Summary
Edoxaban, a novel oral direct factor Xa inhibitor, shows promise in preventing stroke and venous thromboembolism. Ongoing trials evaluate its efficacy in atrial fibrillation and deep vein thrombosis patients.
Area of Science:
- Pharmacology
- Cardiovascular Medicine
- Thrombosis Research
Background:
- Edoxaban is an orally available direct factor Xa inhibitor, developed from DX-9065a.
- It is the third new oral anticoagulant in its class approved for preventing venous thromboembolism post-orthopaedic surgery.
Purpose of the Study:
- To discuss the pharmacological properties of edoxaban.
- To review its late-stage clinical development for stroke prevention in non-valvular atrial fibrillation and venous thromboembolism treatment/prevention.
Main Methods:
- Phase III clinical trials: ENGAGE AF-TIMI 48 (stroke prevention in atrial fibrillation) and HOKUSAI VTE (venous thromboembolism).
- These trials involve large patient cohorts (21,107 in ENGAGE AF-TIMI 48, planned 7,500 in HOKUSAI VTE).
Main Results:
- Edoxaban exhibits a time to peak plasma concentrations of 1-2 hours and a half-life of approximately 10 hours.
- Clinical approval for venous thromboembolism prevention after major orthopaedic surgery has been obtained.
Conclusions:
- Edoxaban is a significant development in oral anticoagulation therapy.
- Further data from large-scale trials will clarify its role in managing stroke and venous thromboembolism.

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...
