There are two types of heparins: high molecular weight heparins High molecular weight heparins require blood monitoring to check the activated partial thromboplastin time aPTT to measure the intrinsic pathway low molecular weight heparins.

The History of Anticoagulants

Based on preclinical and clinical trial data published to date, direct Factor Xa inhibitors, such as Xarelto , have the potential to advance the field of anticoagulant therapy. Xarelto , protects against blood clots by selectively targeting Factor Xa, the pivotal point in the coagulation process.

They are used to prevent abnormal blood clots from forming and existing clots from getting bigger. This allows the body to dissolve the clots

components of the coagulation pathway to form clots. Factor Xa inhibitors are generally used as prophylaxis in patients having hip and knee replacement surgery, where blood clots can form and lead to deep vein thrombosis and pulmonary embolism.

If this patient s blood thinner is warfarin, how should the anticoagulant effects be reversed? Warfarin is a vitamin K antagonist that depletes levels of factors II, VII, IX, X, and protein C and S, resulting in less downstream thrombin, fibrin, and cross-linked fibrin clots. Its anticoagulant activity is represented in the INR.

antithrombotics are also used.[15,16] On the anticoagulants front, clinically available anticoagu-lants include the indirect anticoagulants of warfarin and heparins as well as the direct anticoagulants of thrombin inhibitors (argatroban, dabigatran, and bivalirudin) and factor Xa inhibitors (rivaroxaban, apixaban, edoxaban, and betrixaban).

Anticoagulants are used to treat blood clots and reduce the risk of them forming in the arteries and veins, which can lead to pulmonary embolism, stroke or other organ damage. Apixaban and rivaroxaban belong to a newer class of anticoagulants called factor Xa (FXa) inhibitors, which work by
