honestly [70:<50 mL/minute, 180 mcg/kg by IV injection as soon as possible following diagnosis, followed by IV infusion of 1 mcg/kg per minute. 1 Acute Ischemic Complications of PCI In patients with Cl cr> <50 mL/minute, 180 mcg/kg by IV injection immediately before initiation of PCI, followed by IV infusion of 1 mcg/kg per minute and a second IV injection of 180 mcg/kg 10 minutes after the first IV injection. 1 Geriatric Patients No dosage adjustment was made for geriatric patients in clinical trials. 1 (See Geriatric Use under Cautions.) Cautions for Eptifibatide Contraindications History of bleeding diathesis 1 10 13 or active abnormal bleeding within previous 30 days. 1 10 12 13 Severe uncontrolled hypertension (SBP >200 mm Hg or DBP >110 mm Hg with antihypertensive therapy). 1 10 13 Recent (within 6 weeks) major surgery. 1 10 12 13 History of stroke within 30 days or any history of hemorrhagic stroke. 1 10 12 13 Current or planned therapy with another GP IIb/IIIa-receptor inhibitor. 1 Patients undergoing renal dialysis. 1 Known hypersensitivity to eptifibatide or any ingredient in the formulation. 1 Warnings/Precautions Warnings Bleeding Risk of major bleeding (e.g., intracranial hemorrhage, GU or GI bleeding, bleeding at femoral vascular access site) 1 8 17 71 85 117 and minor bleeding (e.g., spontaneous gross hematuria, spontaneous hematemesis); 1 8 17 72 85 may require blood or platelet transfusions. 1 10 117 (See Bleeding Precautions and see Laboratory Monitoring under Cautions.) Patients weighing> <70 kg at increased risk of major bleeding. 1 If bleeding cannot be controlled by pressure, discontinue eptifibatide and concomitant heparin immediately. 1 Use not recommended in patients with hematocrit> <30%. 8 72 Thrombocytopenia Thrombocytopenia reported. 110 111 Severe thrombocytopenia (platelet count> <20,000/mm 3 ) reported less frequently than with abciximab. 8 26 40 55 72 93 99 111 Determine platelet counts prior to treatment and periodically (e.g., daily) 72 during concomitant eptifibatide and heparin therapy. 8 72 88 Consider possibility of heparin-induced thrombocytopenia in patients receiving concomitant heparin therapy. 29 55 93 107 111 If platelet count decreases to> <100,000/mm 3 , discontinue eptifibatide and heparin and initiate appropriate treatment and monitoring. 1 Consider platelet transfusions for management of severe thrombocytopenia. 55 93 106 111 112 No clinical experience with eptifibatide in patients with platelet counts> <100,000/mm 3 . 1 Sensitivity Reactions Hypersensitivity Reactions Anaphylaxis reported. 1 Major Toxicities General Precautions Bleeding Precautions To reduce risk of bleeding, adhere to strict anticoagulation guidelines; use a short course of low-dose, weight-adjusted heparin; avoid vascular and other trauma; carefully manage vascular (e.g., femoral artery) access site; and monitor all potential bleeding sites during and following treatment. 1 26 29 43 52 97 107 109 Manufacturer recommends that concomitant thrombolytic therapy be used with caution. 1 In patients undergoing PCI, use caution in the placement, maintenance, and removal of vascular access sheath. 1 26 44 52 When inserting sheath, puncture only anterior wall of femoral artery; avoid Seldinger (through and through) technique. 8 26 72 Observe appropriate precautions while sheath is in place (e.g., complete bed rest, elevation of head 30 , restrain limb in which sheath is inserted, frequent monitoring of vascular access site and distal pulse in the involved limb). 26 27 72 Following PCI, consider early sheath removal (during eptifibatide IV infusion). 1 Prior to removal of sheath, discontinue heparin for 3 4 hours and allow aPTT to return to> <45 seconds or ACT to> <150 180 seconds. 1 26 27 35 44 Discontinue eptifibatide and heparin and achieve hemostasis (by applying pressure to femoral artery for at least 20 30 minutes after sheath removal 26 27 ) at least 2 4 hours before hospital discharge. 1 Measure and monitor hematomas for enlargement. 8 26 72 To avoid vascular and other trauma, minimize needle punctures (e.g., arterial, IM, IV, lumbar, sub-Q, intradermal), cutdown sites, and use of nasotracheal intubation, nasogastric tubes, urinary catheters, and automatic BP cuffs 26 during and following treatment; 1 8 72 avoid establishment of IV access at noncompressible sites (e.g., subclavian or jugular veins); 1 consider using an indwelling venipuncture device (e.g., heparin lock) for drawing blood; document and monitor vascular puncture sites; and remove dressings gently and carefully. 8 26 72 Laboratory Monitoring Prior to administration, obtain hematocrit or hemoglobin, platelet count, S cr , and PT or aPTT. 1 In patients undergoing PCI, also obtain ACT prior to administration. 1 In patients with unstable angina or non-ST-segment-elevation MI undergoing medical management, target aPTT between 50 70 seconds. 1 In patients undergoing PCI the manufacturer recommends targeting ACT between 200 300 seconds during PCI. 1 Monitor aPTT or ACT prior to arterial sheath removal; do not remove sheath unless aPTT 45 seconds or ACT> <150 180 seconds. 1 26 27 35 44 Specific Populations Pregnancy Category B. 1 Lactation Not known whether eptifibatide is distributed into milk. 1 Use with caution. 1 Pediatric Use Safety and efficacy not established. 1 8 Geriatric Use No substantial differences in efficacy relative to younger adults. 1 However, increased incidence of bleeding complications. 1 Hepatic Impairment Use contraindicated in patients with hepatic disease severe enough to alter synthesis of coagulation factors. 8 Renal Impairment Decreased clearance and increased plasma concentrations in patients with moderate to severe renal impairment (estimated Cl cr> <50 mL/minute); 1 reduced dosage recommended in such patients. 1 (See Renal Impairment under Dosage and Administration.)
