My doctor after examining my stress test TMT and eco , concluded some nerrowing in cornary and priscribed my nikondril 5 mg twice with eco esprin AV 150 daily. the mediction i am using since Oct 2010. Whether it a correct or there some risk or side effect of taking it because i am diagonise at EPD ( early parkinson ) in Oct 2009 and since then on the advice of neurologist , I am taking pramirol .75 mg twice instead of 2.25 mg prescribed, 10 mg synodopa plus and 1 mg receticline ( Rasagline) instead of 2mg priscribed.
