Factor Xa inhibitors are a class of anticoagulant medications that work by selectively targeting and inhibiting the activity of factor Xa, a key enzyme in the coagulation cascade. By inhibiting factor Xa, these medications prevent the formation of blood clots and reduce the risk of complications associated with conditions such as deep vein thrombosis, pulmonary embolism, and stroke. Factor Xa inhibitors are commonly used in the prevention and treatment of thromboembolic disorders and have been shown to be effective and well-tolerated in clinical trials. Some examples of factor Xa inhibitors include rivaroxaban, apixaban, and edoxaban.
