What is it—and why does it matter?
Bivalirudin is described as a 20-residue peptide with thrombin-inhibitory activity. Bivalirudin directly inhibits thrombin. During bivalirudin encounters, thrombotic progression or new thrombosis occurred in 17.6% of encounters, and 18 encounters had both thrombosis and bleeding. As an anticoagulant, bivalirudin for injection is associated with an increased bleeding risk per warning statement.
