(Amantadine Hydrochloride)

The active ingredient in Symmetrel is amantadine hydrochloride.

Amantadine works through multiple mechanisms of action in the central nervous system. It helps increase dopamine release and block its reuptake, which improves communication between nerve cells and helps reduce symptoms of Parkinson’s disease such as stiffness and slowed movement. It also has mild anticholinergic effects that support movement control. For antiviral activity, amantadine interferes with the replication of the influenza A virus by blocking viral uncoating inside cells.
