Kengreal is supplied as asterile white to off-white lyophilized powder for reconstitution into an IV infusion. The recommended dosage is a 30 mcg/kg IV bolus followed immediately by a 4 mcg/kg/min IV infusion. Initiate the bolus infusion prior to PCI. The maintenance infusion should ordinarily be continued for at least 2 hours or for the duration of PCI, whichever is longer.
