angina
"Have been taking this drug for over five years.  Had a great drug plan so the $50.00 for a 90 day supply didn't bother me even though I never thought that the drug did anything.  Have had two heart bypass surgeries and four stents placed in my coronary arteries in the past 20 years.  Cardiologist prescribed this drug cause he ran out of options for my angina.  Like I said, never did anything.  Recently I lost my good drug plan and now my new Part 'D' prescription drug plan has me paying $225.00 per month for this drug........ridiculous.  The manufacturer offers discounts on line which is just another 'rip'.  Their own product literature says that 'we don't really understand how it works'.....well guess what; it doesn't.  This drug is a scam"
