Major bleeding occurs in about 4% of patients while on treatment with direct oral anticoagulants (DOACs). The case-fatality rate associated with these events is estimated to be about 5%. The specific roles of antidotes, when used with DOACs in reducing the case fatality or improving the overall clinical course of these events, are not thoroughly understood. To this regard, the US Food and Drug Administration as well as European Medicines Agency have recently licensed idarucizumab for the management of patients with life-threatening bleeding or the need for urgent surgery/procedures while on treatment with dabigatran...

The number of atrial fibrillation (AF) patients requiring thrombo-prophylaxis with oral anticoagulation is greatly increasing. The introduction of non-vitamin K oral anticoagulants (NOACs) in addition to standard therapy with dose-adjusted warfarin has increased the therapeutic options for AF patients. Despite a generally better safety profile of the NOACs, the risk of major bleedings still persists, and the management of serious bleeding is a clinical challenge. Areas covered: In the current review, risk of major bleeding in patients taking NOACs and general approaches to manage bleeding depending on severity, with a particular focus on specific reversal agents, are discussed...

BACKGROUND AND PURPOSE: Current guidelines do not recommend the use of intravenous recombinant tissue plasminogen activator in patients with acute ischemic stroke who receive direct oral anticoagulants. While the humanized monoclonal antibody idarucizumab can quickly reverse the anticoagulant effects of the thrombin inhibitor dabigatran, safety data for subsequent tissue plasminogen activator treatment are sparse. Here, we review current knowledge about dabigatran reversal prior to systemic reperfusion treatment in acute ischemic stroke...

Vitamin K antagonists are an effective group of oral anticoagulants. However because of genetic variability in their metabolism and multiple food and drug interactions, these drugs have narrow therapeutic window with unpredictable anticoagulant effects requiring constant monitoring. Several newer direct acting oral anticoagulants have been approved for prevention of stroke in patients with nonvalvular atrial fibrillation and treatment or prevention of venous thromboembolism. The direct acting oral anticoagulants include the direct thrombin inhibitor (dabigatran) and the factor Xa inhibitors (rivaroxaban, apixaban, and edoxaban)...

Direct oral anticoagulants (DOAC) are indicated for stroke prevention in atrial fibrillation and for the prevention and treatment of venous thromboembolism. As any anticoagulant, they are associated with a bleeding risk. Management of DOAC-induced bleeding is challenging. Idarucizumab, antidote for dabigatran, is currently available and is part of the therapeutic strategy, whereas antidotes for anti-Xa agents are under development. Activated or non-activated prothrombin concentrates are proposed, although their efficacy to reverse DOAC is uncertain...

BACKGROUND: Vitamin K inhibitors (e.g. warfarin) and indirect thrombin inhibitors (e.g. heparin) are widely used to prevent thromboembolic disorders (e.g. myocardial infarction, venous thromboembolism, and stroke). These agents have been mainstays of anticoagulation for people older than 60 years. However, their administration is associated with a risk of bleeding and requires careful monitoring of patients. Novel oral anticoagulants (NOACs), such as dabigatran, are significantly safer in preventing thromboembolism than warfarin and heparin (sporadically causes thrombocytopenia) and are more specific for their target protein, thrombin...

Dabigatran, a direct thrombin inhibitor and one of the new class of direct oral anticoagulants, is increasingly used in preference to warfarin because of its efficacy and ease of administration. However, because the drug is cleared by the kidneys, it can accumulate in plasma and increase the risk for bleeding in patients with decreased kidney function. We report a patient with end-stage liver disease who developed life-threatening hemorrhage and acute kidney injury while taking dabigatran, 150mg, twice daily...

Since direct oral anticoagulants (DOAC) have become available, use of anticoagulant treatment has become easier and safer-for patients suffering from thromboembolic diseases as well as for patients with atrial fibrillation: Because of constant bioavailability, fixed dose regimen treatment is possible, monitoring not necessary and severe bleeding complications-particularly intracranial hemorrhages-rare in comparison to vitamin K anticoagulants. To gain all these advantages, it is essential to give DOAC in the correct dosage...

: Atrial fibrillation is the most common arrhythmia in over-midlife patients. In addition to systolic heart failure, cerebral thromboembolism represents the most dramatic complication of this rhythm disorder, contributing to morbidity and mortality. Traditionally, anticoagulation has been considered the main strategy in preventing stroke and systemic embolism in atrial fibrillation patients and vitamin K-dependent antagonists have been widely used in clinical practice. Recently, the development of direct oral anticoagulants has certainly improved the management of this disease, providing, for the first time, the opportunity to go beyond vitamin K-dependent antagonists limits...

The superiority of dabigatran has been well proven in the standard dosing regimen in prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF) and extended venous thromboembolism (VTE) treatment. Dabigatran, an anticoagulant with a good safety profile, reduces intracranial bleeding in patients with atrial fibrillation and decreases major and clinically relevant non-major bleeding in acute VTE treatment. However, several important clinical issues are not fully covered by currently available directions with regard to dabigatran administration...

The introduction of nonvitamin K antagonistic, direct oral anticoagulants (DOAC) made thromboembolic prophylaxis easier for patients. For many physicians, however, there is still uncertainty about monitoring, preoperative discontinuation, and restarting of DOAC therapy. Guidelines for the management of bleeding are provided, but require specific therapeutic skills in the management of diagnostics and therapy of acute hemorrhage. Small clinical studies and case reports indicate that unspecific therapy with prothrombin complex concentrates (PCC) and activated PCC (aPCC) concentrate may reverse DOAC-induced anticoagulation...

Dabigatran etexilate (DE) is a direct thrombin inhibitor, which has been approved for the treatment of non-valvular atrial fibrillation (AF), and for the prevention and treatment of venous thromboembolism (VTE). Despite large randomized clinical trials and independent observational studies providing robust data concerning DE safety and efficacy, some physicians still perceive mild-to-moderate renal impairment and old age as a relative contraindication to its use. In this article, we review the available scientific evidence supporting the use of DE in these clinical situations...

PURPOSE: Patients are increasingly treated with direct oral anticoagulants (DOACs) for the prevention of stroke due to non-valvular atrial fibrillation and for the treatment of venous thromboembolism. When these patients present for urgent or emergent surgical procedures, they present a challenge to the anesthesiologist who must manage perioperative risk due to anticoagulation. The purpose of this module is to review the literature surrounding the perioperative management of DOACs. Timing, laboratory monitoring, and availability of reversal agents are important considerations to optimize patients being treated with DOACs who require emergent surgery...

Essentials Reversal of anticoagulant effects of dabigatran may occur despite application of idarucizumab. Monitoring of dabigatran level after antidote application is crucial to detect rebound. Repeated doses of idarucizumab may be necessary in cases of massive dabigatran accumulation. Combination of antidote application and renal replacement therapy may offer additional benefit. SUMMARY: Idarucizumab is a monoclonal antibody fragment designed for reversing the anticoagulant effects of dabigatran...

The worldwide increase in the aging population and the associated increase in the prevalence of atrial fibrillation and venous thromboembolism as well as the widespread use of direct oral anticoagulants (DOAC) have resulted in an increase of the need for the management of bleeding complications and emergency operations in frail, elderly patients, in clinical practice. When severe bleeding occurs, general assessment should include evaluation of the bleeding site, onset and severity of bleeding, renal function, and concurrent medications with focus on antiplatelet drugs and nonsteroidal anti-inflammatory drugs (NSAID)...

Patients treated with anticoagulants have an unavoidable risk of bleeding complications. There are, for all oral anticoagulants, several potential options for management of major bleeding. The first action is to assess the causative role of the anticoagulant in the current bleeding. Supportive measures have been assessed in several post hoc analyses of the phase III pivotal trials with the non-vitamin K antagonist oral anticoagulants (NOACs). Those results will be reviewed here together with emerging data on the efficacy and safety of the specific antidotes idarucizumab (for dabigatran) and andexanet-α (for factor Xa inhibitors)...

Dabigatran is a direct oral anticoagulant drug exhibiting clinical benefits over vitamin K antagonists. A procedure for reversing the anticoagulant effect of direct oral anticoagulants may be needed in emergency clinical settings, and is traditionally accomplished by using plasma products or hemostatic physical interventions. Idarucizumab, a specific antidote for dabigatran, has recently become available. This compound can be rapidly administered by intravenous injection and is effective in reversing anticoagulation in few minutes...

At present, the direct thrombin inhibitor dabigatran is the only one amongst the new direct anticoagulants which has an effective, specific reversal agent. The novel agent idarucizumab is a humanized, monoclonal antibody fragment binds to dabigatran within minutes thereby offers an opportunity to induce a safe, long-lasting reverse of the anticoagulant effects of dabigatran. The authors describe the first use of idarucizumab in Hungary (23. 05. 2016) in an old female patient with non-valvular paroxysmal atrial fibrillation of high stroke risk-score and renal dysfunction who was taking dabigatran (2 x 110 mg/day) when an acute abdomen developed requiring emergency cholecystectomy...
