What is the mode of action of apixaban?

What is the mode of action of apixaban?

Mechanism of Action Apixaban inhibits free and clot-bound FXa, and prothrombinase activity. Apixaban has no direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. By inhibiting FXa, apixaban decreases thrombin generation and thrombus development.

How does apixaban work in the body?

Apixaban blocks the clotting factor called factor Xa, which will keep clots from forming and can prevent the clots from getting larger. Apixaban does not break up clots that already exist. Apixaban begins to reduce blood clotting within a few hours after taking the first dose.

What is the onset of action of Eliquis?

How does apixaban work on clotting cascade?

Apixaban inhibits activated Factor X in the coagulation cascade to prevent clot formation and has been approved by the FDA to treat and prevent deep vein thrombosis and pulmonary embolism as well as to prevent strokes in atrial fibrillation patients.

Warfarin requires routine monitoring of the international normalized ratio (INR) through blood tests, while Eliquis does not require regular INR monitoring. The INR measures how quickly the blood clots. If the blood clots too quickly, there is a higher risk for blood clots.

Does apixaban affect PTT?

Rivaroxaban and apixaban have a peak effect 1-3 hours after oral intake and if PT/INR and aPTT testing is done within this time period, this can lead to elevated PT/INR and aPTT.

Why is apixaban given?

Apixaban is used help prevent strokes or blood clots in people who have atrial fibrillation (a condition in which the heart beats irregularly, increasing the chance of clots forming in the body and possibly causing strokes) that is not caused by heart valve disease.
