Anticoagulants are drugs that treat blood clots, and help prevent blood clot formation in the veins and arteries. The following are 10 points to remember from this review about direct oral anticoagulants (DOACs): Since 2009, four DOACs have been introduced for treatment of venous thromboembolism and stroke prevention in nonvalvular atrial fibrillation (AF). For example, patients with moderate renal function can be treated with one of the factor Xa inhibitors (apixaban, edoxaban, or rivaroxaban). Currently licenced direct oral anticoagulants selectively target thrombin (eg, dabigatran) or coagulation factor Xa (eg, apixaban, betrixaban, edoxaban, and rivaroxaban). Background and Purpose- There are scarce data regarding the safety of intravenous thrombolysis (IVT) in acute ischemic stroke among patients on direct oral anticoagulants (DOACs). MEDLINE and PubMed searches were carried out by using the following phrases: new oral anticoagulants, novel oral anticoagulants, direct acting oral anticoagulants, direct inhibitors of coagulation, non–vitamin K antagonist oral anticoagulants, warfarin, Coumadin, dabigatran, apixaban, edoxaban, rivaroxaban, fertility, pregnancy, childbearing age, maternal complications, fetal … 1 The NOACs currently available in Canada (i.e., dabigatran, rivaroxaban, apixaban) are designed to target thrombin (direct thrombin inhibitors) or activated factor X (FXa).

Certain clinical situations may also favor one DOAC over another. We list the most important contraindications. In: Post TW, ed. Direct Oral Anticoagulants: Unique Properties and Practical Approaches to Management. The introduction of direct oral anticoagulants (OACs) for the treatment and prevention of thromboembolic disease represents a shift from the traditional vitamin K antagonist-based therapies, which have been the mainstay of treatment for almost 60 years. Selective thrombin inhibitor Selective direct Xa inhibitor Selective direct Xa inhibitor Selective direct Xa inhibitor . DOACs are both rapid and short-acting agents with relatively low bleeding risks and good overall safety profiles. Drug interactions with warfarin: what clinicians need to know. Factor Xa inhibitors have predictable anticoagulant effects and do not require routine monitoring, unlike some other anticoagulants. Apixaban (Eliquis ) and rivaroxaban (Xarelto ) are direct, highly selective, orally active inhibitors of activated factor X (factor Xa). This includes bruising, bleeding gums, nosebleeds, prolonged bleeding from cuts, blood in the urine or stools, haemoptysis, subconjunctival haemorrhage, and vaginal bleeding in a postmenopausal woman.

Antithrombotic therapy for prosthetic heart valves: Indications. Patients looking for single-drug treatment of VTE (especially outpatient treatment) will favor the use of apixaban or rivaroxaban, which do not require 5–10 days of pre-treatment with low molecular weight heparin as is required for dabigatran and edoxaban. Direct-acting oral anticoagulants (DOACs), such as rivaroxaban, may interact with other medicines, including antibacterials and antivirals. Phase-3 studies and real-world evaluations have established that the safety profile of DOACs is superior to those of VKAs. Ginsberg JS, Crowther MA.
