Both drugs are some what the same, they both work by keeping your blood platelets from sticking together and forming clots. Plavix is a adenosine diphosphate (ADP) receptor and Pradaxa is a direct thrombin inhibitor. Both do basically the same thing just in different ways. Pradaxa is normally used in the treatment of blood clots due to A-fib or other rhythm issues when there is no heart valve disease and Plavix is a stronger drug used to help prevent clots in the arteries primarily after heart surgery.
Both are good drugs and either should work from what I understand.
Hope this helps,

In my understanding both prevent blood clots.Based on that :yes it was a good choice.
