulation: It interacts with the gut immune system, enhancing local immune responses and promoting a healthy gut barrier.
- Vitamin production: It synthesizes certain vitamins, particularly B vitamins, helping correct vitamin deficiencies that can occur with antibiotic use.
Alternate Names
- Bacillus subtilis (historically; note that current scientific classification distinguishes Bacillus clausii as a separate species)
Brand Names:
- Enterogermina
- Erceflora
- Progermila
How It Works
Pharmacodynamics: Bacillus Clausii spores, resistant to gastric acid, germinate into metabolically active vegetative cells in the intestine. These cells exert their probiotic actions primarily within the gut lumen, modulating the gut microbiota, enhancing immune responses, and contributing to vitamin synthesis. The resulting restoration of a balanced gut flora helps alleviate symptoms like diarrhea and improves nutrient absorption.
Pharmacokinetics:
- Absorption: Minimal systemic absorption. Primarily acts locally within the gastrointestinal tract.
- Metabolism: Not extensively metabolized in the human body. The spores germinate and produce active cells.
- Elimination: Primarily eliminated in feces, as spores and vegetative cells.
Mode of Action: At the cellular level, Bacillus Clausii produces antimicrobial substances, competes with pathogens for adhesion sites, and stimulates the gut’s immune system.
Dosage
Standard Dosage
Adults:
- 2-3 vials (or capsules containing 2 billion spores each) daily, at 3-4 hour intervals.
Children:
- Infants and children: 1-2 vials (of suspension containing 2 billion spores/5mL) daily, at 3-4 hour intervals.
Special Cases:
Dosage adjustments in elderly patients, those with renal or hepatic impairments, or with comorbid conditions are not specifically defined. It’s crucial to exercise caution and consult with a specialist in these cases for tailored recommendations.
Clinical Use Cases
No specific dosage guidelines exist for these clinical settings: intubation, surgical procedures, mechanical ventilation, ICU use, emergency situations. Probiotic use in such cases should be under careful medical supervision and individualized based on patient needs.
Dosage Adjustments
Dosage adjustments are generally not formally specified, but caution and consultation with a medical specialist are warranted in patients with hepatic/renal dysfunction, metabolic disorders, or genetic polymorphisms.
Side Effects
Common Side Effects:
Generally well-tolerated. Mild gastrointestinal symptoms like bloating and gas may occur.
Rare but Serious Side Effects:
- Hypersensitivity reactions (rash, itching, angioedema, urticaria)
- Bacteremia and sepsis (extremely rare, primarily in severely immunocompromised individuals)
Long-Term Effects:
No known long-term adverse effects have been reported.
Adverse Drug Reactions (ADR):
Severe allergic reactions and bacteremia (in highly susceptible individuals) require immediate medical attention.
Contraindications
- Hypersensitivity to Bacillus Clausii or any component of the formulation.
Drug Interactions
Antibiotics can reduce the efficacy of Bacillus Clausii. It’s advisable to administer Bacillus Clausii between antibiotic doses. No other clinically significant drug interactions are well-documented.
Pregnancy and Breastfeeding
Considered generally safe during pregnancy and breastfeeding. However, consultation with a healthcare provider is recommended before use.
Drug Profile Summary
- Mechanism of Action: Restores gut microbiota balance, produces antimicrobial substances, modulates immunity, synthesizes vitamins.
- Side Effects: Generally well-tolerated. Rare: bloating, gas, hypersensitivity reactions.
- Contraindications: Hypersensitivity.
- Drug Interactions: Antibiotics (reduced efficacy).
- Pregnancy & Breastfeeding: Generally safe; consult a doctor.
- Dosage: Adults: 2-3 vials/capsules daily; Children: 1-2 vials daily.
- Monitoring Parameters: Monitor for resolution of symptoms (e.g., diarrhea), and for any allergic reactions.
Popular Combinations
No specific “popular combinations” exist in the conventional sense. It’s often used alongside oral rehydration solutions in diarrhea treatment.
Precautions
- General Precautions: Assess for any history of allergies.
- Specific Populations: In immunocompromised individuals, especially those with severely weakened immune systems, caution is warranted due to the theoretical risk of bacteremia.
- Lifestyle Considerations: No specific lifestyle restrictions are associated with Bacillus Clausii use.
