Mechanism of Action: Bivalirudin is a synthetic 20-amino acid analogue of the naturally occurring hirudin. It is a specific and reversible direct thrombin inhibitor thats works by binding to the catalytic and anionic exosite of circulating and clot-bound thrombin. It is used as an anticoagulant in percutaneous coronary intervention.
Distribution: Does not bind to plasma proteins. Volume of distribution: 200 mL/kg.
Metabolism: Partly metabolised by the kidneys.
Excretion: Via urine (approx 20%) and proteolytic cleavage. Elimination half-life (normal renal function): Approx 25 min.
Unopened vial: Store between 15-30°C. Reconstituted soln: Store between 2-8°C for up to 24 hr.
