Pharmacological action of

Altevir has antiviral, immunomodulating, antiproliferative and antitumor effects. Interferon alfa-2b, interacting with specific receptors on the cell surface, it initiates a complex chain of changes within the cell, including the induction of the synthesis of a number of specific cytokines and enzymes, disrupts the synthesis of viral RNA and virus proteins in the cell. The result of these changes is nonspecific antiviral and antiproliferative activity associated with the prevention of virus replication in the cell, inhibition of cell proliferation and the immunomodulatory effect of interferon. Interferon alpha-2b stimulates the process of antigen presentation to immunocompetent cells, has the ability to stimulate the phagocytic activity of macrophages, as well as the cytotoxic activity of T cells and “natural killers” involved in antiviral immunity. It prevents the proliferation of cells, especially tumor cells. It has a depressing effect on the synthesis of certain oncogenes, leading to inhibition of tumor growth.

Indications

Altevir is used in complex therapy in adults: in case of chronic viral hepatitis B without signs of liver cirrhosis,

in case of chronic viral hepatitis C in the absence of signs of liver failure (monotherapy or combination therapy with ribavirin),

in case of papillomatosis, condylomatosis

for hairy cell leukemia, chronic myelogenous leukemia, non-Hodgkin’s lymphoma, melanoma, multiple myeloma, Kaposi’s sarcoma with AIDS, progressive kidney cancer.

Special instructions

Before treatment with chronic viral hepatitis B and C by Altevir, a liver biopsy is recommended to evaluate the degree of liver damage (signs of an active inflammatory process and / or fibrosis). The effectiveness of treatment for chronic hepatitis C increases with combination therapy with Altevir and ribavirin. The use of Altevir is not effective in the development of decompensated cirrhosis of the liver or hepatic coma.

In case of side effects during treatment with Altevir, the dose should be reduced by 50% or the drug should be temporarily discontinued until they disappear. If side effects persist or occur again after a dose reduction, or disease progression is observed, then treatment with Altevir should be discontinued.

With a decrease in platelet count below 50x109 / L or granulocyte level below 0.75x109 / L, a 2-fold reduction in the dose of Altevir is recommended with a blood test after 1 week. If these changes are saved, Altevir should be discarded.

With a decrease in platelet count below 25x109 / L or granulocyte level below 0.5x109 / L, it is recommended that Altevir be withdrawn with a blood test after 1 week.

In patients receiving interferon alfa-2b preparations, antibodies can be detected in the blood serum, antiviral activity neutralizing it. In almost all cases, antibody titers are low, their appearance does not lead to a decrease in the effectiveness of treatment or the occurrence of other autoimmune disorders.
