What is Aggrastat?

From the FDA label:AGGRASTAT contains tirofiban hydrochloride, a non-peptide antagonist of the platelet GP IIb/IIIa receptor, which inhibits platelet aggregation. Tirofiban hydrochloride monohydrate is chemically described as N- (butylsulfonyl)- O -[4-(4-piperidinyl)butyl]-L-tyrosine monohydrochloride monohydrate. Its molecular formula is C 22 H 36 N 2 O 5 S•HCl•H 2 O and its structural formula is: Tirofiban hydrochloride monohydrate is a white to off-white, non-hygroscopic, free-flowing powder, with a molecular weight of 495.08. It is very slightly soluble in water. AGGRASTAT Injection Premixed is supplied as a sterile solution in water for injection, for intravenous use. The pH of the solution ranges from 5.5 to 6.5 adjusted with hydrochloric acid and/or sodium hydroxide. Each 100 mL of the premixed, isosmotic intravenous injection contains 5.618 mg tirofiban hydrochloride monohydrate equivalent to 5 mg tirofiban (50 mcg/mL) and the following inactive ingredients: 0.9 g sodium chloride, 54 mg sodium citrate dihydrate, and 3.2 mg citric acid anhydrous. Each 250 mL of the premixed, isosmotic intravenous injection contains 14.045 mg tirofiban hydrochloride monohydrate equivalent to 12.5 mg tirofiban (50 mcg/mL) and the following inactive ingredients: 2.25 g sodium chloride, 135 mg sodium citrate dihydrate, and 8 mg citric acid anhydrous. AGGRASTAT Injection Premixed Bolus Vial is supplied as a…

How to use

Administer intravenously 25 mcg/kg within 5 minutes and then 0.15 mcg/kg/min for up to 18 hours. In patients with creatinine clearance ≤60 mL/min, give 25 mcg/kg within 5 minutes and then 0.075 mcg/kg/min. ( 2 ) 2.1 Recommended Dosage The recommended dosage is 25 mcg/kg administered intravenously within 5 minutes and then 0.15 mcg/kg/min for up to 18 hours. 2.2 Administration For intravenous use only. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. To open the 100 mL or 250 mL premixed bag, first tear off its foil overpouch. The plastic may be somewhat opaque because of moisture absorption during sterilization; the opacity will diminish gradually. Check for leaks by squeezing the inner bag firmly; if any leaks are found or sterility is suspect then the solution should be discarded. Do not use unless the solution is clear and the seal is intact. Administration Instructions Withdraw the bolus dose of AGGRASTAT from the 15 mL premixed bolus vial into a syringe. Alternatively, the bolus dose of AGGRASTAT may be administered from the 100 mL or 250 mL premixed bag. Do not dilute. Administer the bolus dose within 5 minutes via a syringe or IV pump. For patients ≥ 167 kg, it is recommended that the bolus dose be administered via syringe from the 15 mL premixed bolus vial, to…

Side effects

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 PRISM (Platelet Receptor Inhibition for Ischemic Syndrome Management), PRISM-PLUS (Platelet Receptor Inhibition for Ischemic Syndrome Management — Patients Limited by Unstable Signs and Symptoms) and RESTORE (Randomized Efficacy Study of Tirofiban for Outcomes and Restenosis) trials, 1946 patients received AGGRASTAT in combination with heparin and 2002 patients received AGGRASTAT alone for about 3 days. Forty-three percent of the population was >65 years of age and approximately 30% of patients were female. In clinical studies with the recommended regimen (25 mcg/kg bolus followed by a 0.15 mcg/kg/min maintenance infusion), AGGRASTAT was administered in combination with aspirin, clopidogrel and heparin or bivalirudin to over 8000 patients for typically ≤24 hours. Approximately 30% of the population was >65 years of age and approximately 25% were female. Bleeding PRISM-PLUS Regimen The…

Warnings

Important safety information

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 injections, nasotracheal intubation, etc. Concomitant use of fibrinolytics, anticoagulants and antiplatelet drugs increases the risk of bleeding. 5.2 Thrombocytopenia Profound thrombocytopenia has been reported with AGGRASTAT. Monitor platelet counts beginning about 6 hours after treatment initiation and daily thereafter. If the platelet count decreases to <90,000/mm 3 , monitor platelet counts to exclude pseudothrombocytopenia. If thrombocytopenia is confirmed, discontinue AGGRASTAT and heparin. Previous exposure to a glycoprotein (GP) IIb/IIIa receptor antagonist may increase the risk of developing thrombocytopenia [see Adverse Reactions ( 6.1 )] .

Who should not take Aggrastat

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 [see Adverse Reactions ( 6.1 ) ]. Known hypersensitivity to any component of AGGRASTAT. ( 4 ) History of thrombocytopenia with prior exposure to AGGRASTAT. ( 4 ) Active internal bleeding, or history of bleeding diathesis, major surgical procedure or severe physical trauma within the previous month. ( 4 )

Overdose — what happens if you take too much

In clinical trials, inadvertent overdosage with AGGRASTAT occurred in doses up to 2 times the recommended dose for initial infusion doses. Inadvertent overdosage occurred in doses up to 9.8 times the 0.15 mcg/kg/min maintenance infusion rate. The most frequently reported manifestation of overdosage was bleeding, primarily minor mucocutaneous bleeding events and minor bleeding at the sites of cardiac catheterization [see Warnings and Precautions ( 5.1 )]. Overdosage of AGGRASTAT should be treated by assessment of the patient’s clinical condition and cessation or adjustment of the drug infusion as appropriate. AGGRASTAT can be removed by hemodialysis.

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 )
