Antithrombin Alfa is a recombinant antithrombin , an anticoagulant, that is used for the prevention of thromboembolic events in patients that have hereditary deficiency of antithrombin in high risk situations.
Hereditary antithrombin deficiency causes an increased risk of venous thromboembolism (VTE). In high risk situations, such as surgery or trauma or for pregnant women during the peri-partum period, the risk of development of VTEs is 10-50 times greater than the general population. In hereditary antithrombin deficient patients antithrombin alfa normalizes plasma antthrombin activity levels during peri-operative and peri-partum periods.
