"It's premature to say that a drug like dabigatran will take the place of warfarin," Gersh added. "There will be a lot of discussion about cost and convenience. It's a twice-daily dose and there are some questions about a possible higher rate of heart attack. I don't think this is truly resolved yet, but I think we can say that for the first time we have seen a drug that certainly has the potential to be an alternative to warfarin, and maybe even superior."
