Chemically it constitutes a synthetic congener of the naturally occurring drug hirudin (found in the saliva of the medicinal leech Hirudo medicinalis ).

Both bivalirudin and hirudin directly inhibit thrombin by specifically binding as well to the catalytic site and to the anion-binding exosite of circulating and clot- or thrombus-bound thrombin. Thrombin is a serine protease that plays a central role in the thrombotic process, acting to cleave fibrinogen into fibrin monomers and to activate Factor XIII to Factor XIIIa, allowing fibrin to develop a covalently cross-linked framework which stabilizes the thrombus; thrombin also activates Factors V and VIII, promoting further thrombin generation, and activates platelets, stimulating aggregation and granule release. less
