The main purpose of anticoagulants is to diminish fibrin formation, thereby decreasing the risk of venous or arterial thrombosis. Vitamin K antagonist have been used for many decades in order to achieve reduced thrombotic risk, despite major drawbacks of this class of drugs such as cumbersome dossing and monitoring of anticoagulant status. To overcome these drawbacks of VKA, new classes of anti...

Atrial fibrillation (AF) is a major risk factor for stroke. Currently, acetylsalicylic acid (a platelet inhibitor) and vitamin K antagonists (VKAs; oral anticoagulants), including warfarin, are the only approved antithrombotic therapies for stroke prevention in patients with AF. Although effective, VKAs have unpredictable pharmacological effects, requiring regular coagulation monitoring and dos...

Background Four novel direct oral anticoagulants (DOACs) named dabigatran, rivaroxaban, edoxaban and apixaban have been recently introduced to overcome some of the drawbacks of existing anticoagulants. They have less interactions and do not require routine monitoring. However, there is not enough scientific data about the protocol to apply in these patients on DOACs undergoing dental treatment....

Introduction Recently, novel oral anticoagulants (rivaroxaban, dabigatran, apixaban) have been approved for pulmonary embolism (PE) treatment. Each anticoagulant used during initial and maintenance therapy has direct and indirect costs for healthcare systems. Demonstrating the costs of treatment with different anticoagulants in a specific patient group will be helpful for clinicians determining...

A new generation of antithrombotic agents has recently emerged. These provide direct inhibition of either thrombin (factor IIa [FIIa]) or FXa, and are increasingly replacing the classical anticoagulants (heparin and coumarins such as warfarin) in clinical practice for a variety of conditions. These agents have been designated several acronyms, including NOACs, DOACs, and TSOACs, respectively, r...

The recent introduction of direct oral anticoagulants, including rivaroxaban, dabigatran, apixaban, and edoxaban, for the acute treatment and secondary prevention of venous thromboembolism and in atrial fibrillation has been shown to provide greater clinical benefit than oral vitamin K antagonists. However, direct oral anticoagulants are associated with adverse events, the most common being maj...

Anticoagulants are amongst the most commonly prescribed medications worldwide. Although rare, localised and systemic drug reactions have been reported with anticoagulants that can lead to significant morbidity and mortality. Some of the first signs of drug reactions to anticoagulants are cutaneous changes that, when recognised early, can prevent significant complications. Dermatologists should ...
