General

  • Type: Hemostatics, blood components
  • Dosage Forms:lypophilized concentrate for reconstitution 500u/vial and 1000u/vial
  • Common Trade Names: Kcentra
  • 3 factor PCC (Factors II, IX, and X), would need to supplement with factor VII for reversal if using 3 factor PCC
  • 4 factor PCC (Factors II, VII, IX, and X)

Adult Dosing

  • Based on pretreatment INR, units based on factor 9 content
    • INR 2-4: 25units/kg, not to exceed 2500 units
    • INR 4-6: 35units/kg, not to exceed 3500 units
    • INR >6: 50units/kg, not to exceed 5000 units
  • Consider rechecking INR after 15 minutes to determine need for redosing

Pediatric Dosing

  • Safety and efficacy not established

Special Populations

  • Pregnancy Rating: C
  • Lactation: Unknown, breast feeding not advised
  • Renal Dosing
    • Adult-N/A
    • Pediatric-N/A
  • Hepatic Dosing
    • Adult-N/A
    • Pediatric-N/A

Contraindications

  • Allergy to class/drug
  • DIC
  • known HIT (Heparin induced thrombocytopenia)

Serious

  • Patients receiving PCC for reversal of a vitamin K antagonist (Warfarin) due to life-threatening bleeding have a rate of thromboembolism which is similar to the rate in patients who receive Fresh frozen plasma (7.3% v 7.1%).[1]

Common

Pharmacology

  • Half-life: 4-60 hours, depending on clotting factor
  • Metabolism:
  • Excretion:
  • Mechanism of Action: 4 factor PCC contains factors II, VII, XI, X, protein C and S
