Amantadine

Amantadine is an antiviral and antiparkinsonian medication used primarily to treat and prevent influenza A infections and manage symptoms of Parkinson's disease and drug-induced extrapyramidal reactions. It helps to reduce symptoms such as tremors, stiffness, and bradykinesia by increasing dopamine release in the brain. Additionally, it may assist in alleviating fatigue associated with multiple sclerosis. Its dual action makes it a versatile drug in managing neurological and viral conditions.
