Danaparoid

Danaparoid sodium (Orgaran®) is an anticoagulant that works by inhibiting activated factor X (factor Xa).

Danaparoid is considered a “low molecular weight heparin” by some sources, but is chemically distinct from heparin and thus has little cross-reactivity in heparin-intolerant patients.

It is used to prevent deep venous clots, particularly in situations with a high risk of clot formation, such as after hip surgery.

It is also used as a heparinoid substitute in heparin-induced thrombocytopenia which may otherwise cause paradoxical thrombosis.

On August 14, 2002, this drug was withdrawn by Organon International.^[1]
