Indications and Therapeutic Goals
The main task of probiotics in clinical practice is microbiocenosis correction. These agents help normalize both the qualitative and quantitative composition of the body's microflora.
The primary indication for their use is dysbiosis of various etiologies. Due to the multi-factorial (polyetiological) nature of this condition, dysbiosis is extremely widespread among the population. Factors leading to its development include:
- Previous infectious and somatic diseases.
- Adverse environmental conditions and occupational hazards.
- Secondary immunodeficiency states.
- Irrational and unbalanced nutrition.
Due to high demand, probiotics are mass-produced items supplied continuously through pharmacy networks.
Composition and Formulations
The active principle of probiotics consists of live bacteria. To preserve their viability in the preparation, manufacturing utilizes lyophilization — gentle dehydration of microorganisms via vacuum freezing.
In addition to lyophilized cultures, formulations contain auxiliary components such as various stabilizers and flavoring agents.
Main dosage forms:
- Powders for suspension preparation.
- Tablet forms.
- Dietary analogs — fermented milk products purposely enriched with live normal microflora.
Dosing and Administration Guidelines
Probiotic dosage is always calculated strictly based on the number of live bacterial cells contained in one gram of the substance or in one tablet. The standard therapeutic dose generally ranges from 1 to 100 million live bacteria.
Therapy characteristics:
- Route of administration: Orally (per os).
- Frequency: 2–3 times daily.
- Duration: Restoring microflora takes time, so treatment courses are always prolonged, lasting from 1 to 6 months.
- Combinations: Typically, probiotics are not used in isolation; they are prescribed in rational combination with other therapeutic modalities.
Storage Conditions
The presence of viable microbial cells makes probiotics extremely sensitive to environmental factors.
To maintain drug efficacy, it is critically important to ensure proper storage conditions. Key requirements include strict temperature control (typically refrigeration, per product labeling) and mandatory protection of packaging from direct sunlight.
