Eliquis
Apixaban
Dose
5 mg orally twice daily (bid) recommended for most patients
Purpose?
To reduce the risk of stroke in patients with nonvalvular atrial fibrillation
Who receives a dose adjustment of 2.5 mg orally twice daily?
Recommended for patients with 2 of the following:

Age-80 years and older
Body weight-60 kg or less
serum Creatinine-1.5 or greater

ABC

Or for patients taking drugs that are strong dual inhibitors of cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp) (eg, ketoconazole, itraconazole, ritonavir, clarithromycin)
Additional dosing considerations
Does not require routine monitoring using INR or other tests of coagulation
Additional dosing considerations
No known dietary restrictions
Additional dosing considerations
Can be taken with or without food
Missed dose
If a dose of Eliquis is not taken at the scheduled time, the dose should be taken as soon as possible on the same day and twice daily administration should be resumed. The dose should not be doubled to make up for a missed dose.
Warning
Discontinuing Eliquis in patients without adequate continuous anticoagulation increases risk of stroke
Contraindications
Active physiological bleeding
Severe hypersensitivity reaction to Eliquis (anaphylactic reactions)
Patients with renal impairment
No dose adjustment required in patients with mild, moderate, or severe renal impairment alone

EXCEPT for those patients who meet the criteria for 2.5 mg twice daily

No data inform use in patients with creatinine clearance less than 15 or on dialysis

Renal excretion accounts for about 27% of total clearance
Patients with hepatic impairment
No dose adjustment required in patients with mild hepatic impairment alone

There is limited clinical experience with Eliquis in patients with moderate hepatic impairment, dosing recommendation cannot be provided

Eliquis is not recommended in patients with severe hepatic impairment
Bleeding risk
Eliquis increases the risk of bleeding and can cause serious, potentially fatal bleeding.
Bleeding risk
Concomitant use of drugs affecting hemostasis increases the risk of bleeding including aspirin and other anti-platelet agents, other anti-coagulants, heparin, thrombolytic agents, SSRIs, SNRIs, and NSAIDs.`
Bleeding risk
Patients should be made aware of signs or symptoms of blood loss and instructed to immediately report to an ER. D/c Eliquis in patients with active pathological hemorrhage.
Surgery and interventions with MODERATE or HIGH risk of unacceptable or clinically significant bleeding
Discontinue Eliquis at least 48 hours prior
Surgery and interventions with LOW risk of bleeding or bleeding in noncritical site and easily controlled
Discontinue Eliquis at least 24 hours prior
Warnings and precautions
There is no established way to reverse the anticoagulant effect of apixaban, which can be expected to persist for about 24 hours after the last dose (about 2 half-lives).
Warnings and precautions
A specific antidote for Eliquis is not available.
Warnings and precautions
Because of high plasma protein binding, Eliquis is not expected to be dialyzable
Warnings and precautions
Use of procoagulant reversal agents such as prothrombin complex concentrate, activated prothrombin complex concentrate, or recombinant factor VIIa may be considered but has not been evaluated in clinical studies.
Warnings and precautions
Activated charcoal reduces absorption of apixaban thereby lowering apixaban plasma concentrations.
Warnings and precautions
Prosthetic Heart Valves: The safety and efficacy of Eliquis has not been studied in patients with prosthetic heart valves and is not recommended in these patients.
Adverse effects
The most common and most serious adverse reactions reported with Eliquis were related to bleeding.
Switching to Eliquis from Warfarin
Discontinue warfarin and start Eliquis when the INR is below 2.0
Switching from Eliquis to warfarin
D/c Eliquis and begin both parenteral anticoagulant and warfarin at the time the next dose would have been taken. D/c the parenteral anticoagulant when INR reaches an acceptable range.
Switching from Eliquis to warfarin
Eliquis affects INR, so that INR measurements during coadministration with warfarin may not be useful for determining the appropriate dose of warfarin.
Switching between Eliquis and anticoagulants other than warfarin
D/c the anticoagulant being taken and begin the other at the next scheduled dose.
Drug interactions
Inhibitors of CYP3A4 and P-gp increase exposure to apixaban and increase the risk of bleeding.
Drug interactions
Inducers of CYP3A4 and P-gp decrease exposure to apixaban and increase the risk of stroke.
Warnings and precautions
Protamine sulfate and vitamin K would not be expected to affect the anticoagulant activity of Eliquis
Warnings and precautions
There is no experience with antifibrinolytic agents (transexamic acid, aminocaproic acid) in individuals receiving Eliquis
Warnings and precautions
There is neither scientific rationale for reversal nor experience with systemic hemostatics (desmopressin and aprotinin) in individuals receiving Eliquis
