>From the book "Parkinson's Disease- The Complete Guide for Patients and Caregivers" by Lieberman and William, pg 59-60... Another drug commonly prerscribed early in PD treatment is Amantadine, also known as Symmetrel. [.. history...] Further research confirmed the research and amantadine became a common anitparkinsoniand drug in the late 1960s. Exactly how amantadine works on the parkinsonian brain remains unclear. It appears to help release dopamine from within the remaiing substantia nigra cells, thereby stimulating the activity of the striatum. [... side effects discussion..] Nevertheless, for many mild cases of PD, Symmetrel works quite well to reduce symptoms, including tremor, rididity, and bradykinesia. Like anticholinergic therapy, Symmetrel may often delay for several months or more, the need for levodopa therapy. It may also be used in conjunction with other anti-PD drugs as the disease progresses. On a personal note, I've been taking Amantadine and Eldepryl for about a year. Its given some benefit but isn't a world class solution. No side effects that I can tell.

Info Date: Tuesday, April 29, 1997 10:21PM I'm looking for more information on Amantadine, a new drug that is supposed to reduce dyskenesias - and other adverse side-effects of levodopa (Sinemet). Patients & physicians comments who have direct knowledge of the drug especially appreciated. Thanks - Kent in LA
