ABSTRACT
Danaparoid (Orgaran®) has recently been marketed in Canada and is approved for the prevention of venous thrombosis following orthopedic, major abdominal and thoracic surgery; and following nonhemorrhagic stroke. Danaparoid is composed of heparin, dermatan, and chondroitin sulphates and exerts its anticoagulant effect by enhancing the activities of anti-thrombin III and heparin cofactor II. It is at least as effective as other thromboprophylaxis agents in the prevention of post-operative thrombosis. It has a low cross-reactivity rate with the antibody responsible for heparin-induced thrombocytopenia (HIT) and, thus, can be used with caution in patients who have developed HIT.
RÉSUMÉ
Le danaparïde (Orgaran®) a été lancé récemment sur le marché canadien et approuvé dans la prévention de la thrombose veineuse consécutive à une chirurgie orthopédique, abdominale importante ou thoracique, et à un ACV non hémorragique. Le danaparïde est un composé d'héparane, de dermatane et de sulfates de chondroïtine. Il exerce une action anticoagulante en accroissant l’activité de l'antithrombine III et du cofacteur II de d’héparine. Il est du moins aussi efficace que d'autres agents thromboprophylactiques pour prévenir les thromboses post-opératoires. Son taux de réactivité croisée avec l'anticorps responsable de la thrombocytopénie musée par l'héparine est faible et peut donc être utilisé avec circonspection chez les patients chez qui s'est développé cette condition.
