Dosing & Uses
Dosage Forms & Strengths
injectable solution
- 100mg/mL
ready-to-use injectable
- 50mg/50mL 0.9% NaCl
- 125mg/125mL 0.9% NaCl
- 250mg/2.5mL 0.9% NaCl
Thrombocytopenia
Indicated as an anticoagulant for prophylaxis or treatment of thrombosis in patients with heparin-induced thrombocytopenia
Initial: 2 mcg/kg/min IV continuous infusion over 1-3 hours until steady-state aPTT is 1.5-3 times initial baseline value
Not to exceed infusion rate of 10 mcg/kg/min
Dosing considerations
- Check aPTT and adjust dose until target aPTT is achieved
Percutaneous Coronary Intervention
Indicated as an anticoagulant in patients with or at risk for heparin-induced thrombocytopenia undergoing percutaneous coronary intervention (PCI)
Initial: 25 mcg/kg/min IV infusion, AND
A bolus of 350 mcg/kg IV over 3-5 minutes via large-bore IV line
Check activated clotting time (ACT) 5-10 minutes after bolus dose is completed; procedure may proceed if ACT is >300 seconds
If ACT is <300 seconds, administer additional IV bolus dose of 150 mcg/kg, increase infusion dose to 30 mcg/kg/min, and check ACT 5-10 minutes later
If ACT >450 seconds, decrease infusion rate to 15 mcg/kg/min, and check ACT 5-10 minutes later
After therapeutic ACT (300-450 sec) achieved, continue this infusion dose for duration of procedure
Dosing Modifications
Hepatic impairment
- Approximately 4-fold decrease in clearance relative to those with normal hepatic function, so dosing modification warranted; monitor aPTT and adjust dosage as clinically indicated
- Thrombocytopenia: Decrease initial dose to 0.5 mcg/kg/min IV
- PCI: For patients with hepatic impairment undergoing PCI and who have HIT or are at risk for HIT, carefully titrate argatroban until desired level of anticoagulation achieved; use of drug in PCI patients with clinically significant hepatic disease or AST/ALT levels ≥3 times the upper limit of normal should be avoided

Active major bleeding
Cautions
Monitor therapy with aPTT
Use caution in hepatic impairment; achievement of steady-state aPTT levels may take longer and require more argatroban dose adjustments in patients with hepatic impairment compared to patients with normal hepatic function; avoid use of high doses in patients undergoing percutaneous coronary intervention (PCI) who have clinically significant hepatic disease
Patients with illnesses that reduce clearance may require dose reduction
Safety and efficacy of concomitant administration with thrombolytic agents not established
Discontinue parenteral anticoagulant therapy prior to initiating treatment
Risk of hemorrhage
- Hemorrhage can occur at any site in the body
- Intracranial and retroperitoneal hemorrhage reported
- Unexplained fall in hematocrit or blood pressure after lumbar puncture, spinal anesthesia, major surgery (especially involving the brain, spinal cord, or eye) associated with hemorrhage;
- Hematologic conditions may increase risk of hemorrhage, such as congenital or acquired bleeding disorders, and gastrointestinal lesions such as ulcerations
- Concomitant use of argatroban with antiplatelet agents, thrombolytics, and other anticoagulants may increase risk of bleeding
Pregnancy & Lactation
Pregnancy
Limited data from published literature and postmarketing reports do not suggest an association between argatroban and adverse fetal developmental outcomes; there are risks to mother associated with untreated thrombosis in pregnancy and a risk of hemorrhage in mother and fetus associated with use of anticoagulants
Pregnancy confers an increased risk for 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
Use of anticoagulants, including argatroban, may increase risk of bleeding in fetus and neonate; monitor neonates for bleeding
Pregnant women should be carefully monitored for evidence of excessive bleeding or unexpected changes in coagulation parameters during labor or delivery
Animal data
- In animal reproduction studies, there was no evidence of adverse developmental outcomes with intravenous administration of argatroban during organogenesis in rats and rabbits at doses up to 0.3- and 0.2-times, respectively, the maximum recommended human dose (MHRD)
Lactation
There are no data on presence in human milk, or effects on milk production; it is present in rat milk; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from therapy or from 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
Competitive, direct thrombin inhibitor that reversibly binds to thrombin active site; thrombin enables fibrinogen conversion to fibrin during the coagulation cascade

Liver
Elimination
Half-life: 39-51 min
