Thymalin is a polypeptide medicine containing extract of cattle thymus in proportion 10 mg per bottle.

This medication induces proliferation and differentiation of T lymphocytes (Thymus-dependent lymphocytes) precursors into mature T cells, stabilises the T lymphocyte subpopulations ratio, regulates the T and B lymphocyte interaction and activates phagocytic function in neutrophils, microphages, monocytes and NK cells (Natural-killer cells).


  • as a part of complex therapy of bacterial and chlamydia infections (in gynaecology and urology);
  • as a part of complex therapy of acute and chronic inflammatory infections that are accompanied by impairment of cellular immunity (treatment of osteomyelitis, prostatitis, etc.);
  • for preventing the suppression of immunity, hematogenesis and regeneration processes in the post-traumatic and post-operative period (treatment of full-thickness burns and frostbites);
  • during radiotherapy or chemotherapy treatment and while taking massive doses of antibiotics (in oncology);
  • for prevention and complex treatment of viral infections, including URI (upper respiratory infection) and influenza (treating children with frequent and long-term illnesses).

The medication stabilises the immune response and regulates the T and B cell ratio. Thymalin has a broader application scope. It can be used in case of immunosuppression of any origin and is compatible with antiviral medication. Thymalin produces a mild, natural physiological immunological effect without disturbing (over-stimulating) the immune response. The regeneration enhancement (the second component of the action of Thymalin) provides for better healing time with no side effects.

Thymus mediciations can be used as monotherapy in children with frequent ARVI (acute respiratory viral infections), especially in children with a history of thymomegaly (thymic hyperplasia).
Long-term results (up to 17 years of observation) of treatment with thymus mediciations indicate their protective effect. None of the children during the follow-up period (for 17 years) had repeated pneumonia, relapses of osteomyelitis, sepsis, candidiasis of the skin and mucous membranes, candidal meningitis or infective endocarditis.

The use of Thymalin can significantly reduce the frequency of metastasis of malignant tumors by 2.3 times.

Pharmacological effect

This medication restores the immune reactivity (by regulating the ratio and interaction of T and B lymphocytes and the subpopulations thereof, stimulating the cellular immunity and enhancing the phagocytosis), prevents the suppression of regeneration and hematogenesis and enhances cell metabolism.

Application and dosage

Dilute the content of one bottle in 1-2 ml of isotonic solution of sodium chloride before injection. The medication is applied intramuscularly daily: dosage for adults is 5-20 mg (a course of 30-100 mg), for infants under 1 year - 1 mg; for 1-3 year olds - 1.5-2 mg; for 4-6 year olds - 2-3 mg; for 7-14 year olds - 3-5 mg over 3-10 days. If necessary, the treatments can be repeated after 1-6 month. As a prevention, the medication is applied intramuscularly daily, adults 5-10 mg, children 1-5 mg over 3-5 days.
