Lepirudin is a potent, direct thrombin inhibitor used for anticoagulation in patients with heparin-induced thrombocytopenia type II (HIT). The half-life of lepirudin is prolonged in patients with renal insufficiency. Preliminary studies suggest that it is safe to use lepirudin in patients being treated with intermittent hemodialysis but information regarding its use with continuous renal replacement therapy (CRRT) is scarce. CRRT is used in acute care settings to remove fluid and uremic toxins in patients with renal failure with hemodynamic instability. Patients with HIT, renal failure, and hemodynamic instability pose a complex situation for clinical management. These patients require anticoagulation with nonheparin agents with simultaneous CRRT. There are no guidelines in the literature regarding the management of this patient group. We report our experience with lepirudin at managing four such patients with HIT, being treated with CRRT.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
