Bottom line
Bivalirudin is a synthetic 20-amino-acid bivalent direct thrombin inhibitor that binds reversibly to both the active site and exosite 1 of thrombin. FDA-approved for PCI with provisional use of GPI and for patients with heparin-induced thrombocytopenia (HIT/HITTS) undergoing PCI. In the EU, the Angiox marketing authorization was withdrawn in 2018 at the MAH's request. Compared with heparin+GPI in the REPLACE-2 trial, bivalirudin+GPI-provisional showed similar ischemic outcomes with less major bleeding.
Identity and composition
| Field | Verified information |
|---|---|
| Preferred name | Bivalirudin |
| Key aliases | Angiomax, Angiox, bivalirudin trifluoroacetate |
| Molecular/sequence identity | 20-amino-acid synthetic linear peptide; sequence: D-Phe-Pro-Arg-Pro-Gly-Gly-Gly-Gly-Asn-Gly-Asp-Phe-Glu-Glu-Ile-Pro-Glu-Glu-Tyr-Leu (amino to carboxy). Approximates the N-terminal fragment of hirudin. |
| Modifications/form | D-Phe at N-terminus; trifluoroacetate salt; Freeze-drying: water is removed by sublimation under reduced pressure, which can improve the stability of peptides and yield a porous dry matrix. Water removal does not sterilize a product, prove its quality, or define how it should later be handled. परिभाषा का स्रोत: Lyophilization, formulation, and stability primer · शब्दावली powder for Administered into a vein. परिभाषा का स्रोत: Neutral gloss; usage context: Routes, devices, and absorption primer · शब्दावली administration after The product-specific pharmaceutical process by which a lyophilized (freeze-dried) solid returns to a liquid dispersion.

Mechanism and pharmacology
Bivalirudin directly and reversibly inhibits thrombin by binding to both the catalytic (active) site and the fibrinogen-binding exosite (anion-binding exosite 1) on circulating and clot-bound thrombin. Unlike heparin, bivalirudin does not require antithrombin III as a cofactor and is not neutralized by platelet factor 4 (no HIT risk).

Dose and administration evidence
Approved labeled regimen
The label summary below is product-, indication-, and jurisdiction-specific; consult the full current label and a licensed clinician/pharmacist.
PCI: 0.75 mg/kg Administered into a vein. परिभाषा का स्रोत: Neutral gloss; usage context: Routes, devices, and absorption primer · शब्दावली bolus, immediately followed by 1.75 mg/kg/h IV infusion for the procedure duration and up to 4 h post-procedure. Continue at 0.2 mg/kg/h for up to 20 h if needed. Reduce infusion to 1.0 mg/kg/h in severe renal impairment (CrCl less than 30 mL/min). Use with aspirin 300-325 mg daily.
Studied regimens (not recommendations)
BAT regimen (1 mg/kg bolus + 2.5/0.2 mg/kg/h infusion) is not the current PCI-recommended dose.
What is not established
ACS patients not undergoing PCI (limitation of use per label).
Coronary artery bypass grafting (studied but not labeled; associated with higher rates of bypass-graft occlusion in some studies).
Pediatric use: not established.
Safety
Established label risks
Bleeding (most common adverse event). Major bleeding 4.0% (Angiomax vs heparin+GPIIb/IIIa) in REPLACE-2; similar to comparator. Intracranial, retroperitoneal, hemoglobin drop >3 g/dL, or transfusion ≥2 units.
Hemorrhage risk increased with concurrent antiplatelet agents, other anticoagulants, thrombolytics.
Allergic reactions: rare; anaphylaxis and hypersensitivity have been reported including urticaria, hypotension, dyspnea.
Thrombocytopenia: reported but incidence similar to comparator. No direct HIT risk (does not interact with platelet factor 4).
Thrombosis (catheter-associated, coronary).
Coronary artery dissection, vessel perforation, pseudoaneurysm.

Human-study signals
Increased ischemic events (death, MI) in patients with STEMI undergoing primary PCI treated with bivalirudin vs heparin in contemporary trials (HEAT-PPCI, MATRIX) — attributable to trial design differences (operator blinding, concurrent antiplatelet use) rather than the drug itself.

Interactions and special populations
Increased bleeding with anticoagulants (heparin, warfarin, GPIs), antiplatelet agents. No CYP metabolism. Renal clearance: reduce dose when CrCl <30 mL/min. Elderly: increased bleeding risk due to age-related renal decline. Geriatric and renally impaired patients should be monitored closely.

Optimal use in ACS patients not undergoing PCI (labeled limitation).
Long-term safety beyond procedural use.
