Pharmacological properties
Pharmacodynamics
Poludane is a biosynthetic polyribonucleotide complex of polyribouridylic and polyriboadenylic acids. Inductor of biosynthesis of endogenous interferon and other cytokines.
It has a pronounced immunomodulatory and antiviral activity. Promotes an increase in the activity of natural killer cells, which are initially reduced in patients with ophthalmic herpes, as well as other immunocompetent cells.
When injected, the production of endogenous interferon in blood serum and tear fluid is stimulated. It is determined 3 hours after drug administration. A high level of interferon (110 and 75 U / ml in blood and lacrimal fluid, respectively) is maintained with daily administration throughout the entire course of use. The next day after discontinuation of therapy, the substance is practically not detected (titer - not higher than 10 U / ml).
