Amantadine is a medicine used to manage stiff muscles and movement. Acting on chemical messengers, Amantadine improves signal flow throughout the central nervous system.
Amantadine is an adamantane-derived compound that belongs to a class of antivirals and dopaminergic agents. It is the active ingredient in products marketed under the name Amantadine.
Amantadine works by interfering with certain viruses and by influencing brain chemistry that controls movement.
Amantadine is used to help prevent a specific type of influenza and to ease Parkinson-related symptoms such as shaky hands, stiffness, or slow movements. It can also be given to manage unwanted muscle tremors caused by certain medications. Some patients find it helpful for fatigue following viral infections.
Amantadine blocks the step that allows a virus to release its genetic material inside a cell, slowing the spread of the virus. In the brain, it prolongs the activity of the natural chemical dopamine, which helps smooth out shaky movements.
Pregnant or nursing people need to be cautious about amantadine. People with severe kidney problems, a history of heart rhythm issues, or seizures should discuss use with a healthcare professional. Certain substances can change how amantadine works, such as alcohol, some antiviral medicines, and drugs that affect dopamine.
Check the label of your specific product for a complete list of possible interactions.
Older adults and people with reduced kidney function tend to notice side effects more often. Those taking multiple medicines that affect dopamine may also experience stronger reactions.
Keep amantadine tablets in a dry place away from direct sunlight and store them at room temperature. The medicine may be taken for a short period to prevent flu or for longer periods when managing movement issues, depending on the product you have. Different brands of Amantadine can vary in strength, so always follow the instructions that come with your specific medication.
For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
