Atnativ Uses

Atnativ is primarily injected to patients with deficient antithrombin III concentrate and especially for patient with recurrent thromboembolism and pulmonary embolism. Atnativ inhibits several activated coagulation factors of the intrinsic and common pathways including thrombin, Xa and IXa. The action of antithrombin III is activated by heparin, a compound released by basophils and mast cells.

Heparin increases the rate of the thrombin-antithrombin reaction at least 1000-fold by serving as a catalytic template to which both the inhibitor and the protease bind thus preventing the conversion of fibrinogen into fibrin. Antithrombin III deficiency is a rare hereditary disorder common in patients who suffers recurrent venous thrombosis and pulmonary embolism. Therefore, Atnativ is used by patients with conditions such as;

  • Venous thromboembolism
  • Pulmonary embolism
