Prototype: Abciximab
Pregnancy Category: B


0.75 mg/mL, 2 mg/mL injection


Binds to the glycoprotein IIb/IIIa (GPIIb/IIIa) receptor sites of platelets.

Therapeutic Effect

Inhibits platelet aggregation by preventing fibrinogen, von Willebrand's factor, and other molecules from adhering to GPIIb/IIIa receptor sites on platelets.


Treatment of acute coronary syndromes (unstable angina, non-Q-wave MI) and patients undergoing percutaneous coronary interventions (PCIs).


Hypersensitivity to eptifibatide; active bleeding; GI or GU bleeding within 6 wk; thrombocytopenia; renal failure requiring dialysis; coagulopathy; recent major surgery or trauma; intracranial neoplasm, intracranial bleeding within 6 mo; concurrent administration of another GPIIb/IIIa receptor inhibitor (e.g., abciximab); severe hypertension (systolic blood pressure >200 mm Hg or diastolic blood pressure >110 mm Hg), aneurysm.

Cautious Use

Hypersensitivity to related compounds (e.g., abciximab, tirofiban, lamifiban); concurrent administration of other anticoagulants; pregnancy (category B), lactation. Safety and effectiveness in children are not established.

Route & Dosage

Acute Coronary Syndromes (ACS)
Adult: IV 180 mcg/kg initial bolus (max: 22.6 mg) followed by 2 mcg/kg/min until hospital discharge or up to 72 h

Percutaneous Coronary Interventions (PCI)
Adult: IV 180 mcg/kg initial bolus followed by 2 mcg/kg/min; after 10 min, a second 180 mcg/kg bolus should be given; the infusion should continue up to 24 h after the end of the procedure

Renal Impairment
If Clcr 10–49 mL/min, then give 1 mcg/kg/min continuous infusion.


  • Note: Review contraindications to administration prior to giving this drug.

PREPARE: Direct: Give undiluted.  

ADMINISTER: Direct: Give bolus doses IV push over 1–2.  Continuous: Start continuous infusion immediately following bolus dose. Give undiluted directly from the 100-mL vial (at a rate based on patient's weight) using a vented infusion set. May be given in the same IV line with NS or D5/NS (either solution may contain up to 60 mEq KCl).  

  • Store unopened vials at 2°–8° C (36°–46° F) and protect from light. Discard any unused portion in opened vial.

Adverse Effects (≥1%)

CNS: Intracranial bleed (rare). GI: GI bleeding. Hematologic: Bleeding (major bleeding 4.4–11%), anemia, thrombocytopenia.


Drug: oral anticoagulants, nsaids, dipyridamole, ticlopidine, dextran may increase risk of bleeding.


Duration: 6–8 h after stopping infusion. Metabolism: Minimally metabolized. Elimination: 50% in urine. Half-Life: 2.5 h.

Nursing Implications

Assessment & Drug Effects

  • Lab tests: Prior to infusion determine PT/aPTT & INR, ACT for those undergoing percutaneous coronary intervention (PCI); Hct or Hgb; platelet count; and serum creatinine.
  • Lab tests: Monitor aPTT & INR (target aPPT, 50–70 s); during PCI (target ACT, 300–350 s).
  • Minimize all vascular and other trauma during treatment. When obtaining IV access, avoid using a noncompressible site such as the subclavian vein.
  • Monitor carefully for and immediately report S&S of bleeding (e.g., femoral artery access site bleeding, intracerebral hemorrhage, GI bleeding).
  • Immediately stop infusion of eptifibatide and heparin if bleeding at the arterial access site cannot be controlled by pressure.
  • Achieve hemostasis at the arterial access site by standard compression for a minimum of 4 h prior to hospital discharge following discontinuation of eptifibatide and heparin.
