Is Argatroban bivalirudin?
Is Argatroban bivalirudin?
Background: Argatroban and bivalirudin are direct thrombin inhibitors (DTIs) used for the treatment of heparin-induced thrombocytopenia (HIT). The purpose of this study was to determine whether either agent offered an advantage in efficacy and ability to remain within the targeted therapeutic anticoagulation range.
Is bivalirudin approved for HIT?
Bivalirudin is the most recent direct thrombin inhibitor to be introduced to the market, but it is not currently FDA approved for HIT.
What drug class is bivalirudin?
Bivalirudin is a medication used to manage and treat patients undergoing percutaneous coronary intervention for acute myocardial infarction. It is in the direct thrombin inhibitor class of drugs.
When do you use bivalirudin?
Bivalirudin (Angiomax) is a specific and reversible direct thrombin inhibitor, used for anticoagulant in patients with unstable angina undergoing percutaneous transluminal coronary angioplasty, patients undergoing PCI, or in patients with, or at risk of heparin-induced thrombocytopenia (HIT), undergoing PCI[2].
Can bivalirudin cause thrombocytopenia?
The incidence of major bleeding was lower in the bivalirudin group than in the heparin group….Bleeding.
| Bivalirudin with “provisional” GPI1 (n=2,914) | Heparin + GPI (n=2,987) | |
|---|---|---|
| Access site bleeding | ||
| – Sheath site bleeding | 0.9% | 2.4% |
| Thrombocytopenia5 | ||
| <100,000 | 0.7% | 1.7% |
Does bivalirudin affect platelets?
Conclusions—Bivalirudin effectively suppresses thrombin-dependent platelet activation via inhibition of PAR1 cleavage and inhibits collagen-induced platelet procoagulant activity as well as systemic thrombin levels in patients undergoing PCI.

What is the brand name for bivalirudin?
Bivalirudin (Bivalitroban), sold under the brand names Angiomax and Angiox and manufactured by The Medicines Company, is a direct thrombin inhibitor (DTI). Chemically, it is a synthetic congener of the naturally occurring drug hirudin, found in the saliva of the medicinal leech Hirudo medicinalis.
Is bivalirudin a low molecular weight heparin?
Fondaparinux is essentially a synthetic, short molecule shaped like heparin. It exerts no activity against factor IIa, working purely via inhibition of Xa. All of these agents are effective only against fluid-phase clotting factors.
How do you reverse thrombocytopenia?
If your platelet level becomes too low, your doctor can replace lost blood with transfusions of packed red blood cells or platelets. Medications. If your condition is related to an immune system problem, your doctor might prescribe drugs to boost your platelet count. The first-choice drug might be a corticosteroid.
Does bivalirudin inhibit platelet function?
Conclusions: Bivalirudin effectively suppresses thrombin-dependent platelet activation via inhibition of PAR1 cleavage and inhibits collagen-induced platelet procoagulant activity as well as systemic thrombin levels in patients undergoing PCI.
Which is better argatroban or bivalirudin for clot stabilization?
In contrast to heparins that require antithrombin to inhibit thrombin, argatroban and bivalirudin are DTIs that bind to thrombin independent of antithrombin, as shown in figure 1. DTIs, unlike UFH, inhibit both plasma and fibrin bound thrombin. 3 Fibrin bound thrombin activates platelets in the forming thrombus for clot stabilization.
When to use argatroban for thrombosis treatment?
Current labeling for argatroban is for prophylaxis or treatment of thrombosis in patients with HIT, and as an anticoagulant in adult patients with or at risk for HIT undergoing PCI ( https://www.accessdata.fda.gov/drugsatfda_docs/label/2011/022485lbl.pdf; accessed November 28, 2017).
When to use argatroban and bivalirudin in ICU?
In this review, we summarize clinical data of argatroban and bivalirudin and evaluate their potential use in the setting of cardiovascular surgery as well as in the intensive care unit (ICU).
How is bivalirudin cleaved by thrombin in proteolysis?
Bivalirudin is cleaved by thrombin via proteolysis. This represents the major elimination mechanism of bivalirudin. Modified from Lee CJ, Ansell JE: Direct thrombin inhibitors. Br J Clin Pharmacol 2011; 72:581–92.
