Amantadine

Amantadine is a medication that helps treat Parkinson’s disease by increasing certain brain chemicals, improving movement and reducing tremors. It also has antiviral properties, used to prevent and treat influenza A by blocking the virus from entering cells. Originally developed in the 1960s, it works by boosting dopamine activity in the brain and interfering with virus reproduction. While useful, it can cause side effects like dizziness or nausea, and its effectiveness may diminish over time. It is typically prescribed under medical supervision for specific neurological or viral conditions.
