What is the mechanism of action of rimantadine?
Amantadine and rimantadine are cyclic amines used in the treatment of influenza virus infection. The mechanism of action of these drugs involves inhibiting the uncoating of viral RNA in infected cells and thus effectively preventing viral replication.
