Pharmacology

Mechanism of Action

A direct, highly-selective thrombin inhibitor. Reversibly binds to the active thrombin site of free and clot-associated thrombin. Inhibits fibrin formation; activation of coagulation factors V, VIII, and XIII; activation of protein C; and platelet aggregation.

Pharmacokinetics/Pharmacodynamics

Distribution

174 mL/kg

Metabolism

Hepatic via hydroxylation and aromatization (major route). Metabolism via CYP3A4/5 (minor route) to four metabolites. Unchanged argatroban is the major plasma component. Plasma concentration of metabolite M1 is 0% to 20% of the parent drug and is three- to fivefold weaker.

Excretion

Feces (~65%; 14% unchanged); urine (~22%; 16% unchanged); low quantities of metabolites M2-4 in urine

Clearance:

Pediatric patients (seriously ill): 0.16 L/kg/hour; 50% lower than healthy adults

Pediatric patients (seriously ill with elevated bilirubin due to hepatic impairment or cardiac complications; n=4): 0.03 L/kg/hour; 80% lower than pediatric patients with normal bilirubin

Adult: 0.31 L/kg/hour (5.1 mL/kg/minute); hepatic impairment: 1.9 mL/kg/minute

Onset of Action

Immediate

Time to Peak

Steady-state: 1 to 3 hours

Half-Life Elimination

39 to 51 minutes; Hepatic impairment: 181 minutes

Protein Binding

Albumin: 20%; alpha1-acid glycoprotein: 34%

Use: Labeled Indications

Heparin-induced thrombocytopenia: Prophylaxis or treatment of thrombosis in adults with heparin-induced thrombocytopenia (HIT).

Percutaneous coronary intervention: As an anticoagulant for percutaneous coronary intervention (PCI) in adults who have or are at risk of developing HIT.

Use: Off Label

Extracorporeal circuit patency of continuous renal replacement therapy (CRRT) in critically-ill patients with HIT (maintenance)c

Data from a limited number of patients studied suggest that prefilter administration of argatroban may be beneficial for the maintenance of extracorporeal circuit patency of continuous renal replacement therapy (CRRT) in critically-ill patients with HIT Link 2009. Additional data may be necessary to further define the role of argatroban in this setting.

Contraindications

Hypersensitivity to argatroban or any component of the formulation; major bleeding.

Canadian labeling: Additional contraindications (not in US labeling): Hereditary fructose intolerance.

Dosage and Administration

Dosing: Adult

Heparin-induced thrombocytopenia (HIT): Continuous IV infusion:

Initial dose: 2 mcg/kg/minute

Note: Critically-ill patients with normal hepatic function have become excessively anticoagulated with FDA-approved or lower starting doses of argatroban. Doses between 0.15 to 1.3 mcg/kg/minute were required to maintain aPTTs in the target range (Reichert 2003). In a prospective observational study of critically-ill patients with multiple organ dysfunction (MODS) and suspected or proven HIT, an initial infusion dose of 0.2 mcg/kg/minute was found to be sufficient and safe in this population (Beiderlinden 2007). Consider reducing starting dose to 0.2 mcg/kg/minute in critically-ill patients with MODS defined as a minimum number of two organ failures. Another report of a cardiac patient with anasarca secondary to acute renal failure had a reduction in argatroban clearance similar to patients with hepatic dysfunction. Reduced clearance may have been due to reduced liver perfusion (de Denus 2003). The American College of Chest Physicians has recommended an initial infusion rate of 0.5 to 1.2 mcg/kg/minute for patients with heart failure, MODS, severe anasarca, or postcardiac surgery (Linkins 2012).

Obesity: Pharmacokinetics and pharmacodynamics have not been evaluated prospectively in obese patients; however, retrospective data suggest using actual body weight to dose and that adjustment of initial dose is unnecessary in obesity (BMI up to 51 kg/m2) (Rice 2007).

Maintenance dose: Patient may not be at steady-state but measure aPTT after 2 hours; adjust dose until the steady-state aPTT is 1.5 to 3 times the initial baseline value, not exceeding 100 seconds; dosage should not exceed 10 mcg/kg/minute

Conversion to oral anticoagulant: Because there may be a combined effect on the INR when argatroban is combined with warfarin, loading doses of warfarin should not be used. Warfarin therapy should be started at the expected daily dose.

Patients receiving ≤2 mcg/kg/minute of argatroban: Argatroban therapy can be stopped when the INR is >4 on combined warfarin and argatroban therapy; repeat INR measurement in 4 to 6 hours; if INR is below therapeutic level, argatroban therapy may be restarted. Repeat procedure daily until desired INR on warfarin alone is obtained.

Patients receiving >2 mcg/kg/minute of argatroban: Reduce dose of argatroban to 2 mcg/kg/minute; measure INR for argatroban and warfarin 4 to 6 hours after dose reduction; argatroban therapy can be stopped when the INR on warfarin and argatroban combined therapy is >4. Repeat INR measurement in 4 to 6 hours; if INR is below therapeutic level, argatroban therapy may be restarted. Repeat procedure daily until desired INR on warfarin alone is obtained.

Note: The American College of Chest Physicians suggests monitoring chromogenic factor X assay when transitioning from argatroban to warfarin (Garcia 2012) or overlapping administration of warfarin for a minimum of 5 days until INR is within target range; recheck INR after anticoagulant effect of argatroban has dissipated (Guyatt 2012). Factor X levels <45% have been associated with INR values >2 after the effects of argatroban have been eliminated (Arpino 2005).

Prefilter administration for continuous renal replacement therapy (CRRT) in critically-ill patients with HIT (off-label use; Link 2009): 0.1 to 1.5 mcg/kg/minute. Note: Loading dose of 100 mcg/kg was administered during clinical trial; however, this may be unnecessary.

Percutaneous coronary intervention (PCI): IV:

Initial: Begin infusion of 25 mcg/kg/minute and administer bolus dose of 350 mcg/kg (over 3 to 5 minutes). ACT should be checked 5 to 10 minutes after bolus infusion; proceed with procedure if ACT >300 seconds.

Obesity: Pharmacokinetics and pharmacodynamics have not been evaluated prospectively in obese patients; however, retrospective data suggest using actual body weight to dose and that adjustment of initial dose is unnecessary in obesity (BMI up to 51 kg/m2) (Hursting 2008).

Following initial bolus:

ACT <300 seconds: Give an additional 150 mcg/kg bolus, and increase infusion rate to 30 mcg/kg/minute (recheck ACT in 5 to 10 minutes)

ACT >450 seconds: Decrease infusion rate to 15 mcg/kg/minute (recheck ACT in 5 to 10 minutes)

Once a therapeutic ACT (300 to 450 seconds) is achieved, infusion should be continued at this dose for the duration of the procedure.

If dissection, impending abrupt closure, thrombus formation during PCI, or inability to achieve ACT >300 seconds: An additional bolus of 150 mcg/kg, followed by an increase in infusion rate to 40 mcg/kg/minute may be administered (recheck ACT after each additional bolus or change in infusion rate).

Note: Post-PCI anticoagulation, if required, may be achieved by continuing infusion at a reduced dose of 2 mcg/kg/minute, with close monitoring of aPTT; adjust infusion rate as needed. Recheck ACT after each additional bolus or change in infusion rate.

Dosing: Geriatric

Refer to adult dosing.

Dosing: Pediatric

Heparin-induced thrombocytopenia: Limited data available: Infants and Children ≤16 years: Note: Titration of maintenance dose must consider multiple factors including current argatroban dose, current aPTT, target aPTT, and clinical status of the patient. For specific uses, required maintenance dose is highly variable between patients. During the course of treatment, patient's dosing requirements may change as clinical status changes; critically ill patients and patients with hepatic dysfunction require lower dose; frequent dosage adjustments may be required in critical patients to maintain desired anticoagulant activity (Alsoufi 2004; Boshkov 2006; Keegan 2009). If argatroban therapy is used concurrently with or following FFP or a thrombolytic, some centers decrease dose by half (Alsoufi 2004).

Continuous IV infusion:

Initial dose: 0.75 mcg/kg/minute (Madabushi 2011)

Maintenance dose: Measure aPTT after 2 hours; adjust dose until the steady-state aPTT is 1.5 to 3 times the initial baseline value, not exceeding 100 seconds; adjust in increments of 0.1 to 0.25 mcg/kg/minute for normal hepatic function; reduce dose in hepatic impairment.

Note: A lower initial infusion rate may be needed in other pediatric patients with reduced clearance of argatroban (eg, patients with heart failure, multiple organ system failure, severe anasarca, postcardiac surgery or hepatic impairment). This precaution is based on adult studies of patients with these disease states who had reduced argatroban clearance.

Conversion to oral anticoagulant: Because there may be a combined effect on the INR when argatroban is combined with warfarin, loading doses of warfarin should not be used. Warfarin therapy should be started at the expected daily dose. Once combined INR on warfarin and argatroban is >4, stop argatroban. Repeat INR measurement in 4 to 6 hours; if INR is below therapeutic level, argatroban therapy may be restarted. Repeat procedure daily until desired INR on warfarin alone is obtained. Another option is to use factor X levels to monitor the effect of warfarin anticoagulation. When factor X level is <0.3, warfarin is considered therapeutic and at which time argatroban can be discontinued (Alsoufi 2004; Boshkov 2006).

Dosing: Obesity

Refer to adult dosing.

Test Interactions

Argatroban may elevate PT/INR levels in the absence of warfarin. If warfarin is started, initial PT/INR goals while on argatroban may require modification. The American College of Chest Physicians suggests monitoring chromogenic factor X assay when transitioning from argatroban to warfarin (Garcia, 2012) or overlapping administration of warfarin for a minimum of 5 days until INR is within target range; recheck INR after anticoagulant effect of argatroban has dissipated (Guyatt, 2012). Factor Xa levels <45% have been associated with INR values >2 after the effects of argatroban have been eliminated (Arpino, 2005).

Adverse Reactions

As with all anticoagulants, bleeding is the major adverse effect of argatroban. Hemorrhage may occur at virtually any site. Risk is dependent on multiple variables, including the intensity of anticoagulation and patient susceptibility.

Warnings/Precautions

Concerns related to adverse effects:

  • Bleeding: The most common complication is bleeding and can occur at any site in the body. Use extreme caution in patients with hematologic conditions associated with increased bleeding (eg, congenital or acquired bleeding disorders, GI lesions); recent puncture of large vessels or organ biopsy; spinal anesthesia; immediately following lumbar puncture; recent cerebrovascular accident (CVA), stroke, intracerebral surgery, or other neuraxial procedure; severe hypertension; renal impairment; recent major surgery; recent major bleeding (intracranial, GI, intraocular, or pulmonary). Monitor for signs and symptoms of bleeding.
  • Hypersensitivity: Airway, skin, and generalized hypersensitivity reactions have been reported.

Disease-related concerns:

  • Hepatic impairment: Use with caution in patients with hepatic impairment; dosage reduction is necessary; may require >4 hours to achieve full reversal of anticoagulant effects. Avoid use during PCI in patients with clinically significant hepatic impairment or elevations of ALT/AST ≥3 times ULN (has not been studied).

Concurrent drug therapy issues:

  • Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

  • Critically ill patients: Use with caution in critically-ill patients; reduced clearance may require dosage reduction.

Monitoring Parameters

Monitor hemoglobin, hematocrit, signs and symptoms of bleeding.

HIT: Obtain baseline aPTT prior to start of therapy. Patient may not be at steady-state but check aPTT 2 hours after start of therapy to adjust dose, keeping the steady-state aPTT 1.5 to 3 times the initial baseline value (not exceeding 100 seconds).

PCI: Monitor ACT before dosing, 5 to 10 minutes after bolus dosing, and after any change in infusion rate and at the end of the procedure. Additional ACT assessments should be made every 20 to 30 minutes during extended PCI procedures.

Pregnancy

Pregnancy Considerations

Information related to argatroban in pregnancy is limited. Use of parenteral direct thrombin inhibitors in pregnancy should be limited to those women who have severe allergic reactions to heparin, including heparin-induced thrombocytopenia, and who cannot receive danaparoid (Guyatt 2012).
