to Azilect

Dear Friend,

The FDA requires that the medication rasagiline (Azilect) carry a warning 
with regard to high-tyramine foods. The following study indicates that this 
may not be a concern for people using 1 mg per day. If you use Azilect, I 
recommend you discuss this with your physician. Best, Kathrynne

Safety and tolerability of tyramine challenge in levodopa-treated 
Parkinson's disease patients receiving rasagiline

JR Wilkinson, S Reichwein, MB Stern

High dietary tyramine is safe for PD patients on 1 mg daily rasagiline, 
according to this study.

Twenty patients were randomized to receive rasagiline at 1 mg or 2 mg daily, 
or placebo, for 10 weeks. Patients were free of uncontrolled hypertension, 
cardiovascular disease, and history of stroke. Mean duration of PD was 
approximately 5 years, ranging from 0 to 16 years. All patients were taking 
levodopa.

Patients received 5 tyramine challenges: 75 mg 7 days before commencing 
rasagiline; 25, 50, and then 75 mg on days 22-24 respectively; and then 75 
mg again at the end of the study. Blood pressure monitoring was conducted 
during the challenges and at home over the course of the study. A 
significant response to tyramine was defined as systolic BP >180 mm, or a 
rise >30 mm; diastolic BP >105 mm or a rise >20 mm; or a heart rate >120 bpm 
or a rise >20 bpm.

No patient receiving 1 mg/day rasagiline experienced a significant response 
to any tyramine challenge. Two patients receiving 2 mg/day experienced 
significant responses, neither of whom displayed clinical manifestations:

Patient 1: 25 mg tyramine increased BP from 156/99 to approximately 185/100, 
which returned to normal without intervention after 15 minutes. In the same 
patient, 50 mg tyramine induced a larger response which returned to normal 
after 40 minutes. No further tyramine challenges were performed in this 
patient.

Patient 2: 75 mg tyramine on day 24 increased BP from 137/89 to 168/85, and 
on day 75 from 146/81 to 191/108, both times returning to normal without 
intervention.

Posted: Tue Jun 17, 2008 6:30 pm    Post subject: Azilect and High Blood 
Pressure

You mentioned that some patients had reported high blood pressure after 
taking Azilect. I just started and after titrating up from 0.5mg to 1 
mg...my normally low BP (117/68) shot up to 144/84 and I had irregular 
tachycardia. I read on line some people were sensitive to the caffeine in 
chocolate (I do not drink coffee)

So I cut out ALL caffeine (tea, coffee, candy, etc) and BP went to 124/74 
(still high) and no more tachycardia---this seems consistent with some other 
posts. I have always been sensitive to caffeine. Azilect seems to exaggerate 
it.

Thank you for posting this information. That is a very good point--some 
people are acutely sensitive to caffeine, even in very small amounts. The 
fact that omitting all forms of caffeine has helped you lower your blood 
pressure and relieve tachycardia is an important point, as it allows you to 
benefit from continued use of Azilect. Thank you for posting!
