Half of it leaves through the kidneys, so kidney function guides its use. Updated 2026-11-01 - Class: [Direct oral anticoagulants (DOACs)](https://durgical.com/en/pharmacology/classes/direct-oral-anticoagulants/) - Enzyme: Coagulation factor Xa - ATC code: B01AF03 ## ⚠ High-alert medication An error with this medicine can cause serious harm: double checks and protocols are used. ## Mechanism of action Edoxaban binds factor Xa directly, without antithrombin, and blocks both free and clot-associated factor Xa. Less factor Xa means less thrombin, so fibrin formation and thrombin-driven platelet aggregation are both suppressed. - Edoxaban binds the active site of factor Xa - Free and clot-associated Xa are blocked - Less thrombin forms, so less fibrin and less platelet activation ## Pharmacokinetics **Absorption** Oral bioavailability about 62%; food does not change it. Peak levels 1 to 2 hours after a dose. **Distribution** About 55% bound to plasma proteins, so it is not removed by dialysis in a useful way. **Metabolism** Minimal; only a small part goes through CYP3A4. It is a P-glycoprotein substrate. **Elimination** About half of the absorbed drug leaves unchanged in the urine. ## Indications - Prevention of stroke and systemic embolism in nonvalvular atrial fibrillation. [Atrial fibrillation →](https://durgical.com/en/conditions/atrial-fibrillation/) - Treatment of deep vein thrombosis, started after at least 5 days of heparin, low-molecular-weight heparin or fondaparinux. [Deep vein thrombosis →](https://durgical.com/en/conditions/deep-vein-thrombosis/) - Treatment of pulmonary embolism, with the same initial parenteral course. [Pulmonary embolism →](https://durgical.com/en/conditions/pulmonary-embolism/) ## Adverse effects ### Common - Bleeding: gums, nose, heavy menstrual bleeding, urine - More gastrointestinal bleeding than with warfarin ### Serious (rare, important) - Serious, sometimes fatal bleeding - Spinal or epidural haematoma with neuraxial anaesthesia or spinal puncture - Stroke if it is stopped early in atrial fibrillation ## Contraindications - Active pathological bleeding - End-stage kidney failure - Not recommended: mechanical heart valves, antiphospholipid syndrome; in the United States, also very high kidney function in atrial fibrillation ## Key interactions **Potent P-glycoprotein inhibitors (quinidine, dronedarone, erythromycin, ketoconazole, cyclosporine)** Raise edoxaban exposure; the regimen is reduced. **Rifampicin** Lowers edoxaban levels; combined use is avoided. **Antiplatelets, NSAIDs, other anticoagulants** Raise the risk of bleeding. ## What is monitored - Kidney function before starting and at least yearly - Signs of bleeding and haemoglobin when needed - Routine PT or INR is not useful; drug-calibrated anti-Xa assays exist ## Administration and safety - Oral, once a day, with or without food - For people who cannot swallow, tablets can be crushed and mixed with water or applesauce, or given through a gastric tube - In venous thrombosis it is started only after the initial parenteral anticoagulant course - For life-threatening bleeding, four-factor prothrombin complex concentrate may be considered; andexanet is approved for apixaban and rivaroxaban ## Nursing care - Check kidney function and body weight before the first dose - Watch for bleeding: black stools, blood in urine, heavy periods, vomiting blood - After spinal or epidural procedures, check for back pain, numbness or weakness - Teach the patient not to stop it on their own and to tell every dentist and surgeon ## Pregnancy and breastfeeding Data in pregnancy are limited; pregnancy is discussed with the treating team before and during use. ## Memory aid EDOXaban: "-xaban" blocks Xa, once a day, and the kidneys hold half of the key. ## Test yourself Think of the answer, then tap the question to see it. ## How is edoxaban started for deep vein thrombosis, compared with rivaroxaban and apixaban? Edoxaban starts only after at least 5 days of heparin, low-molecular-weight heparin or fondaparinux; rivaroxaban and apixaban can be started straight away. ## Which type of bleeding is more common with edoxaban than with warfarin? Gastrointestinal bleeding; intracranial bleeding, in contrast, is less common. ## Why can dialysis not remove edoxaban in a useful way? Like the other oral factor Xa inhibitors, it is too protein-bound for dialysis to clear it effectively.
