🚫 Contraindications ›

4 CONTRAINDICATIONS Apixaban tablets are contraindicated in patients with the following conditions: • Active pathological bleeding [see Warnings and Precautions ( 5.2 ) and Adverse Reactions( 6.1) ] • Severe hypersensitivity reaction to apixaban (e.g., anaphylactic reactions) [see Adverse Reactions ( 6.1 )] Active pathological bleeding ( 4 ) Severe hypersensitivity to apixaban ( 4 )

⚠️ Warnings & Precautions ›

5 WARNINGS AND PRECAUTIONS Apixaban can cause serious, potentially fatal, bleeding. Promptly evaluate signs and symptoms of blood loss. An agent to reverse the anti-factor Xa activity of apixaban is available ( 5.2 ) Prosthetic heart valves: Apixaban use not recommended. ( 5.4 ) Increased Risk of Thrombosis in Patients with Triple Positive Antiphospholid Syndrome: Apixaban Tablets are use not recommended. ( 5.6 )

5.1 Increased Risk of Thrombotic Events after Premature Discontinuation Premature discontinuation of any oral anticoagulant, including apixaban tablets, in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. An increased rate of stroke was observed during the transition from apixaban tablets to warfarin in clinical trials in atrial fibrillation patients. If apixaban tablets are discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant [see Dosage and Administration ( 2.4) and Clinical Studies ( 14.1 )].

5.2 Bleeding Apixaban tablets increases the risk of bleeding and can cause serious, potentially fatal, bleeding [see Dosage and Administration ( 2.1 ) and Adverse Reactions ( 6.1 )]. Concomitant use of drugs affecting hemostasis increases the risk of bleeding. These include aspirin and other antiplatelet agents, other anticoagulants, heparin, thrombolytic agents, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs) [see Drug Interactions ( 7.3) ]. Advise patients of signs and symptoms of blood loss and to report them immediately or go to an emergency room. Discontinue apixaban tablets in patients with active pathological hemorrhage. Reversal of Anticoagulant Effect An agent to reverse the anti-factor Xa activity of apixaban is available. The pharmacodynamic effect of apixaban tablets can be expected to persist for at least 24 hours after the last dose, ... [See full FDA label]

🔴 Adverse Reactions ›

6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in greater detail in other sections of the prescribing information. • Increased risk of thrombotic events after premature discontinuation [see Warnings and Precautions ( 5.1 )] • Bleeding [see Warnings and Precautions ( 5.2 )] • Spinal/epidural anesthesia or puncture [see Warnings and Precautions ( 5.3 )] Most common adverse reactions (>1%) are related to bleeding.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Reduction of Risk of Stroke and Systemic Embolism in Patients with Nonvalvular Atrial Fibrillation The safety of apixaban tablets was evaluated in the ARISTOTLE and AVERROES studies [see Clinical Studies ( 14 )] , including 11,284 patients exposed to apixaban tablets 5 mg twice daily and 602 patients exposed to apixaban tablets 2.5 mg twice daily. The duration of apixaban tablets exposure was ≥12 months for 9375 patients and ≥24 months for 3369 patients in the two studies. In ARISTOTLE, the mean duration of exposure was 89 weeks (>15,000 patient-years). In AVERROES, the mean duration of exposure was approximately 59 weeks (>3000 patient-years). The most common reason for treatment discontinuation in both studies was for bleeding-related adverse reactions; in ARISTOTLE this occurred in 1.7% and 2.5% of patients treated with apixaban tablets and warfarin, respectively, and in AVERROES, in 1.5% and 1.3% on apixaban tablets and aspirin, respectively. Bleeding in Patients with Nonvalvular Atrial Fibrillation in ARISTOTLE and AVERROES Tables 1 and 2 show the number of patients e... [See full FDA label]

💊 Drug Interactions ›

7 DRUG INTERACTIONS Apixaban is a substrate of both CYP3A4 and P-gp. Inhibitors of CYP3A4 and P-gp increase exposure to apixaban and increase the risk of bleeding. Inducers of CYP3A4 and P-gp decrease exposure to apixaban and increase the risk of stroke and other thromboembolic events. Combined P-gp and strong CYP3A4 inhibitors increase blood levels of apixaban. Reduce apixaban dose or avoid coadministration. ( 2.5 , 7.1 , 12.3 ) Simultaneous use of combined P-gp and strong CYP3A4 inducers reduces blood levels of apixaban: Avoid concomitant use. ( 7.2 , 12.3 )

7.1 Combined P-gp Strong CYP3A4 Inhibitors For patients receiving apixaban 5 mg or 10 mg twice daily, the dose of apixaban should be decreased by 50% when coadministered with drugs that are combined P-gp and strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir) [see Dosage and Administration (2.5) and Clinical Pharmacology ( 12.3) ]. For patients receiving apixaban at a dose of 2.5 mg twice daily, avoid coadministration with combined P-gp and strong CYP3A4 inhibitors [see Dosage and Administration ( 2.5 ) and Clinical Pharmacology ( 12.3 )]. Clarithromycin Although clarithromycin is a combined P-gp and strong CYP3A4 inhibitor, pharmacokinetic data suggest that no dose adjustment is necessary with concomitant administration with apixaban [see Clinical Pharmacology ( 12.3) ].

7.2 Combined P-gp Strong CYP3A4 Inducers Avoid concomitant use of apixaban tablets with combined P-gp and strong CYP3A4 Inducers (e.g., rifampin, carbamazepine, phenytoin, St. John’s wort) because such drugs will decrease exposure to apixaban [see Clinical Pharmacology ( 12.3 )].

7.3 Anticoagulants and Antiplatelet Agents Coadministration of antiplatelet agents, fibrinolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding. APPRAISE-2, a placebo-controlled clinical trial of apixaban in high-risk, post-acute coronary syndrome patients treated with aspirin or the combination of aspirin and clopidogre...

🤰 Pregnancy ›

8.1 Pregnancy Risk Summary The limited available data on apixaban tablets use in pregnant women are insufficient to inform drug-associated risks of major birth defects, miscarriage, or adverse developmental outcomes. Treatment may increase the risk of bleeding during pregnancy and delivery. In animal reproduction studies, no adverse developmental effects were seen when apixaban was administered to rats (orally), rabbits (intravenously) and mice (orally) during organogenesis at unbound apixaban exposure levels up to 4, 1 and 19 times, respectively, the human exposure based on area under plasma-concentration time curve (AUC) at the Maximum Recommended Human Dose (MRHD) of 5 mg twice daily. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Pregnancy confers an increased risk of thromboembolism that is higher for women with underlying thromboembolic disease and certain high-risk pregnancy conditions. Published data describe that women with a previous history of venous thrombosis are at high risk for recurrence during pregnancy. Fetal/Neonatal adverse reactions Use of anticoagulants, including apixaban, may increase the risk of bleeding in the fetus and neonate. Labor or delivery All patients receiving anticoagulants, including pregnant women, are at risk for bleeding. Apixaban tablets use during labor or delivery in women who are receiving neuraxial anesthesia may result in epidural or spinal hematomas. Consider use of a shorter acting anticoagulant as delivery approaches [see Warnings and Precautions ( 5.3 )]. Data Animal Data No developmental toxicities were observed w... [See full FDA label]

🤱 Nursing / Lactation ›

8.3 Females and Males of Reproductive Potential Females of reproductive potential requiring anticoagulation should discuss pregnancy planning with their physician. The risk of clinically significant uterine bleeding, potentially requiring gynecological surgical interventions, identified with oral anticoagulants including apixaban should be assessed in females of reproductive potential and those with abnormal uterine bleeding.

👶 Pediatric Use ›

8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.

👴 Geriatric Use ›

8.5 Geriatric Use Of the total subjects in the ARISTOTLE and AVERROES clinical studies, >69% were 65 years of age and older, and >31% were 75 years of age and older. In the ADVANCE-1, ADVANCE-2, and ADVANCE-3 clinical studies, 50% of subjects were 65 years of age and older, while 16% were 75 years of age and older. In the AMPLIFY and AMPLIFY-EXT clinical studies, >32% of subjects were 65 years of age and older and >13% were 75 years of age and older. No clinically significant differences in safety or effectiveness were observed when comparing subjects in different age groups.

🔬 Mechanism of Action ›

12.1 Mechanism of Action Apixaban is a selective inhibitor of FXa. It does not require antithrombin III for antithrombotic activity. 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.

📊 Pharmacokinetics ›

12.3 Pharmacokinetics Apixaban demonstrates linear pharmacokinetics with dose-proportional increases in exposure for oral doses up to 10 mg. Absorption The absolute bioavailability of apixaban is approximately 50% for doses up to 10 mg of apixaban. Food does not affect the bioavailability of apixaban. Maximum concentrations (Cmax) of apixaban appear 3 to 4 hours after oral administration of apixaban. At doses ≥25 mg, apixaban displays dissolution-limited absorption with decreased bioavailability. Following oral administration of 10 mg of apixaban as 2 crushed 5 mg tablets suspended in 30 mL of water, exposure was similar to that after oral administration of 2 intact 5 mg tablets. Following oral administration of 10 mg of apixaban as 2 crushed 5 mg tablets mixed with 30 g of applesauce, the Cmax and AUC were 20% and 16% lower, respectively, when compared to administration of 2 intact 5 mg tablets. Following administration of a crushed 5 mg apixaban tablet that was suspended in 60 mL D5W and delivered through a nasogastric tube, exposure was similar to that seen in other clinical trials involving healthy volunteers receiving a single oral 5 mg tablet dose. Distribution Plasma protein binding in humans is approximately 87%. The volume of distribution (Vss) is approximately 21 liters. Metabolism Approximately 25% of an orally administered apixaban dose is recovered in urine and feces as metabolites. Apixaban is metabolized mainly via CYP3A4 with minor contributions from CYP1A2, 2C8, 2C9, 2C19, and 2J2. O-demethylation and hydroxylation at the 3-oxopiperidinyl moiety are the major sites of biotransformation. Unchanged apixaban is the major drug-related component in human plasma; there are no active circulating metabolites. Elimination Apixaban is eliminated in both urine and feces. Renal excretion accounts for about 27% of total clearance. Biliary and direct intestinal excretion contributes to elimination of apixaban in the feces. Apixaban has a total clearance of appr... [See full FDA label]

☠️ Overdosage ›

10 OVERDOSAGE Overdose of apixaban tablets increases the risk of bleeding [see Warnings and Precautions ( 5.2 )]. In controlled clinical trials, orally administered apixaban in healthy subjects at doses up to 50 mg daily for 3 to 7 days (25 mg twice daily for 7 days or 50 mg once daily for 3 days) had no clinically relevant adverse effects. In healthy subjects, administration of activated charcoal 2 and 6 hours after ingestion of a 20-mg dose of apixaban reduced mean apixaban AUC by 50% and 27%, respectively. Thus, administration of activated charcoal may be useful in the management of apixaban overdose or accidental ingestion. An agent to reverse the anti-factor Xa activity of apixaban is available.
