Indications
- prophylaxis for venous thromboembolism after knee replacement or hip replacement[10]
- embolic stroke prophylaxis for atrial fibrillation[3][8]
- better than warfarin[4][6]
- annual risk of death lower than with warfarin (5.2% vs 8.5%)[15]
- appears to be direct anticoagulant of choice[19]
- prevention & treatment of deep vein thrombosis & venous thromboembolism[7][9][13]
- more effective with less major bleeding than rivaroxaban[26]
- prevention of venous thromboembolism in patients with cancer[24]
- useful for prevention of pulmonary embolism in patients starting chemotherapy (NNT = 17)[24]
* safe & effective in the elderly[12]
Contraindications
- continued use of apixaban as thromboprophylaxis after hospitalization of medically ill patients[5]
- pregnancy
- valvular heart disease
- morbid obesity (BMI >40 mg/kg)[27]
- high-risk antiphospholipid antibody syndrome[14]
- osteoporosis (GRS11: due to increased fracture risk relative to warfarin)[27]
- ref[38] concludes decreased fracture risk relative to warfarin
* apixaban ok in ESRD with close monitoring[14] (see[22][31])
Dosage
- DVT prophylaxis
- DVT treatment
- prophylaxis for embolic stroke with atrial fibrillation
- 2.5 mg PO BID age >= 80 years, body weight <= 60 kg, or serum creatinine >= 1.5 mg/dL, (2 of 3)[16]
- apixaban beneficial & safe in all weight groups[28]
Tabs: 5 mg, 2.5 mg
* stop 24-48 hours prior to surgery[27] (see perioperative anticoagulation)
Dosage adjustment in renal failure
- 2.5 mg PO BID with serum creatinine >= 1.5 mg/dL AND
- lack of efficacy with eGFR < 25 mL/min[30]
- apixaban with 5-fold higher risk of stroke when underdosed[20]
- dabigatran & rivaroxaban not associated with higher risk of stroke when underdosed[20]
- in patients with ESRD, apixaban associated with lower risk of major bleeding than warfarin, & with reductions in thromboembolism & mortality (dose 5 mg BID)[22][34]
Pharmacokinetics
- renal elimination: 25%
- metabolized in the liver by CYP3A4
- time to maximum concentration: 3 hours
- 1/2life: 9-14 hours
- protein binding: 87%[14]
Monitor
- none required
Adverse effects
- less bleeding than enoxaparin or warfarin[21]
- apixaban with lowest risk of GI bleed among direct oral anticoagulants[17][21][25][35]
- lowest risk of GI bleed in patients > 75 years
- risk < 1/2 that with rivaroxaban (highest risk)
- rates of ischemic stroke, systemic embolism, intracranial hemorrhage & all-cause mortality similar for apixaban, dabigatran, edoxaban, & rivaroxaban in patients with atrial fibrillaton including for patients >= 80 years & those with chronic kidney disease[35]
- coadministration of proton pump inhibitor may further decrease risk of upper GI bleed[25]
- lowest risk of GI bleed in patients > 75 years
- among Medicare recipients with atrial fibrillation >= 65 years, apixaban is associated with lower risk of major ischemic events & major hemorrhage than rivaroxaban[33]
- apixaban 5 mg PO BID may not increase risk of hemorrhagic stroke[23]
- doses of apixaban < 10 mg/day associated with increased mortality ~30% relative to warfarin[21]
- higher risk of ischemic stroke in nursing home residents than warfarin (RR=1.9), but lower risk of bleeding (RR=0.7)[32]
- andexanet reverses factor Xa inhibition
- 4 factor prothrombin complex concentrate effective for 70% of hemorrhages[18]
- drug adverse effects of direct oral anticoagulants
- drug adverse effects of anticoagulants
- drug adverse effects of antithrombotic agent(s)
Drug interactions
- strong dual inhibitors of CYP3A4 & P-glycoprotein increase levels of apixaban
- drug interaction(s) of direct oral anticoagulants (DOAC) with NSAIDs
- drug interaction(s) of oral anticoagulants with selective serotonin reuptake inhibitor (SSRI)
- drug interaction(s) of diltiazem with apixaban
- drug interaction(s) of apixaban with NSAIDs
- drug interaction(s) of aspirin, P2Y12 inhibitors & anticoagulants
Laboratory
Mechanism of action
- direct inhibitor of factor Xa
Notes
- rivaroxaban is also a small molecule inhibitor of factor Xa administered orally
- 1st generic FDA-approved Dec 2019[29]
- Manufacturer's website offers free 30 day trial & $10 copay options[37]
