The companies say this new generation of blood thinners works better than the long-time standard, warfarin. Millions of patients and their doctors have long wanted a better alternative to warfarin, an inexpensive generic drug also sold under brand names such as Coumadin. Getting the dose of warfarin correct is so tricky that patients need frequent blood tests to ensure they're getting enough to prevent clots but not enough to cause internal bleeding. Some foods interact with warfarin, adding to the difficulty. The newer drugs also carry risks of serious internal bleeding. They cost nearly twice the price for warfarin, including the cost of the blood tests that drug requires.
