U.S. seeks more data on blood thinner Plavix
2009-01-28
U.S. health regulators are reviewing the effectiveness in some patients of the widely used blood thinner Plavix, made by Sanofi-Aventis SA and Bristol-Myers Squibb Co.
The move comes after several studies found the blockbuster drug did not work as well in certain people possibly because patients metabolized it differently depending on their genetic makeup or their other medications, the U.S. Food and Drug Administration said on Monday.
