Current Real-World Status of Oral Anticoagulant Management in Japanese Patients

Anticoagulant therapy is a drug therapy that inhibits the formation of blood clots. Although anticoagulants are effective in preventing thromboembolism, they also carry the risk of bleeding, so they must be managed carefully, taking both efficacy and safety into account. Evidence regarding the effectiveness and safety of each anticoagulant has already accumulated through many large clinical trials and post-marketing surveillance. However, when making decisions in clinical practice, it is necessary to always take into consideration differences in patient populations between clinical trials and actual clinical practice, as well as differences in historical background. (For example, there are differences in antiplatelet drugs and coronary artery interventions that were mainly used in each era.) In this review we discuss the effectiveness and safety of currently used anticoagulants, focusing on different patient backgrounds and points to keep in mind regarding their proper use, based on the latest reports in Asian populations, especially Japanese people, over the past 1-2 years.
