AGGRASTAT

Tirofiban has a half-life of approximately 2 hours. It is cleared from the plasma largely by renal excretion, with about 65% of an administered dose appearing in urine and about 25% in feces, both largely as unchanged tirofiban. Metabolism appears to be limited. Tirofiban is not highly bound to plasma proteins and protein binding is concentration independent over the range of 0.01 to 25 mcg/mL. The unbound fraction in human plasma is 35%. The steady state volume of distribution of tirofiban rang...

Two large-scale clinical studies established the efficacy of AGGRASTAT in the treatment of patients with NSTE-ACS (unstable angina/non-ST elevation MI). The two studies examined AGGRASTAT alone and added to heparin, prior to and after percutaneous coronary revascularization (if indicated) (PRISM-PLUS) and in comparison to heparin in a similar population (PRISM). These trials are discussed in detail below. PRISM-PLUS (Platelet Receptor Inhibition for Ischemic Syndrome Management — Patients Limited by Unstable Signs and Symptoms) In the double-blind PRISM-PLUS trial, 1570 patients with documente...

Bleeding is the most commonly reported adverse reaction. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Medicure at 1-800-509-0544 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trial 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 clinical practice. In the ...

AGGRASTAT is contraindicated in patients with: Severe hypersensitivity reaction to AGGRASTAT (i.e., anaphylactic reactions) [see Adverse Reactions ( 6.2 )] . A history of thrombocytopenia following prior exposure to AGGRASTAT [see Adverse Reactions ( 6.1 )] . Active internal bleeding or a history of bleeding diathesis, major surgical procedure or severe physical trauma within the previous month [s...

AGGRASTAT can cause serious bleeding. If bleeding cannot be controlled discontinue AGGRASTAT. ( 5.1 ) Thrombocytopenia: Discontinue AGGRASTAT and heparin. ( 5.2 ) 5.1 General Risk of Bleeding Bleeding is the most common complication encountered during therapy with AGGRASTAT. Most bleeding associated with AGGRASTAT occurs at the arterial access site for cardiac catheterization. Minimize the use of traumatic or potentially traumatic procedures such as arterial and venous punctures, intramuscular i...

7 DRUG INTERACTIONS Concomitant use of fibrinolytics, anticoagulants and antiplatelet drugs increases the risk of bleeding. Coadministration of fibrinolytics, anticoagulants and antiplatelet agents, increases the risk of bleeding. ( 7 )
