^^^^^^WARM GREETINGS FROM^^^^^^^^^^^^^^^^^ Ivan Suzman 48/12/9.5 [log in to unmask] Portland, Maine Land of lighthouses 42 deg. F ******************************************************************** Ida, thank you for explaining how AMANTADINE is effective in treating PD. My neurologist thought it was its anti-viral action, and so did I, but after reading your post, I have come to a new understanding. Now, Ida, do I have this correctly? -- Amantadine IS in fact an antiviral medication, but, its effectiveness in reducing tremor in PD is because it is ALSO a glutamate antagonist, and glutamates inhibit dopamine. In other words, amantadine protects dopamine by blocking glutamates from inhibiting dopamine! Your recent posts are VERY helpful. THANKS, Ida --- and please correct my understanding of amantadine if I am mistaken. Thanks again, IVAN
