Edoxaban is a commonly used anticoagulant medication that is used to prevent blood clots in patients with a high risk of developing thrombosis. Edoxaban stable isotopes are a type of isotopic labeling that is used in the development and testing of the drug. These stable isotopes are used to help researchers identify and quantify the drug in samples, which can help improve the accuracy and effectiveness of the treatment. Edoxaban stable isotopes are also used in the development of new drugs and in the study of the pharmacokinetics and pharmacodynamics of existing drugs.
