Novirin composition and form of release
The active ingredient of Novirin is inosine pranobex. Also, the preparation contains excipients: magnesium stearate, povidone, potato starch.
Novirin is produced in the form of tablets (500 mg).
Novirin is an antiviral medicine. Its active substance has a direct antiviral and immunity modulating effect. Its effect is due to the ability to bind to the ribosomes of cells affected by the virus, slowing down the production of viral i-RNA and inhibiting the replication (self-reproduction) of DNA and RNA viruses. It also inhibits the formation of interferons. The immunomodulatory effect is due to its effect on T-lymphocytes and an increase in the absorbing (phagocytic) activity of macrophages. Novirin enhances the differentiation (sorting) of pre-T-lymphocytes, stimulates the multiplication of immune cells (T-, B-lymphocytes), increases the activity of T-lymphocytes, normalizes the ratio between the populations of T-helpers and suppressors ( restores the CD4 / CD8 index). As a result of the complex effect of the drug on immunity, the viral load decreases, the production of immune cells is normalized, the production of its own interferons is activated, contributing to resistance to infections, and the rapid limitation of the focus of infection …
