I was talking to a doctor who specializes in the treatment of A-Fib about six months ago. He was very excited by the prospects of using Eliquis with his patients when it was approved. He didn't come out and directly say it, but I don't think he was real thrilled with Pradaxa. I believe Eliquis proved safer and more effective than Warfarin, and that appears to put it in a class by itself. Good to be long! IMHO.
