Bivalirudin

BIVALIRUDIN- bivalirudin injection, powder, lyophilized, for solution
Athenex Pharmaceutical Division, LLC.

1 INDICATIONS AND USAGE

Bivalirudin for Injection is indicated for use as an anticoagulant for use in patients undergoing percutaneous coronary intervention (PCI) including patients with heparin-induced thrombocytopenia and heparin-induced thrombocytopenia and thrombosis syndrome.

2 DOSAGE AND ADMINISTRATION

2.1 Recommended Dosage

Bivalirudin for injection has been studied only in patients receiving concomitant aspirin.

The recommended dose of bivalirudin for injection is an intravenous bolus dose of 0.75 mg/kg, followed immediately by an infusion of 1.75 mg/kg/h for the duration of the procedure. Five minutes after the bolus dose has been administered, an activated clotting time (ACT) should be performed and an additional bolus of 0.3 mg/kg should be given if needed.

Extended duration of infusion following PCI at 1.75 mg/kg/h for up to 4 hours post-procedure should be considered in patients with ST segment elevation MI (STEMI).

2.2 Dose Adjustment in Renal Impairment

Bolus Dose

No reduction in the bolus dose is needed for any degree of renal impairment.

Maintenance Infusion

In patients with creatinine clearance less than 30 mL/min (by Cockcroft Gault equation), reduce the infusion rate to 1 mg/kg/h. Monitor anticoagulant status in patients with renal impairment.

In patients on hemodialysis, reduce the infusion rate to 0.25 mg/kg/h [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].

2.3 Instructions for Preparation and Administration

Bivalirudin for injection is intended for intravenous bolus injection and continuous infusion after reconstitution and dilution.

Preparation Instructions for Bolus Injection and Continuous Infusion

  • To each 250 mg vial, add 5 mL of Sterile Water for Injection, USP.
  • Gently swirl until all material is dissolved.
  • Withdraw and discard 5 mL from a 50 mL infusion bag containing 5% Dextrose in Water or 0.9% Sodium Chloride for Injection.
  • Add the contents of the reconstituted vial to the infusion bag containing 5% Dextrose in Water or 0.9% Sodium Chloride for Injection to yield a final concentration of 5 mg/mL (e.g., 1 vial in 50 mL; 2 vials in 100 mL; 5 vials in 250 mL).
  • Adjust the dose to be administered according to the patient’s weight (see Table 1).
