Amantadine Has Lasting Benefit on Levodopa-Induced Dyskinesia. For patients with Parkinson's disease (PD) who have levodopa-induced dyskinesia (LID), amantadine can maintain its antidyskinetic effect over several years, a new study indicates.
How Does Amantadine Work? Amantadine may work for the flu by inhibiting the uncoating of the flu virus, an important step in the replication (the reproduction) of the virus. Specifically, it inhibits the activity of the influenza virus M2 protein, which forms a channel in the virus membrane.
