Pharmacotherapeutic group

Immunomodulator and biostimulant.

Composition of the preparation

A bottle contains 10 mg of Thymalinum.

Pharmacological action


Thymalinum stimulates cellular immunity (regulates the quantity and correlation of T- and B-lymphocytes, stimulates reactions of cellular immunity), increases phagocytosis, processes of regeneration and hemopoiesis in case of their depression.


There is no detailed description. Effective in parenteral use. When using perorally, it is inactivated in gastrointestinal tract quickly.


The drug is prescribed for the treatment of bronchitis, pneumonia, pleurisy, subacute bacterial endocarditis. Used in actinomycosis, gingivitis, stomatitis, otitis media, pharingitis, sinusitis, purulent meningitis, cholecystitis, angina, scarlatina, pertussis, bacterial and amebic dysentery, brucellosis, tularemia, epidemic typhus and relapsing fever psittacosis, gonorrhea, syphilis, in infectious diseases of genitourinary tracts, skin and tissues infections, and other infectious diseases caused by microorganisms that are sensitive to this antibiotic. Tetracycline may be used for the prevention of infectious complications in surgical patients.

Dosage and method of administration

Contents of the bottle should be diluted in 1-2 ml of isotonic sodium chloride solution and mixed shaking slightly avoiding foaming to obtain even suspension.

Should be injected deep intramuscularly (avoid getting into blood vessels).For adults the drug is prescribed as 0,005—0,02 g (5—20 mg) daily (0,03—0,1 g for a course). For children under one year of age the drug is recommended to be injected as 0,001 g (1 mg), aged 1 to 3 years — 0,001—0,002 g (1—2 mg), aged 4 to 6 years — 0,002—0,003 g (2—3 mg), aged 7 to 14 years — 0,003—0,005 g (3—5 mg) for 3—10 days depending on disorder expression of immunity.

Cases of overdosage have not been described.

In animal experiments chronic injecting in high doses causes involution of thymus.

safety measures
