Amatadine (symmetrel) is an anticholinergic cmpound (often used to treat
flu-like symptoms).  It was not intended for anti-parkinsons treatment and
there is still some question as to why it helps.  I am taking it now to help
control dyskinesia in my left foot.  Cogentin and benadryl are just two of
the many similar drugs.

Selegeline (eldepryl) on the other hand, is a monoamine oxidase inhibitor -
type B  (metabolic enzyme blockade, i.e. the drug reduces the breakdown of
dopamine within the brain). Taken with dopamine, selegeline increases
dopamine efficacy. Selegeline, too, was not created for Parkinson's, but was
originally an anti-depressant.  The jury is still out on whether or not
selegeline offers neuroprotection, but many neurologists suggest it be
taken.

The major drawback with taking an MAO inhibitor is that is interacts
violently with several routinely-administered medications, such as Demerol
(and some foods).  Although I have some medical background, I am not a
professional in medications, but the NPF has some invaluable information on
PD medications at this site  http://www.parkinson.org/med4.htm#intro
beginning on page 5 and following.
