Amantadine is a drug prescribed to control movement problems in certain conditions. It increases the amount of dopamine in the blood hence, controls movements. The class of drugs which it belongs to is known as adamantine.


The drug amantadine is used as a treatment option for controlling involuntary muscular movements in the patients of Parkinson’s disease. Previously, it was used to treat type A influenza, but now it is only prescribed for curing movement disorders.
The reason behind its ban as a medication for type a influenza is a widespread drug rejection in populations.
