Q; Bivalirudin (Angiomax) is removed by hemodialysis?
Bivalirudin is a parenteral direct thrombin inhibitor. It is a hirudin analog which is a mainstay of treatment in Heparin-Induced Thrombocytopenia (HIT). Bivalirudin may get removed by continuous renal replacement therapy (CRRT) and hemodialysis (HD), a very common scenario in ICU patients.
This is an important clinical consideration as close monitoring of PTT is required to keep anticoagulation within the therapeutic range. In such renal patients, dose can range widely anywhere from 0.01 to 0.07 mg/kg per hour.
