CAS 128270-60-0
Bivalirudin is 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.

4.2 Drug Indication

For treatment of heparin-induced thrombocytopenia and for the prevention of thrombosis. Bivalirudin is indicated for use in patients undergoing percutaneous coronary intervention (PCI), in patients at moderate to high risk acute coronary syndromes due to unstable angina or non-ST segment elevation in whom a PCI is planned.


FDA Label


Angiox is indicated as an anticoagulant in adult patients undergoing percutaneous coronary intervention (PCI), including patients with ST-segment-elevation myocardial infarction (STEMI) undergoing primary PCI.

Angiox is also indicated for the treatment of adult patients with unstable angina / non-ST-segment-elevation myocardial infarction (UA / NSTEMI) planned for urgent or early intervention.

Angiox should be administered with aspirin and clopidogrel.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Bivalirudin mediates an inhibitory action on thrombin by directly and specifically binding to both the catalytic site and anion-binding exosite of circulating and clot-bound thrombin. The action of bivalirudin is reversible because thrombin will slowly cleave the thrombin-bivalirudin bond which recovers the active site of thrombin.


5.2 MeSH Pharmacological Classification

Antithrombins

Endogenous factors and drugs that directly inhibit the action of THROMBIN, usually by blocking its enzymatic activity. They are distinguished from INDIRECT THROMBIN INHIBITORS, such as HEPARIN, which act by enhancing the inhibitory effects of antithrombins. (See all compounds classified as Antithrombins.)

5.5 Absorption, Distribution and Excretion

Absorption

Following intravenous administration, bivalirudin exhibits linear pharmacokinetics. The mean steady state concentration is 12.3 +/- 1.7mcg/mL after administration of an intravenous bolus of 1mg/kg followd by a 2.5mg/kg/hr intravenous infusion given over 4 hours.


Route of Elimination

Bivalirudin is cleared from plasma by a combination of renal mechanisms (20%) and proteolytic cleavage.


Volume of Distribution

Clearance

3.4 mL/min/kg [Normal renal function]

3.4 mL/min/kg [mild renal function]

1 mL/min/kg [Dialysis-dependent patients]


5.6 Metabolism/Metabolites

80% proteolytic cleavage


5.7 Biological Half-Life

Normal renal function: 25 min (in normal conditions)

Creatinine clearance 10-29mL/min: 57min

Dialysis-dependant patients: 3.5h


5.8 Mechanism of Action

Inhibits the action of thrombin by binding both to its catalytic site and to its anion-binding exosite. Thrombin is a serine proteinase 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.
