What is the difference? >> Eldepryl is the trade name and Selegiline is the generic (chemical name) in the name in the United States Pharmacopeia (USP), the official compendium for the US. It appeared in Canada as Deprenyl before it was introduced in the States. The provinces in Canada use both the USP and the British Pharmacoeia and probably the European Pharmacopeia. One study did indeed report a relationship of the use of selegiline and mortality. Just make sure you have a competent neurologist specializing in movement disorders and that you discuss your own case, and then heed his/her advice. Be weller and carpe Diem Michel Margosis
