Argatroban (Argatra®) is a reversible, monovalent direct thrombin inhibitor available only as an infusion solution.

Clinical significance

Argatroban is approved to continue anticoagulation in adults with type II heparin-induced thrombocytopenia (HIT).
The elimination of argatroban and its metabolites occurs mainly via the liver (65.4 ± 7.1%) less than the kidney (21.8 ± 5.8%). Thus, argatroban does not accumulate in cases of renal insufficiency. There is no antidote.


  • Monitoring of anticoagulation using Argatra, while using a heart-lung machine or during percutaneous coronary intervention (PCI). With the doses of more than 1?g/ml argatroban, which are usual on the heart-lung machine or in PCI, the argatroban concentration/aPTT-time curve shows an asymptotic course, not a linear course.
  • Measuring the coagulation inhibition in connection with argatroban can be useful in order to avoid excessive high exposure to argatroban if additional risk factors are present.
