Edoxaban: A direct oral anticoagulant.
Review published in American journal of health-system pharmacy : AJHP : official journal of the American Society of Health-System Pharmacists (2017)
Abstract
PURPOSE: The pharmacology, pharmacokinetics, pharmacodynamics, clinical efficacy, safety, and place in therapy of edoxaban for prevention of stroke in patients with nonvalvular atrial fibrillation (AF) and treatment of venous thromboembolism (VTE) are reviewed. SUMMARY: Although warfarin has been an established therapy for stroke prevention in AF and VTE, the need for agents with less monitoring requirements, fewer food and drug interactions, and a lower risk of major bleeding led to the development of direct oral anticoagulants (DOACs). Current DOACs work by either directly blocking thrombin (dabigatran) or inhibiting factor Xa (apixaban, edoxaban, and rivaroxaban). Edoxaban is the newest DOAC and only the second Food and Drug Administration-approved anticoagulant for once-daily administration. Unlike apixaban and rivaroxaban, edoxaban does not interact with the cytochrome P-450 system. The results of the ENGAGE AF-TIMI 48 and Hokusai-VTE trials demonstrated edoxaban's noninferiority to warfarin. However, the adverse-effect profile of edoxaban may limit the drug's use in clinical practice; in clinical trials, patients with AF who had a creatinine clearance of ≥95 mL/min had a higher rate of strokes with the use of edoxaban versus warfarin. CONCLUSION: A review of the literature showed that edoxaban, the most recently approved DOAC, is noninferior to warfarin for management of VTE (after parenteral anticoagulant therapy) and for stroke risk reduction in many patients with nonvalvular AF.

Why This Matters for Hirudotherapy
This review summarizes the pharmacology, pharmacokinetics, and clinical efficacy of edoxaban, a direct oral anticoagulant that functions as a factor Xa inhibitor, for the prevention of stroke in atrial fibrillation and treatment of venous thromboembolism. It details the drug's non-inferiority to warfarin alongside specific safety warnings regarding renal clearance. This article is of indirect interest to ASH because factor Xa inhibition is a prominent mechanism found in various leech secretions, such as those containing antistasin. Comparing synthetic factor Xa inhibitors to natural leech-derived counterparts contextualizes the pharmacological potency of leech saliva. However, the study has no direct relevance to hirudotherapy; it focuses strictly on a synthetic oral drug, with no mention of leeches, leech extracts, or comparative biological data.
