A-fib, stroke prophylaxis: arixtra works diff from warfarin, no approval by fda & no studies establishing its effectiveness. how can it be acceptable?

Arixtra: It is different and it is an anti clotting drug that is effective. Discuss with the doctor why it is being chosen. We do use it when the situation is appropriate.

Agree with you: Arixta is effective in for venous blood clots. It works faster than warfarin but has to be injected, so it is given temporarily. Sometimes it is selected bec of a Heparin allergy. For atrial fibrillation, there are 3 new pills (pradaxa, xarelto, eliquis) that can be used instead of warfarin. They are very attractive because they dont require monthly blood test monitoring.
