Amantadine is used to prevent and treat respiratory infection caused by influenza A virus. It is also used in treating abnormalities of movements such as uncontrolled shaking, slow movements, muscle stiffness associated with Parkinson’s disease or drug induced and in the treatment of severe and painful shingles (painful rashes usually in the form of a strip of blisters caused by herpes zoster virus).
How it works
Amantadine belongs to the family of medications called antivirals. It works as an antiviral drug by blocking the reproduction of virus (viral replication) in the body. It also blocks activity of proteins called ‘NMDA glutamate receptors’ in the brain, thereby inhibiting the generation of abnormal movements of Parkinson’s disease.
