Effects of the direct thrombin inhibitor dabigatran and its orally active prodrug, dabigatran etexilate, on thrombus formation and bleeding time in rats.

Dabigatran is a reversible direct, selective thrombin inhibitor, undergoing clinical development as its orally active prodrug, dabigatran etexilate. The objective of this trial was to assess the antithrombotic and anticoagulant effects of dabigatran and dabigatran etexilate in a rat model of venous thrombosis. In order to do this a modified Wessler model was used to assess the antithrombotic and anticoagulant effects of intravenous (i.

In-vitro profile and ex-vivo anticoagulant activity of the direct thrombin inhibitor dabigatran and its orally active prodrug, dabigatran etexilate.

Dabigatran is a reversible and selective, direct thrombin inhibitor (DTI) undergoing advanced clinical development as its orally active prodrug, dabigatran etexilate. This study set out to determine the molecular potency and anticoagulant efficacy of dabigatran and its prodrug dabigatran etexilate. This was achieved through enzyme inhibition and selectivity analyses, surface plasmon resonance studies, platelet aggregation, thrombin generation and clotting assays in vitro and ex vivo.
