Amantadine is used to treat Parkinson's disease, sometimes called paralysis agitans or shaking palsy. It may be given alone or with other medicines for Parkinson's disease. By improving muscle control and reducing stiffness, this medicine allows more normal movements of the body as the disease symptoms are reduced. Amantadine is also used to treat stiffness and shaking caused by certain medicines used to treat nervous, mental, and emotional conditions. Amantadine is sold under the name Symmetrel and Vyregit for use both as an antiviral and an antiparkinsonian drug. Rimantadine is a closely related derivative of adamantane with similar biological properties.
