Pharmacological properties

Tylosin is an antibiotic from the macrolide group, it is active against most gram-positive and some gram-negative bacteria, including staphylococci, streptococci, corynebacteria, clostridia, pasteurella, erysipelotrix, spirochetes, chlamydia, treponema, chiodysentery and mycoplasma. When administered intramuscularly, the antibiotic is well absorbed from the injection site into the bloodstream and penetrates into almost all organs and tissues of the body. The highest levels of tylosin are found in the lungs, liver, mammary glands and kidneys. After a single injection, the therapeutic concentration of the antibiotic remains in the body for at least 20 hours. In addition, due to the peculiarities of the mechanism of action, Farmazin 50 selectively accumulates in tissues with low pH values, that is, in the foci of inflammation, providing a targeted effect. Pharmazin 50 also exhibits nonspecific immunostimulating and immunomodulatory effects due to inhibition of cytokines, activation of plasma cells and antibody production, activation of leukocyte chemotaxis and proliferation of lymphoid elements. Pharmazin 50 in extremely high concentrations accumulates in the lysosomes of neutrophils, ensuring the completeness of phagocytosis and rapid elimination of bacterial pathogens. The special composition of the organic solvent in injection Pharmazin provides high storage stability, optimal consistency for comfortable filling of the syringe and absolutely painless injections for the animal. The drug is excreted from the body mainly in feces, in smaller quantities in urine and milk. activation of plasma cells and production of antibodies, activation of chemotaxis of leukocytes and proliferation of lymphoid elements. Pharmazin 50 in extremely high concentrations accumulates in the lysosomes of neutrophils, ensuring the completeness of phagocytosis and rapid elimination of bacterial pathogens. The special composition of the organic solvent in injection Pharmazin provides high storage stability, optimal consistency for comfortable filling of the syringe and absolutely painless injections for the animal. The drug is excreted from the body mainly in feces, in smaller quantities in urine and milk. activation of plasma cells and production of antibodies, activation of chemotaxis of leukocytes and proliferation of lymphoid elements. Pharmazin 50 in extremely high concentrations accumulates in the lysosomes of neutrophils, ensuring the completeness of phagocytosis and rapid elimination of bacterial pathogens. The special composition of the organic solvent in injection Pharmazin provides high storage stability, optimal consistency for comfortable filling of the syringe and absolutely painless injections for the animal. The drug is excreted from the body mainly in feces, in smaller quantities in urine and milk. ensuring the completeness of phagocytosis and rapid elimination of bacterial pathogens. The special composition of the organic solvent in injection Pharmazin provides high storage stability, optimal consistency for comfortable filling of the syringe and absolutely painless injections for the animal. The drug is excreted from the body mainly in feces, in smaller quantities in urine and milk. ensuring the completeness of phagocytosis and rapid elimination of bacterial pathogens. The special composition of the organic solvent in injection Pharmazin provides high storage stability, optimal consistency for comfortable filling of the syringe and absolutely painless injections for the animal. The drug is excreted from the body mainly in feces, in smaller quantities in urine and milk.
