NCIt definition : A 20 amino acid long synthetic peptide with thrombin-specific anticoagulant properties.
Bivalirudin reversibly binds thrombin, free as well as clot bound, at the catalytic
site and the anion-binding exosite, thereby preventing the formation and activation
of fibrin, factor XIIIa, and other coagulation factors. This drug is primarily used
during coronary angioplasty procedures, in combination with aspirin, in patients with
unstable angina.;
Alternative definition : ACC/AHA: Bivalirudin is a semisynthetic derivative of hirudin and is a highly specific
inhibitor of thrombin.;
