Contents of the pack and other information
Kengrexal is an anti-platelet medicine that contains the active substance cangrelor.
Platelets are very small cells in the blood that can clump together and help the blood to clot. Sometimes clots can form within a damaged blood vessel such as in an artery in the heart and this can be very dangerous as the clot can cut off the blood supply (a thrombotic event), causing a heart attack (myocardial infarction).
Kengrexal diminishes the clumping of platelets and so reduces the chance of a blood clot forming.
You have been prescribed Kengrexal because you have blocked blood vessels in your heart (coronary artery disease) and you need a procedure (called a percutaneous coronary intervention – PCI) to remove the blockage. During this procedure you may have a stent inserted in your blood vessel to help to keep it open. Using Kengrexal reduces the risk that this procedure will cause a clot to form and block the blood vessels again.
Kengrexal is only for use in adults.
If you are allergic to cangrelor or any of the other ingredients of this medicine (listed in section 6).
If you have a medical condition that is currently causing bleeding such as bleeding from the stomach or intestines or you have a condition which makes you more prone to uncontrolled bleeding (impaired haemostasis or irreversible coagulation disorders).
If you have recently undergone major surgery or suffered from any form of serious physical trauma such as a bone fracture or road traffic accident.
If you have uncontrolled very high blood pressure.
If you have ever had a stroke, or a ‘mini-stroke’ (also known as a transient ischaemic attack, TIA) caused by the temporary interruption of the blood supply to the brain.
Talk to your doctor before using Kengrexal if:
You are, or you think you may be at increased risk of bleeding. For example, if you have a medical condition that affects blood clotting or because of another medical condition that may increase the risk of bleeding such as a recent serious injury, any recent surgery, history of a stroke or a transient ischaemic attack or recent bleeding from your stomach or gut.
You suffer from impaired kidney function or require dialysis.
You have ever suffered from an allergic reaction to Kengrexal or any of its constituents.
You suffer from breathing difficulties such as asthma.
You have been told by your doctor that you have an intolerance to some sugars.
Kengrexal is not recommended for children and adolescents under 18 years.
You may receive acetylsalicylic acid (ASA) while you are treated with Kengrexal or another type of anti-platelet medicine (e.g., clopidogrel) before and after you are treated with Kengrexal.
Tell your doctor if you are taking other medicines that may increase the risk of side effects such as bleeding including blood thinners (anticoagulants e.g. warfarin).
Tell your doctor if you are taking, have recently taken or might take any other medicines.
If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine. Kengrexal is not recommended for use during pregnancy.
The effect of Kengrexal wears off quickly and it is unlikely to affect your ability to drive or to use machines.
Sorbitol is a source of fructose. If you have hereditary fructose intolerance (HFI), a rare genetic disorder, you must not receive this medicine. Patients with HFI cannot break down fructose, which may cause serious side effects.
You must tell your doctor before receiving this medicine if you have HFI.
This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially ‘sodium- free’.
Your treatment with Kengrexal will be supervised by a doctor experienced in caring for patients with heart disease. The doctor will decide how much Kengrexal you receive, and will prepare the medicine.
Kengrexal is for injection, followed by infusion (drip), into a vein. The dose given depends on your weight.
The recommended dose is:
30 micrograms per kilogram body weight by injection, followed immediately by
4 micrograms per kilogram body weight per minute by infusion (drip), for at least 2 hours. The doctor will decide if you will need to be treated for longer periods.
This medicine will be given to you by a healthcare professional. Your doctor will decide how to treat you, including stopping the medicine and monitoring for signs of side effects.
If you have any further questions on the use of this medicine, ask your doctor.

------------------------------------------------------------------------------------------------------------
Kengrexal should be administered by a physician experienced in either acute coronary care or in coronary intervention procedures and is intended for specialised use in an acute and hospital setting.
Posology
The recommended dose of Kengrexal for patients undergoing PCI is a 30 micrograms/kg intravenous bolus followed immediately by 4 micrograms/kg/min intravenous infusion. The bolus and infusion should be initiated prior to the procedure and continued for at least two hours or for the duration of the procedure, whichever is longer. At the discretion of the physician, the infusion may be continued for a total duration of four hours, see section 5.1.
Patients should be transitioned to oral P2Y12 therapy for chronic treatment. For transition, a loading dose of oral P2Y12 therapy (clopidogrel, ticagrelor or prasugrel) should be administered immediately following discontinuation of cangrelor infusion. Alternatively, a loading dose of ticagrelor or prasugrel, but not clopidogrel, may be administered up to 30 minutes before the end of the infusion, see section 4.5.
Instructions for preparation
Aseptic procedures should be used for the preparation of Kengrexal.
The vial should be reconsituted immediately prior to dilution and use. Reconstitute each 50 mg/vial by adding 5 mL of sterile water for injection. Swirl gently until all material is dissolved. Avoid vigorous mixing. Allow any foam to settle. Ensure that the contents of the vial are fully dissolved and the reconstituted material is a clear, colourless to pale yellow solution.
Do not use without dilution. Before administration, 5 mL reconstituted solution has to be withdrawn from each vial and must be diluted further with 250 mL sodium chloride 9 mg/mL (0.9%) solution for injection or glucose (5%) solution for injection. Mix the bag thoroughly.
The medicinal product should be inspected visually for particulate matter after reconstitution.
Kengrexal is administered as a weight-based regimen consisting of an initial intravenous bolus followed by an intravenous infusion. The bolus and infusion should be administered from the infusion solution.
This dilution will generate a concentration of 200 micrograms/mL and should be sufficient for at least two hours of dosing as required. Patients 100 kg and over will require a minimum of two bags.
