Apixaban is a highly selective, orally bioavailable, and reversible direct inhibitor of free and clot-bound factor Xa. Factor Xa catalyzes the conversion of prothrombin to thrombin, the final enzyme in the coagulation cascade that is responsible for fibrin clot formation. [ 25 ]
The p-methoxy group of apixaban connects to S1 pocket of FXa but does not appear to have any interaction with any residues in this region of FXa. The pyrazole N-2 nitrogen atom of apixaban interacts with Gln-192 and the carbonyl oxygen interacts with Gly-216. The phenyl lactam group of apixaban is positioned between Tyr-99 and Phe-174 and due ...
They have a rapid onset and offset of action. This means it is often possible to pause them 12 to 48 hours before surgery and resume them shortly after the surgery. By contrast, warfarin and phenprocoumon are often paused up to a week before surgery, and low-molecular-weight heparins are used to "bridge" the therapy gap, typically for several ...

Andexanet alfa, sold under the brand name Andexxa among others, is an antidote for the medications rivaroxaban and apixaban, when reversal of anticoagulation is needed due to uncontrolled bleeding. [8] It has not been found to be useful for other factor Xa inhibitors. [9] It is given by injection into a vein. [9]
The study found that dabigatran had comparable rates of ischemic stroke or systemic embolism, intracerebral haemorrhage, and all-cause mortality when compared to other anticoagulants like apixaban, edoxaban, and rivaroxaban. Notably, apixaban was associated with a lower risk of gastrointestinal bleeding than dabigatran and the others.
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
