Amantadine treats parkinsonian dyskinesia as an muscarinic antagonist and acts as a noncompetitive NMDA antagonist. Amantadine was used as an antiviral drug used to treat and prevent influenza A infections. The antiviral mechanism of action is antagonism of the influenza A surface protein M2. M2 inhibition prevents viral shedding. Due to high levels of viral resistance to amantadine and other adamantanes, these drugs are no longer used against influenza A virus.
