              Warnings

              Black Box Warnings

              Spinal/epidural hematoma

              • Epidural or spinal hematomas may occur in patients who are receiving neuraxial anesthesia or undergoing spinal puncture
              • These hematomas may result in long-term or permanent paralysis
              • Monitor patients frequently for signs and symptoms of neurological impairment (eg, numbness or weakness of legs, bowel, or bladder); if neurological compromise is noted, urgent treatment is necessary
              • Consider the benefits and risks before neuraxial intervention in patients who are anticoagulated or to be anticoagulated
              • Management
                • Do not remove an epidural catheter earlier than 72 hr after the last administration of betrixaban
                • Do not administer the next betrixaban dose earlier than 5 hr after catheter removal
                • If traumatic puncture occurs, delay administering betrixaban for 72 hr
              • Factors that can increase the risk include
                • Use of indwelling epidural catheters
                • Concomitant use of other drugs that affect hemostasis (eg, NSAIDs, platelet inhibitors, other anticoagulants)
                • History of traumatic or repeated epidural or spinal punctures
                • History of spinal deformity or spinal surgery
                • Optimal timing between the administration of drug and neuraxial procedures is not known

              Contraindications

              Active pathological bleeding

              Severe hypersensitivity

              Cautions

              Increases bleeding risk and can cause serious and potentially fatal bleeding; promptly evaluate any signs or symptoms of blood loss; there is no established way to reverse betrixaban’s anticoagulant effect, which can persist for at least 72 hr after the last dose; protamine, vitamin K, and tranexamic acid are not expected to reverse betrixaban anticoagulant activity

              Not recommended for use in patients with triple-positive antiphospholipid syndrome (APS); for patients with APS (especially those who are triple positive [positive for lupus anticoagulant, anticardiolipin, and anti–beta 2- glycoprotein I antibodies]), treatment with direct-acting oral anticoagulants has been associated with increased rates of recurrent thrombotic events compared with vitamin K antagonist therapy

              Risk of paralysis with neuraxial anesthesia (see Black Box Warnings)

              Increased bleeding risk with severe renal impairment (see Dosage Modifications)

              Drug interaction overview

              • P-gp substrate
              • Reduce betrixaban dose if coadministration with P-gp inhibitors, owing to increased bleeding risk; avoid coadministration in patients with severe renal impairment receiving concomitant P-gp inhibitors
              • Avoid coadministration with P-gp inducers owing to potential for decreased systemic exposure and pharmacodynamic effects of betrixaban
              • Coadministration with drugs affecting hemostasis increases bleeding risk; examples include aspirin and other antiplatelet agents, other anticoagulants, heparin, thrombolytic agents, SSRIs, SNRIs, and NSAIDs

              Pregnancy

              Pregnancy

              No data exist with use in pregnant women, but treatment is likely to increase risk of hemorrhage during pregnancy and delivery

              Use during pregnancy only if the potential benefit outweighs the potential risk to the mother and fetus

              Animal studies

              • Although betrixaban has not been associated with adverse developmental fetal outcomes in animals, maternal toxicity (ie, hemorrhage) was identified in these studies

              Lactation

              Unknown if distributed in human breast milk

              Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition

              Pregnancy Categories

              A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

              B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

              C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

              D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

              X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

              NA: Information not available.

              Pharmacology

              Mechanism of Action

              Oral factor Xa (FXa) inhibitor that selectively blocks the active site of FXa and does not require a cofactor (eg, antithrombin III) for activity; inhibits free FXa and prothrombinase activity

              By directly inhibiting FXa, betrixaban decreases thrombin generation

              Has no direct effect on platelet aggregation

              Blood coagulation cascade is dependent upon the activation of factor X to FXa via the intrinsic and extrinsic pathways, which play a central role in the blood coagulation cascade

              Absorption

              Bioavailability: 34%

              Peak plasma time: 3-4 hr

              Distribution

              Protein bound: 60%

              Vd: 32 L/kg

              Metabolism

              Unchanged betrixaban is the predominant component found in human plasma

              Two inactive major metabolites formed by CYP-independent hydrolysis comprise the other components in plasma, accounting for 15-18% of the circulating drug-related material

              Elimination

              Half-life: 19-27 hr

              Excretion: 85% feces; 11% urine
