Question: is arixtra a heparin product?
Answer: Fondaparinux (Arixtra) is an anticoagulant that shares the same pentasaccharide sequence as UFH and LMWH for the binding to antithrombin, however it has no extra chain and thus, is not considered a heparin product. It is also known to not cause HIT, as seen with UFH and LMWH.
