I've read that it's important not to confuse Rasagiline as a generic for Azilect, but all the information I've found about Rasagiline states that it is used to treat PD. My first question is, did Azilect take Rasagiline's place as a 'new and improved' form of the drug when it was released? My second question is, if both medications are used to treat the same PD symptoms, what are the downsides to using Rasagiline instead of Azilect?
