Which drugs are factor Xa inhibitors?

Factor Xa Inhibitors

• apixaban.
• Arixtra.
• betrixaban.
• Bevyxxa.
• edoxaban.
• Eliquis.
• fondaparinux.
• rivaroxaban.

Are factor Xa inhibitors anticoagulants?

Factor Xa inhibitors are a type of anticoagulant (blood thinning drugs) that work by binding selectively and reversibly to the clotting factor Xa. Factor Xa plays a crucial role in the blood clotting mechanism when you get an injury by forming a mesh to prevent loss of blood.

Which anticoagulant has the greatest efficacy on factor Xa?

Betrixaban. Betrixaban (PRT-054021) specifically and reversibly inhibits factor Xa with a Ki of 0.117 nmol/L. It has a bioavailability of 47 %, a half-life of 19 h, and is excreted almost unchanged in bile. Betrixaban has demonstrated antithrombotic activity in animal models and in human blood.

What Happens When factor Xa is inhibited?

Inhibition of Xa leads to a significant reduction in thrombin and ultimately clot formation [Turpie, 2007].

Is eliquis a factor Xa inhibitor?

ELIQUIS is an oral, reversible factor Xa inhibitor indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation.

Is Heparin a factor Xa inhibitor?

Heparin acts as an anticoagulant by activating antithrombin and accelerating the rate at which it inhibits thrombin, factor (f) Xa and multiple other upstream coagulation enzymes.

Is Eliquis a factor Xa inhibitor?

When do you use factor Xa?

Coagulation factor Xa is used to treat uncontrolled bleeding in people who take the anticoagulants rivaroxaban (Xarelto) and apixaban (Eliquis). Coagulation factor Xa was approved by the US Food and Drug Administration (FDA) on an “accelerated” basis.

Which anticoagulant is a direct inhibitor of factor Xa?

Apixaban. Apixaban is a direct factor Xa inhibitor. In the APPRAISE-2 trial,63 5 mg twice daily (the dose used to prevent thromboembolic complications in ACS patients) was compared with placebo, in addition to standard therapy, in patients with recent ACS.

What clotting factors does apixaban affect?

Apixaban is a highly selective direct factor Xa inhibitor, blocking the propagation phase of the coagulation cascade. It exerts its effect on both free and clot-bound factor Xa.

Why is apixaban better than warfarin?

The blood-thinner apixaban is less likely to cause major bleeding than warfarin. People who take apixaban to prevent blood clots are less likely to suffer major bleeding complications than those taking warfarin.

What is the best blood clotting factor 10A inhibitor?

Blood Clotting Factor 10a Inhibitor Direct factor Xa inhibitors are now available (i.e., rivaroxaban), which can be given as monotherapy (without the need for a heparin bridge) and have been shown to be noninferior to the combination of LMWH and VKA. From: Abernathy’s Surgical Secrets (Seventh Edition), 2018

Factor Xa inhibitors have predictable anticoagulant effects and do not require routine monitoring, unlike some other anticoagulants. Apixaban, edoxaban, fondaparinux, and rivaroxaban are all Factor Xa inhibitors.

What is the prophylactic range for anti factor Xa?

Prophylactic anti-factor Xa ranges. In acutely ill medical patients, average AFXa levels at Day 10 were 0.21 and 0.41 when 20 mg and 40 mg enoxaparin daily were administered respectively. 20 The prophylactic range is defined to be between 0.2-0.5 IU/mL by Weitz, 21 although the reference cited only reported therapeutic AFXa levels.

Is apixaban a factor Xa inhibitor?

Apixaban is a direct factor Xa inhibitor. In the APPRAISE-2 trial, 63 5 mg twice daily (the dose used to prevent thromboembolic complications in ACS patients) was compared with placebo, in addition to standard therapy, in patients with recent ACS.
