Usage
Lactobacillus Plantarum is a probiotic bacterium used to support digestive health and treat or prevent certain medical conditions. Its pharmacological classification is as a probiotic, which falls under the broader category of biotherapeutics. It exerts its therapeutic effects primarily by modifying the gut microbiota, competing with pathogenic bacteria, enhancing intestinal barrier function, and modulating immune responses. It’s used for conditions such as diarrhea (especially antibiotic-associated diarrhea), irritable bowel syndrome (IBS), atopic dermatitis (eczema), and other inflammatory conditions. It may also aid in nutrient absorption and enhance overall gut health. It is also studied to enhance immunity and alleviate cadmium excretion.
Alternate Names
While Lactobacillus plantarum is the official scientific name, variations like L. plantarum are frequently used. This species has been used in various commercially available probiotic products. It’s important to consult medical literature for a complete list of brands utilizing L. plantarum, as the availability of products changes frequently.
How It Works
Pharmacodynamics: L. plantarum produces lactic acid, which lowers the pH of the gastrointestinal tract, inhibiting the growth of many pathogenic bacteria. It also competes with harmful bacteria for resources and adhesion sites within the gut. The bacteria produce bacteriocins, which are antimicrobial peptides effective against certain pathogenic species. It also enhances the intestinal barrier function, reducing “leaky gut,” and modulates both innate and adaptive immune responses, contributing to anti-inflammatory effects.
Pharmacokinetics: Orally administered L. plantarum primarily resides within the gastrointestinal tract, colonizing the intestines and transiently interacting with the gut immune system. It doesn’t typically enter systemic circulation at significant levels. It’s eliminated through the feces. While it can adhere to the intestinal wall, it doesn’t typically accumulate within the body and is generally considered safe. Metabolism and specific enzyme interactions are less relevant for this probiotic compared to conventional drugs.
Dosage
Standard Dosage
Children: Pediatric dosing of L. plantarum should be determined in consultation with a pediatrician. Dosing considerations for children are usually based on age, weight, and the specific health condition being addressed. The safety and efficacy of L. plantarum in children have been established in various clinical trials but specific recommendations should always be made by a healthcare professional.
Special Cases:
- Elderly Patients: Similar dosage to adults, however monitoring for gastrointestinal tolerance and potential interactions with existing medications is recommended.
- Patients with Renal Impairment: Dosage adjustment isn’t typically necessary, as L. plantarum acts locally in the gut and has limited systemic absorption.
- Patients with Hepatic Dysfunction: No specific dosage adjustments are generally required.
- Patients with Comorbid Conditions: Dosage should be individualized based on the specific condition and potential drug interactions. Consultation with a healthcare provider is crucial.
Clinical Use Cases
Dosage for specific clinical use cases such as intubation, surgical procedures, mechanical ventilation, ICU use, and emergency situations has not been established in standard guidelines. Probiotics are usually not recommended for critically ill individuals except under specific circumstances and with the careful supervision of a physician.
Dosage Adjustments
Dosage modifications might be necessary based on individual responses, tolerance, and the specific product used. Monitoring for potential side effects and efficacy is important to optimize dosing.
Side Effects
Common Side Effects:
Mild and transient gastrointestinal symptoms like gas, bloating, or abdominal discomfort can sometimes occur.
Rare but Serious Side Effects:
In rare cases, especially in immunocompromised individuals, L. plantarum may cause infections like bacteremia or endocarditis.
Long-Term Effects:
Long-term effects are generally minimal as the bacteria do not colonize permanently. However, long-term use is usually well-tolerated and may positively impact gut microbiota composition and overall health.
Adverse Drug Reactions (ADR): Serious adverse reactions are uncommon. Any signs of infection should be promptly evaluated and addressed.
Contraindications
Individuals with severe immune deficiency or those with central venous catheters should use L. plantarum cautiously, as it carries a theoretical risk of infection in these populations.
Drug Interactions
Clinically significant drug interactions are rare. Concomitant use of antibiotics could theoretically reduce the efficacy of L. plantarum. Other drug interactions are not typically considered significant.
Pregnancy and Breastfeeding
L. plantarum is generally considered safe during pregnancy and breastfeeding. However, consulting with a healthcare provider before use during these periods is recommended. Studies have shown no adverse effects on pregnancy outcomes or infant development.
Drug Profile Summary
- Mechanism of Action: Modifies gut microbiota, competes with pathogens, supports intestinal barrier function, modulates immunity.
- Side Effects: Generally well-tolerated; mild gastrointestinal issues may occur.
- Contraindications: Severe immune deficiency, central venous catheters.
- Drug Interactions: Limited clinical significance; antibiotics may reduce effectiveness.
