A target international normalized ratio (INR) of 2-3 has been recommended for patients with atrial fibrillation (AF) and risk factors for thromboembolism. This recommendation is largely based on evidence from observational studies a decade ago. This study utilized collective data from modern trials with warfarin controls to examine the relationship of warfarin anticoagulation, as assessed by INR, on the clinical outcome events of interest. METHODS: Data on warfarin-treated patients from 3 clinical studies supporting the approval of dabigatran (Pradaxa® ), apixaban (Eliquis® ), and edoxaban (Savaysa® ) were pooled...

Monitoring the effect of dabigatran (Pradaxa® ) is challenging. The aim of this study was to evaluate if thrombelastography reaction time (TEG® R) could detect the anticoagulant effect of dabigatran showing a correlation between TEG® R, Hemoclot Thrombin Inhibitor (HTI) assay and Ecarin Clotting Time (ECT) in patients with non-valvular atrial fibrillation (NVAF). Blood samples from 35 AF patients receiving either 110 mg (n 19) or 150 mg (n 16) dabigatran twice daily were analyzed with TEG® , HTI and ECT 2-3 h after dabigatran intake...

BACKGROUND AND OBJECTIVE: Previous literature assessing ocular hemorrhagic complications of anticoagulant/antiplatelet medications in routine clinical practice is limited. This study evaluates the prevalence of spontaneous ocular hemorrhagic events associated with anticoagulation/antiplatelet therapy. PATIENTS AND METHODS: A retrospective study was performed to identify patients taking anticoagulants (rivaroxaban [Xarelto; Janssen Pharmaceuticals, Beerse, Belgium], bivalirudin [Angiomax; The Medicines Company, Parsippany, NJ], lepirudin [Refludan; Bayer HealthCare Pharmaceuticals, Berlin, Germany], dabigatran [Pradaxa; Boehringer Ingelheim, Ingelheim am Rhein, Germany], and argatroban) and antiplatelet agents (clopidogrel [Plavix; Bristol-Myers Squibb, New York City, NY], prasugrel [Effient; Lilly Medical, Indianapolis, IN], and ticagrelor [Brilinta; AstraZeneca, Cambridge, UK]) who presented for an eye examination...

Pradaxa is a novel oral anticoagulant, which was originally used to prevent thrombosis following joint replacement surgery. The aim of the current study was to investigate the effect dabigatran on acute myocardial infarction through regulating no‑reflow phenomenon and oxidative stress, neutrophil intraplaque infiltration and apoptosis. In the present study, dabigatran significantly inhibited the infarct size, increased arterial pressure and reduced no‑reflow phenomenon in acute myocardial infarction (AMI) vehicle rabbits...

COMPARATIVE STUDY
Adriane Mayer, Philipp Schuster, Bernd Fink
INTRODUCTION: Patients who have undergone hip or knee replacement surgery are exposed to a high risk of developing a post-operative venous thromboembolus and so have a need for an effective, medication-based, thrombosis prophylaxis. New orally active anticoagulants have been available for a few years now. These specific substances directly block either thrombin (e.g., dabigatran etexilate) or Factor Xa (e.g., apixaban). It is not clear whether there are any efficacy differences between these two substances because there have never been any head-to-head studies carried out...

Dabigatran etexilate (Pradaxa®) is approved in the EU for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation (NVAF) and one or more risk factors. Dabigatran etexilate is a prodrug of dabigatran, a direct inhibitor of thrombin. In patients with NVAF in the phase III RE-LY trial, dabigatran etexilate dosages of 110 and 150 mg twice daily were noninferior to warfarin with regard to the risk of stroke or systemic embolism (primary efficacy endpoint). The higher dosage was associated with a significantly lower risk of stroke or systemic embolism than warfarin, with no significant between-group difference in the risk of major bleeding (primary safety endpoint)...

Direct oral anticoagulants (DOACs) are in wide use among patients requiring both short- and long-term anticoagulation, mainly due to their ease of use and the lack of monitoring requirements. With growing use of DOACs, it is imperative that physicians be able to manage patients on these medications, especially in the perioperative period. We aim to provide guidance on the management of DOACs in the perioperative period. In this review, we performed an extensive literature search summarizing the management of patients on direct-acting anticoagulants in the perioperative period...

There is considerable interest in dabigatran etexilate (Pradaxa) and its major metabolite, dabigatran, which has been shown to be an important inhibitor of thrombin and clotting. In this study, the fluorescent excitation and emission spectra of dabigatran and dabigatran etexilate were characterized. In addition, a ultra performance liquid chromatography (UPLC) and high performance liquid chromatography (HPLC) method using fluorescent detection was developed for the analysis of dabigatran. Dabigatran and dabigatran etexilate were found to have excitation and emission maxima of 310 and 375 nm and 335 and 400 nm, respectively...

Idarucizumab (Praxbind(®)), a humanized monoclonal antibody, is a specific reversal agent for the direct oral thrombin inhibitor dabigatran, available as its prodrug dabigatran etexilate (Pradaxa(®)). Idarucizumab is approved in several countries (including the USA, the EU, Canada and Australia) for use in adult patients on dabigatran when the reversal of its anticoagulant effects is required for emergency surgery/procedures or in the event of life-threatening or uncontrolled bleeding. In the ongoing pivotal RE-VERSE AD trial in these populations (n = 90), intravenous idarucizumab 5 g reversed dabigatran-induced prolongation of dilute thrombin time (dTT) and ecarin clotting time (ECT) within minutes...

Dabigatran etexilate or pradaxa, a novel oral anticoagulant, is a reversible, competitive, direct thrombin inhibitor. It is used to prevent strokes in patients with atrial fibrillation and the formation of blood clots in the veins (deep venous thrombosis) in adults who have had an operation to replace a hip or a knee. Pradaxa is the only novel oral anticoagulant available with both proven superiority to warfarin and a specific reversal agent for use in rare emergency situations. The detailed description of the synthesis of carbon-13 and carbon-14 labeled dabigatran etexilate, and tritium labeled dabigatran is described...

REVIEW
C F Munson, A J Reid
Novel oral anticoagulants (NOACs) have emerged as a good alternative to warfarin in the prevention of stroke for patients with atrial fibrillation. NOAC use is increasing rapidly; therefore, greater understanding of their use in the perioperative period is important for optimal care. Studies and reviews that reported on the use of NOACs were identified, with particular focus on the perioperative period. PubMed was searched for relevant articles published between January 2000 and August 2015. The inevitable rise in the use of NOACs such as rivaroxaban (Xarelto™), apixaban (Eliquis™), edoxaban (Lixiana™) and dabigatran (Pradaxa™) may present a simplified approach to perioperative anticoagulant management due to fewer drug interactions, rapidity of onset of action and relatively short half-lives...

The objective of this study was to find a new parameter to monitor bleeding tendency after dabigatran etexilate (Pradaxa) medication in Chinese nonvalvular atrial fibrillation patients. Blood samples of 231 nonvalvular atrial fibrillation patients were collected and five routine coagulation examinations (prothrombin time/International normalized ratio, activated partial thromboplastin time, fibrinogen assay, thrombin time and D-dimer) were assayed. After dabigatran etexilate administration, prolonged activated partial thromboplastin time and thrombin time were observed, especially TT...

A 79-year-old woman was referred for rapid onset of painless bilateral vision loss. Anterior segment exams revealed bilateral spontaneous hyphema and fibrin accumulation. Observation of the posterior chamber by B-scan ultrasound showed vitreous hemorrhage and choroidal detachment bilaterally. No evidence of additional intraocular inflammation was present. Laboratory work-up for hematologic abnormalities was unremarkable. These hemorrhagic events were suspected to be a complication from taking the novel anticoagulant, dabigatran etexilate (Pradaxa; Boehringer, Ingelheim, Germany)...
