Pharmacological properties
This drug belongs to the group of antiviral drugs – rimantadines, used systemically.
The main active component of the drug, rimantadine hydrochloride, is an amantadine derivative. Has a pronounced antiviral activity.
Rimantadin has an effect on different A-type virus strains, including the main three – H1N1, H2N2, H3N3 – types.
In addition, it also has an antitoxic effect on influenza viruses caused by the B-type virus.
It is able to inhibit the ability of the virus to reproduce (replicate), especially the antiviral effect is high in the early stages, when the virus has not yet multiplied to a critical amount. The mechanism is the ability to disrupt the formation of the envelope of the virus.
As shown by genetic studies, when using rimantadin, the latter does not affect the immunogenic effect when a vaccine (inactivated) is administered, which prevents the development of the A-type virus.
