Medicure Announces Approval of Expanded Dosing Time For AGGRASTAT®
23 April 2015
WINNIPEG, CANADA – (April 23, 2015) Medicure Inc. ("Medicure" or the "Company") (TSXV:MPH, OTC:MCUJF), a specialty pharmaceutical company, is pleased to announce that the United States Food and Drug Administration (FDA) has approved a revision to the duration of the bolus delivery for the AGGRASTAT® (tirofiban HCl) high-dose bolus (HDB) regimen.
The dosing change and label modification was requested by the Company to help health care professionals more efficiently meet patient-specific administration needs and to optimize the implementation of AGGRASTAT at new hospitals. The newly approved labeling supplement now allows the delivery duration of the AGGRASTAT high-dose bolus (25 mcg/kg) to occur anytime within 5 minutes, instead of the previously specified duration of 3 minutes. This change is part of Medicure’s ongoing regulatory strategy to expand the applications for AGGRASTAT.
"We believe the revised dosing time window will offer health care professionals greater flexibility in the administration of AGGRASTAT, allowing the duration of the bolus dose to be tailored to the needs of the patient," stated Dawson Reimer, President and Chief Operating Officer, Medicure Inc. "As AGGRASTAT utilization continues to expand across the United States, the label modification is part of our strategy to best position our product in the evolving field of interventional cardiology."
The AGGRASTAT HDB regimen was originally approved by the FDA in October 2013 as a part of the Company’s supplemental New Drug Application (sNDA). The total bolus dose (25 mcg/kg), maintenance infusion (0.15 mcg/kg/min) and indication for AGGRASTAT have not been modified as a part of the labeling supplement. With the FDA approval letter announced today, the infusion duration for delivery of the bolus in the AGGRASTAT prescribing information has been changed from "over 3 minutes" to "within 5 minutes".

Indications and Usage
AGGRASTAT is indicated to reduce the rate of thrombotic cardiovascular events (combined endpoint of death, myocardial infarction, or refractory ischemia/repeat cardiac procedure) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS).
Dosage and Administration
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.
Warnings and Precautions
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 arterial and venous punctures, intramuscular injections, nasotracheal intubation, etc. Fatal bleeding events have been reported. Concomitant use of fibrinolytics, oral anticoagulants and antiplatelet drugs increases the risk of bleeding.
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/mm3, 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.
