Active ingredient and dosage form

1 g of ointment contains human Interferon recombinant alpha-2b 40,000 IU;

Mechanism of action

The preparation of human recombinant interferon alfa-2b.
It has antiviral, immunomodulatory and antiproliferative effects. Under the influence of interferon in the body, the activity of natural killer cells, T-helper cells, cytotoxic T-lymphocytes, phagocytic activity, B-lymphocyte differentiation intensity, and expression of MHC type I and II antigens increase.
The drug also directly inhibits the replication and transcription of viruses, chlamydia.
Damage to cell membranes, observed during the development of an infectious process, is the reason for the decrease in the antiviral activity of interferon. Tocopherol acetate and Ascorbic acid, which are part of the drug Viferon, are membrane-stabilizing components, antioxidants, in combination with which the antiviral activity of recombinant interferon alpha-2b increases 10-14 times. In addition, the immunomodulatory effect of interferon on T- and B-lymphocytes is enhanced, the content of immunoglobulin E is normalized, there are no side effects (fever, fever, influenza-like phenomena) arising from the parenteral administration of interferon preparations.
It has been established that when using Viferon for 2 years, antibodies that neutralize the antiviral activity of recombinant interferon alpha-2b are not formed.
The use of the drug Viferon can significantly reduce the course dose and the duration of courses of treatment with antibiotics, hormones and cytotoxic drugs.
Features of the introduction of the dosage form provide long-term circulation in the blood of interferon alfa-2b.

12 h after rectal administration of Viferon, a decrease in the level of interferon in the blood serum is observed, which necessitates its repeated administration.
