The pharmacological effect of the drug Genferon Light is due to the presence of alfa-2b and taurine in the composition of interferon. They have the following properties:
- immunomodulatory effect (harmonization of the functions of immunity);

- antiproliferative effect (inhibition of the multiplication of bacteria and cancer cells);
- immunostimulating effect (improving the efficiency of the immune system);
- indirect antimicrobial action;
- anti-inflammatory effect.
Pharmacodynamics and pharmacokinetics
The main active ingredient of Genferon Light is interferon alfa-2b. It is obtained by modifying bacteria Escherichia coli using genetic engineering.
Interferon is able to indirectly affect intracellular pathogens (chlamydia and viruses), changing the metabolism of the cell and stopping their intracellular replication and further spread. Interferon also affects neighboring cells, initiating reactions leading to inhibition of viral protein production. The effect of interferon on neighboring cells is an increase in the synthesis of substances that reduce protein synthesis. This mechanism is detrimental to the virus, because blocks its further reproduction. In addition, interferon activates a number of genes that play an important role in the antiviral defense of the cell and triggers the death mechanism of the infected cell.
Another direction of action of interferon is activation immunity. The result of this activation is a more effective fight of cells of the immune system (T-killers, phagocytes and T-helpers) with viruses and bacteria.
Taurine improves the metabolism of individual cells and tissues in general, stimulates reparative (restoration) processes. It improves and stabilizes the structure of cell membranes. Taurine is an antioxidant - interacting with active oxygen compounds in the body, it prevents tissue damage by these compounds.
For rectal use of the drug is characteristic bioavailabilityreaching 80% or more, which is associated with pronounced local and complex immunomodulatory effect. Vaginal administration is characterized by a pronounced local (a high concentration of the drug in the pathological focus is achieved) and a slight systemic effect (the drug practically does not penetrate the bloodstream through the mucous membranes of the internal genital organs). The result is a pronounced local antiviral, antiproliferative and antibacterial effects.
Interferon reaches its maximum concentration in the blood 4-6 hours after administration. It is excreted mainly by the kidneys. The elimination half-life is about 12 hours, the result of which is the need for a double preparation during the day.
Intranasal use is characterized by pronounced immunostimulating and antiviral effect (due to the large concentration in the pathological focus). The drug’s entry into the bloodstream during this route of administration does not reach large values due to the special molecular structure of the membranes of the mucous membranes of the nasopharynx. However, a certain amount of interferon still enters the bloodstream, causing complex immunomodulatory effect.
