I believe Eliquis, (apaxiban), is the best of these new anticoags.. $6+ per month in Oz. for us. Approx. 5,000 baht p/m here. But if you can't get home every 6 months, India has a generic, called Apigat. Aud $150,with postage, for 3 months supply. Warfarin is a pia. Stop 1 week before surgery, and always problems with clotting levels. So unless they've given you a pig's heart, go with Eliquis. As an aside, I was going to Oz in April, but couldn't make it because of the pain. Have my hip replacement surgery on Tuesday. Fingers crossed!
