Pronunciation
ep-ti-FIB-a-tide [Pronunciation]
Trade Name(s)
Integrilin
Pregnancy CategoryCategory BTher. class.antiplatelet agentsPharm. class.glycoprotein iib iiia inhibitors
Indications
Acute coronary syndrome (unstable angina/nonQ-wave MI), including patients who will be managed medically and those who will undergo percutaneous coronary intervention (PCI) that may consist of percutaneous transluminal angioplasty (PCTA) or atherectomy.
Treatment of patients undergoing PCI.
Usually used concurrently with aspirin and heparin.
Action
Decreases platelet aggregation by reversibly antagonizing the binding of fibrinogen to the glycoprotein IIb/IIIa binding site on platelet surfaces.
Therapeutic Effect(s):
Inhibition of platelet aggregation resulting in decreased incidence of new MI, death, or refractory ischemia, reducing the need for repeat urgent cardiac intervention.
Pharmacokinetics
Absorption: IV administration results in complete bioavailability.
Distribution: Unknown.
Metabolism and Excretion: 50% excreted by the kidneys.
Half-life: 2.5 hr.

Inhibition is reversible following cessation of infusion
Contraindication/Precautions
Contraindicated in:
Hypersensitivity;
Active internal bleeding or history of bleeding within previous 30 days;
Severe uncontrolled hypertension (systolic BP >200 mm Hg and/or diastolic BP >110 mm Hg);
Major surgical procedure within 6 wk;
History of hemorrhagic stroke or other stroke within 30 days;
Concurrent use of other glycoprotein IIb/IIIa receptor antagonists;

Interactions
Drug-Drug
↑ risk of bleeding with other drugs that affect hemostasis ( heparins , warfarin , NSAIDs , thrombolytic agents , abciximab , dipyridamole , ticlopidine , clopidogrel , some cephalosporins , valproates ).
Drug-Natural Products
↑ bleeding risk with arnica , chamomile , clove , dong quai , feverfew , garlic , ginger , ginkgo , and Panax ginseng .
Route/Dosage
Acute Coronary Syndrome
IV (Adults ≤121 kg): 180 mcg/kg as a bolus dose, followed by 2 mcg/kg/min until hospital discharge or surgical intervention (up to 72 hr)..
Percutaneous Coronary Intervention IV (Adults): 180 mcg/kg as a bolus dose, immediately before PCI, followed by 2 mcg/kg/min infusion; a second bolus of 180 mcg/kg is given 10 min after first bolus; infusion should continue for 1824 or hospital discharge (minimum of 12 hr)..
Renal Impairment (Adults CCr <50 mL/min): 180 mcg/kg bolus followed by 1 mcg/kg/min infusion; second bolus of 180 mcg/kg is given 10 min after first bolus for patients undergoing PCI..
Availability
Solution for injection: 20 mg/10 mL, 75 mg/100 mL, 200 mg/100 mL
Assessment
Assess for bleeding. Most common sites are arterial access site for cardiac catheterization or GI or GU tract. Arterial and venous punctures, IM injections, and use of urinary catheters, nasotracheal intubation, and NG tubes should be minimized. Noncompressible sites for IV access should be avoided. If bleeding cannot be controlled with pressure, discontinue eptifibatide and heparin immediately.
Lab Test Considerations
Prior to eptifibatide therapy, assess hemoglobin or hematocrit, platelet count, serum creatinine, and PT/aPTT. Activated clotting time (ACT) should also be measured in patients undergoing PCI.
» Maintain the aPTT between 50 and 70 sec unless PCI is to be performed. Maintain ACT between 300 and 350 sec during PCI.
» Arterial sheath should not be removed unless aPTT <45 sec.
» If platelet count decreases to <100,000 and is confirmed, eptifibatide and heparin should be discontinued and condition monitored and treated.
Potential Nursing Diagnoses
Ineffective tissue perfusion (Indications)
Implementation
High Alert: Accidental overdose of antiplatelet medications has resulted in patient harm or death from internal hemorrhage or intracranial bleeding. Have second practitioner independently check original order, dose calculations, and infusion pump settings.
Most patients receive heparin and aspirin concurrently with eptifibatide.
» After PCI, femoral artery sheath may be removed during eptifibatide treatment only after heparin has been discontinued and its effects mostly reversed.
» Do not administer solutions that are discolored or contain particulate matter. Discard unused portion.
IV Adminstration: pH:
5.0.
Direct IV:
High Alert: Diluent: Withdraw appropriate loading dose from bolus vial (20 mg/10-mL vial) into a syringe. Administer undiluted
