What medicine is used to prevent blood clot formation?

Anticoagulants, commonly known as blood thinners, are medications used to prevent blood clot formation. Examples include warfarin, rivaroxaban, apixaban, and dabigatran. These medications work by inhibiting specific factors in the blood coagulation process, thereby reducing the risk of clots in conditions such as atrial fibrillation or after certain surgeries. It's important for patients on anticoagulants to be monitored regularly to manage the risk of bleeding complications.
