Danaparoid sodium (Orgaran) is an anticoagulant[1] with an antithrombotic action due to inhibition of thrombin generation (TGI) by two mechanisms: indirect inactivation of Factor Xa via AT and direct inhibition of thrombin activation of Factor IX (an important feedback loop for thrombin generation). It also possesses a minor anti-thrombin activity, mediated equally via AT and Heparin Co-factor II producing a ratio of anti-Xa:IIa activity >22. [Meuleman DG. Haemostasis 1992;22:58-65 and Ofosu FA Haemostasis 1992;22:66-72]
Danaparoid is a low molecular weight heparinoid devoid of heparin. It consists of a mixture of heparan sulfate, dermatan sulfate, and chondroitin sulfate.[2] It is chemically distinct from heparin, has different protein-binding properties because of its low degree of sulphation and low surface charge density and thus has little cross-reactivity in heparin-intolerant patients.
The TGI activity, considered by Fernandes et al. [Thromb Haemostas 1987;57/3:286-93] to provide an index of antithrombotic potential, of danaparoid has a half-life of 6.7 hours.
