Arixtra

Mylan Inc.

Drug Names(s): fondaparinux sodium, Quixidar, GSK576428

Description: The antithrombotic activity of Arixtra is the result of antithrombin III (ATIII)-mediated selective inhibition of Factor Xa. By selectively binding to ATIII, Arixtra potentiates (about 300 times) the innate neutralization of Factor Xaby ATIII.
