Direct thrombin inhibitors (DTIs) are a class of medication that act as anticoagulants (delaying blood clotting) by directly inhibiting the enzyme thrombin (factor IIa). Some are in clinical use, while others are undergoing clinical development. Several members of the class are expected to replace heparin (and derivatives) and warfarin in ...
Direct thrombin inhibitors (DTIs) are a class of anticoagulant drugs that can be used to prevent and treat embolisms and blood clots caused by various diseases. They inhibit thrombin, a serine protease which affects the coagulation cascade in many ways. DTIs have undergone rapid development since the 90's.
Heparin is the most widely used intravenous clinical anticoagulant worldwide. [82] ... An oral direct thrombin inhibitor, ximelagatran (Exanta), ...
Heparin binds to the enzyme inhibitor antithrombin III (AT), causing a conformational change that results in its activation through an increase in the flexibility of its reactive site loop. [52] The activated AT then inactivates thrombin , factor Xa and other proteases.
Direct factor Xa inhibitors include rivaroxaban, apixaban and edoxaban, and are types of direct oral anticoagulant (DOAC), which are blood thinning drugs, one of the classes of antithrombotic drugs. [4][5][6] They are commonly prescribed to treat and prevent blood clots in veins, prevent stroke and embolism in people with non-valvular atrial ...
Molecular structure of argatroban, a direct thrombin inhibitor used as an alternative to heparin in HIT. Given the fact that HIT predisposes strongly to new episodes of thrombosis, simply discontinuing the heparin administration is insufficient.
Low-molecular-weight heparin (LMWH) is a class of anticoagulant medications. [1] They are used in the prevention of blood clots and, in the treatment of venous thromboembolism (deep vein thrombosis and pulmonary embolism), and the treatment of myocardial infarction. Heparin is a naturally occurring polysaccharide that inhibits coagulation ...
Animal studies suggested direct Xa-inhibition to be a more efficient approach to anticoagulation compared to direct thrombin inhibitors, especially offering a wider therapeutic window and reducing the risk of rebound thrombosis, (increase in thromboembolic events occurring shortly after the withdrawal of an antithrombotic medication) compared ...
