DABIGATRAN ETEXILATE: NEW DIRECT THROMBIN INHIBITORS ANTICOAGULANTS
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2011, Vol 2, Issue 4
Abstract
Thrombin plays a key role in thrombotic events, and therefore thrombin inhibition represents a therapeutic target for numerous thromboembolic diseases. Thrombin is responsible for the conversion of soluble fibrinogen to fibrin; clot stabilization through activation of factor XIII and the formation of cross-linkage among fibrin molecules; and the generation of additional thrombin through activation of factors V, VIII, and XI. Direct thrombin inhibitors are an innovative class of anticoagulants that bind directly to thrombin to inhibit its actions and impede the clotting process. Dabigatran is the first direct thrombin inhibitor, orally available first approval by US Food and Drugs Administration in 2010. Specifically and reversibly inhibits thrombin, so the duration of action is predictable. The anticoagulant effect correlates well with plasma drug concentrations, which implies an effective anticoagulation with low bleeding risk without major problems of interactions with other drugs. The predictable pharmacokinetics and pharmacodynamics characteristics of dabigatran may facilitate dental management of patients who until now have been in treatment with traditional anticoagulants, given that it doesn’t require routine laboratory monitoring in the vast majority of patients treated. They also present a profile of drug interactions very favorable.
