Pharmacological properties
Immunobiological and biological properties
The drug has the ability to specifically lyse bacteria such as Streptococcus pyogenes, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Proteus mirabilis. Bacteriophages specifically infect bacterial cells, multiply inside the bacterial cell and destroy it by lysis. The antibacterial effect of the drug is due to the specific lysis of pathogenic bacteria, while the drug does not disrupt the state of normal microflora. Under the action of the bacteriophage, phagocytosis is activated, the activity of neutrophils and their metabolic activity increases, which prevents the recurrence of an infectious disease and the chronicity of the inflammatory process. The number of leukocytes and neutrophils decreases, and the level of lymphocytes increases mainly due to T-lymphocytes. Bacteriophages penetrate the blood and lymph for a short time and are excreted by the kidneys with urine.
Indication
Treatment and prevention of purulent-inflammatory and intestinal diseases caused by staphylococci, streptococci, Pseudomonas aeruginosa, pathogenic Escherichia coli of various serogroups, Proteus. The drug is used as monotherapy or as part of combination therapy.
Contraindication
Hypersensitivity to the components of the drug.
Interaction with other medicinal products and other types of interactions
The drug can be used in combination with other antibacterial agents, as well as monotherapy - if the patient is intolerant to antibiotic therapy, if the strains of the pathogen are resistant to antibiotics.
Application features
An important condition for effective phage therapy is the preliminary determination of the phage sensitivity of the pathogen. The drug should be started as early as possible. The drug should not be used if the solution is cloudy.
Ability to influence reaction speed when driving vehicles or other mechanisms
The use of the drug does not affect the reaction speed when driving vehicles or other mechanisms.
Use during pregnancy or breastfeeding
Safety and efficacy have not been established, so use is contraindicated.
Method of administration and doses
Treatment of purulent-inflammatory diseases with localized lesions should be carried out simultaneously both topically and orally. Duration of treatment is 7–20 days.
When dosing the drug, follow the instructions for medical use. In the case of using small doses (2–8 drops), the drug must be drawn up with a sterile syringe with a volume of 0.5–1 ml or use a spray nozzle. 1 milliliter of the drug contains 20 drops of bacteriophage solution, 1 injection with a spray nozzle contains 0.2 ml of solution.
Locally used in the form of irrigation, lotions and tamponade with liquid phage in an amount of up to 200 ml depending on the size of the affected area. In case of abscesses, the bacteriophage is injected into the cavity of the focus after removing the pus by puncture. The amount of the drug injected should be slightly less than the volume of the removed pus. In case of osteomyelitis, after appropriate surgical treatment, the bacteriophage is infused into the wound in an amount of 10–20 ml.
Introduction into cavities – pleural, articular and other limited cavities – up to 100 ml of bacteriophage, after which capillary drainage is left, through which the bacteriophage is re-injected within several days.
In case of cystitis, pyelonephritis, urethritis, the drug is taken orally. If the cavities of the bladder or renal pelvis are drained, the bacteriophage is administered through a cystostomy or nephrostomy 1–2 times a day, 20–50 ml into the bladder and 5–7 ml into the renal pelvis.
For purulent-inflammatory gynecological diseases, the drug is injected into the vaginal cavity and uterus in a dose of 5–10 ml once daily.
For purulent-inflammatory diseases of the ear (otitis), throat (sore throat), nose, the drug is administered in a dose of 2–10 ml 1–3 times a day. The bacteriophage is used for rinsing, washing, instillation, and wetting turundas (which are administered and left for 1 hour).
For conjunctivitis and keratoconjunctivitis, the drug is instilled 2–3 drops 4–5 times a day, for purulent corneal ulcers – 4–5 drops, for purulent iridocyclitis, the drug is used 6–8 drops every 3 hours in combination with oral administration.
In intestinal forms of the disease, diseases of internal organs, dysbacteriosis, the drug is used orally and in an enema. Orally, the bacteriophage is taken 3 times a day on an empty stomach, 1 hour before meals.
The recommended dosage of the drug is given in Table 1.
Table 1
| Age | Dose per 1 dose (ml) |
| internally |
| Up to 6 months | 5 |
| From 6 to 12 months | 10 |
| From 1 to 3 years | 15 |
| From 3 to 8 years old | 20 |
| From 8 years old | 30 |
The use of bacteriophages does not exclude the use of other antibacterial drugs. If chemical antiseptics were used to treat wounds before using bacteriophages, the wound should be thoroughly washed with sterile 0.9% sodium chloride solution.
In intestinal forms of the disease, rectal administration of the bacteriophage is possible – once a day, in the form of an enema after emptying the bowels instead of 1 oral dose.
The recommended dosage of the drug when administered rectally is listed in Table 2.

| Age | Dose per 1 dose (ml) |
| rectally |
| Up to 6 months | 10 |
| From 6 to 12 months | 20 |
| From 1 to 3 years | 30 |
| From 3 to 8 years old | 40 |
| From 8 years old | 50 |
