Danaparoid sodium (Orgaran) is an anticoagulant[1] 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 consists of a mixture of heparan sulfate, dermatan sulfate and chondroitin sulfate.[2]

It has also been described as a heparinoid.[3]

Uses

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[4][5] (HIT) which may otherwise cause paradoxical thrombosis. Danaparoid is used for thrombosis prophylaxis and treatment in heparin-induced thrombocytopenia patients, although cross-reactivity with heparin-induced antibodies can occur in 10–20% of the patients (ESRA). It has been proposed for use in Kasabach-Merritt syndrome.[6]

Discontinuation

On August 14, 2002, this drug was withdrawn by Organon International.[7] Due to a shortage in drug substance, the manufacturer discontinued providing the medication in the United States. It is available in several other countries.[8]

On the Schering-Plough website, Orgaran is described as "Marketed outside the U.S."[9]

Administration

IV and SC

Side effects

  • Bleeding problems
  • Low platelets, due to a low level of structural similarity between danaparoid and heparin
  • Asthma exacerbations, due to allergies to sulfites contained within the medicine
