Although most bleeding associated with the use of Angiomax in PCI/PTCA occurs at the site of arterial puncture, hemorrhage can occur at any site. An unexplained fall in blood pressure or hematocrit should lead to serious consideration of a hemorrhagic event and cessation of Angiomax administration [see ADVERSE REACTIONS]. Angiomax should be used with caution in patients with disease states associated with an increased risk of bleeding.
Acute Stent Thrombosis In Patients With STEMI Undergoing PCI
Acute stent thrombosis (AST) (<4 hours) has been observed at a greater frequency in Angiomax treated patients (1.2%, 36/2889) compared to heparin treated patients (0.2%, 6/2911) with STEMI undergoing primary PCI. Among patients who experienced an AST, one fatality (0.03%) occurred in an Angiomax treated patient and one fatality (0.03%) in a heparin treated patient. These patients have been managed by Target Vessel Revascularization (TVR). Patients should remain for at least 24 hours in a facility capable of managing ischemic complications and should be carefully monitored following primary PCI for signs and symptoms consistent with myocardial ischemia.
Coronary Artery Brachytherapy
If a decision is made to use Angiomax during brachytherapy procedures, maintain meticulous catheter technique, with frequent aspiration and flushing, paying special attention to minimizing conditions of stasis within the catheter or vessels [see ADVERSE REACTIONS].
Laboratory Test Interference
Angiomax affects International Normalized Ratio (INR), therefore INR measurements made in patients who have been treated with Angiomax may not be useful for determining the appropriate dose of warfarin.
Carcinogenesis, Mutagenesis, Impairment Of Fertility
No long-term studies in animals have been performed to evaluate the carcinogenic potential of bivalirudin. Bivalirudin displayed no genotoxic potential in the in vitro bacterial cell reverse mutation assay (Ames test), the in vitro Chinese hamster ovary cell forward gene mutation test (CHO/HGPRT), the in vitro human lymphocyte chromosomal aberration assay, the in vitro rat hepatocyte unscheduled DNA synthesis (UDS) assay, and the in vivo rat micronucleus assay. Fertility and general reproductive performance in rats were unaffected by subcutaneous doses of bivalirudin up to 150 mg/kg/day, about 1.6 times the dose on a body surface area basis (mg/m²) of a 50 kg person given the maximum recommended dose of 15 mg/kg/day.
Use In Specific Populations
Pregnancy Category B
Reproductive studies have been performed in rats at subcutaneous doses up to 150 mg/kg/day, (1.6 times the maximum recommended human dose based on body surface area) and rabbits at subcutaneous doses up to 150 mg/kg/day (3.2 times the maximum recommended human dose based on body surface area). These studies revealed no evidence of impaired fertility or harm to the fetus attributable to bivalirudin. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Angiomax is intended for use with aspirin [see INDICATIONS AND USAGE]. Because of possible adverse effects on the neonate and the potential for increased maternal bleeding, particularly during the third trimester, Angiomax and aspirin should be used together during pregnancy only if clearly needed.
It is not known whether bivalirudin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Angiomax is administered to a nursing woman.
The safety and effectiveness of Angiomax in pediatric patients have not been established.
In studies of patients undergoing PCI, 44% were ≥65 years of age and 12% of patients were ≥75 years old. Elderly patients experienced more bleeding events than younger patients. Patients treated with Angiomax experienced fewer bleeding events in each age stratum, compared to heparin.
The disposition of Angiomax was studied in PTCA patients with mild, moderate and severe renal impairment. The clearance of Angiomax was reduced approximately 20% in patients with moderate and severe renal impairment and was reduced approximately 80% in dialysisdependent patients [see CLINICAL PHARMACOLOGY]. The infusion dose of Angiomax may need to be reduced, and anticoagulant status monitored in patients with renal impairment [seeDOSAGE AND ADMINISTRATION].This monograph has been modified to include the generic and brand name in many instances.
