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

Contents

Danaparoid is a heparinoid but considered to be a low molecular weight heparin by some sources. However it is chemically distinct from heparin, has different protein binding properties and thus has little cross-reactivity in heparin-intolerant patients.

It consists of a mixture of heparan sulfate, dermatan sulfate, and chondroitin sulfate.

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 (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.

Discontinuation

On August 14, 2002, this drug was withdrawn by Organon International.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

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

Administration

IV and SC

Side effects

  • Bleeding (solely restricted to patients undergoing cardio-pulmonmary surgery with by pass)<Magnani HN, Gallus AG. Heparin-induced thrombocytopenia (HIT) A report of 1478 clinical outcomes of patients treated with danaparoid (Orgaran) from 1982 to mid 2004." Thromb Haemost 2006; 95: 967-871>
  • Low platelets, due to a low level of structural similarity between danaparoid and heparin, i.e.only in some patients sensitive to heparin or a LMWH but to date never developed spontaneously.
  • Possibly Asthma exacerbations, due to allergies to sulfites contained within the medicine (no case has been reported to date).
