MS-1610

A 67-year-old male patient visits the neurology clinic for a routine follow-up of his Parkinson’s disease, which he has been diagnosed with for a few years now. Despite trying various medications, the patient’s symptoms have been progressively deteriorating. The neurologist decides to add amantadine to his treatment regimen, in addition to other medications. Apart from its dopaminergic effects, the drug also possesses antiviral properties.

What is the mechanism of action of amantadine’s antiviral activity?
