Angiomax (bivalirudin) is a reversible direct thrombin inhibitor used to prevent blood clots in people with severe chest pain or other conditions undergoing a procedure called angioplasty (to open blocked arteries). Common side effects of Angiomax include pain in the back or pelvis, nausea, vomiting, stomach pain or upset, restlessness, nervousness, anxiety, headache, fever, sleep problems (insomnia),or pain/bleeding/irritation where the injection was given.

The recommended dose of Angiomax is an intravenous (IV) bolus dose of 0.75 mg/kg, followed by an infusion of 1.75 mg/kg/h for the duration of the PCI/PTCA procedure. Five min. after the bolus dose has been administered, an activated clotting time (ACT) should be performed and an additional bolus of 0.3 mg/kg should be given if needed. Angiomax may interact with blood thinners, or other medications used to prevent blood clots. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant before taking Angiomax. Aspirin is usually given with this drug, and aspirin can cause bleeding when it is taken during the last 3 months of pregnancy. Aspirin can also cause side effects in a newborn. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

(Adverse Reactions)


Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.


In 6010 patients undergoing PCI treated in the REPLACE-2 trial, Angiomax patients exhibited statistically significantly lower rates of bleeding, transfusions, and thrombocytopenia as noted in Table 2.

2Defined as the occurence of any of the following: intracranial bleeding, retroperitoneal bleeding, a transfusion of ≥ 2 units of blood/blood products, a fall in hemoglobin > 4g/dL, whether of not bleeding site is identified, spontaneous or non-spontaneous blood loss with a decrease in hemoglobin > 3g/Dl
3Defined as observed bleeding that does not meet the criteria for major hemorrhage
4TIMI major bleeding is defined as intracranial, or a fall in adjusted Hgb > 5g/dL or Hct of > 15%: TIMI minor bleeding is defined as a fall in adjusted Hgb of 3 to < 5 g/dL or a fall in adjusted Hct of 9 to < 15%, with a bleeding site such as hematuria, hematemesis, hematomas, retroperitoneal bleeding or a decrease in Hgb of > 4 g/dL with no bleeding site
5If < 100,000 and > 25% reduction from baseline, or < 50,000

In 4312 patients undergoing PTCA for treatment of unstable angina in 2 randomized, double-blind studies comparing Angiomax to heparin, Angiomax patients exhibited lower rates of major bleeding and lower requirements for blood transfusions. The incidence of major bleeding is presented in Table 3. The incidence of major bleeding was lower in the Angiomax group than in the heparin group.

-intracranial bleeding 1 ( < 0.1) 2 (0.1)

1No monitoring of ACT (or PTT) was done after a target ACT was achieved.
2Major hemorrhage was defined as the occurence of any of the following, intracranial bleeding, retroperitoneal bleeding, clinically overt bleeding with a decrease in hemoglobin > 3 g/dL or leading to a transfusion of > 2 units of blood. This table includes data from the entire hospitalization period.

In the AT-BAT study, of the 51 patients with HIT/HITTS, 1 patient who did not undergo PCI had major bleeding during CABG on the day following angiography. Nine patients had minor bleeding (mostly due to access site bleeding), and 2 patients developed thrombocytopenia.

Other Adverse Reactions

Adverse reactions, other than bleeding, observed in clinical trials were similar between the Angiomax treated patients and the control groups.

Adverse reactions (related adverse events ) seen in clinical studies in patients undergoing PCI and PTCA are shown in Tables 4 and 5.

Serious, non-bleeding adverse events were experienced in 2% of 2161 Angiomax-treated patients and 2% of 2151 heparin-treated patients. The following individual serious non-bleeding adverse events were rare ( > 0.1% to < 1%) and similar in incidence between Angiomax-and heparin-treated patients. These events are listed by body system: Body as a Whole: fever, infection, sepsis; Cardiovascular: hypotension, syncope, vascular anomaly, ventricular fibrillation; Nervous: cerebral ischemia, confusion, facial paralysis; Respiratory: lung edema; Urogenital: kidney failure, oliguria. In the BAT trial, there was no causality assessment for adverse events.


In in vitro studies, Angiomax exhibited no platelet aggregation response against sera from patients with a history of HIT/HITTS.

Among 494 subjects who received Angiomax in clinical trials and were tested for antibodies, 2 subjects had treatment-emergent positive bivalirudin antibody tests. Neither subject demonstrated clinical evidence of allergic or anaphylactic reactions and repeat testing was not performed. Nine additional patients who had initial positive tests were negative on repeat testing.

Postmarketing Experience

Because postmarketing adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The following adverse reactions have been identified during postapproval use of Angiomax: fatal bleeding; hypersensitivity and allergic reactions including reports of anaphylaxis; lack of anticoagulant effect; thrombus formation during PCI with and without intracoronary brachytherapy, including reports of fatal outcomes.
