Antithrombin III is a naturally occurring inhibitor of several coagulation enzymes, primarily thrombin and factor Xa. It is used therapeutically as a replacement therapy in patients with hereditary or acquired antithrombin deficiency, often to prevent thromboembolic events during high-risk procedures. Antithrombin III (human plasma-derived or recombinant) is approved and used clinically.
Pharmacokinetics
Pharmacokinetics in healthy adults and patients with hereditary antithrombin deficiency; administered as intravenous bolus or infusion.
