WebDirect thrombin inhibitors bind thrombin with high affinity, preventing the interaction of thrombin with its substrates. Direct thrombin inhibitors inhibit platelet PAR receptors, without interfering with the platelet hemostatic role. Licensed DTIs include hirudin, bivalirudin, and argatroban; a number of novel products are in development. WebJan 20, 2024 · Direct thrombin inhibitors (bivalirudin) Direct thrombin inhibitors (DTIs) exert their anticoagulant effects by directly binding, without the need for a co-factor, to thrombin. Therefore, DTIs inhibit thrombin activity and thrombin-mediated activation of other coagulation factors (e.g. fibrin formation from fibrinogen) as well as thrombin ...
WebBivalirudin binds to both the active site and the substrate recognition site of thrombin in a noncompetitive manner. The former bond is slowly cleaved by thrombin itself, leaving a smaller molecule bound to the fibrinogen-binding site but with lower affinity than intact bivalirudin ( 28,29 ). WebUnlike heparin, direct thrombin inhibitors produce a predictable anticoagulant response that is unaffected by platelet factor 4, and they inhibit fibrin-bound thrombin. Three parenteral direct thrombin inhibitors—hirudin, bivalirudin and argatroban—are currently licensed for use in North America, and orally available direct thrombin ...
