What is cangrelor, and how does it work (mechanism of action)?
- Cangrelor is an anti-platelet drug, that is, a drug
that inhibits the ability of platelets to clump together as part of a blood
clot. Cangrelor prevents
blood clots by
reversibly binding to the P2Y12 receptor on platelets, preventing
adenosine
diphosphate (ADP) from activating platelets. It belongs to a class of
drugs
called P2Y12 inhibitors. Other drugs in this class include
- clopidogrel (Plavix),
- ticagrelor (Brilinta), and
- prasugrel (Effient).
- Cangrelor is different from other P2Y12 inhibitors because it prevents clotting faster and its effect does not last as long after it is stopped. After administration, platelet inhibition begins within 2 minutes, lasts for the duration of the infusion, and platelet function returns to normal within 1 hour after stopping the infusion.
What brand names are available for cangrelor?
Kengreal
Is cangrelor available as a generic drug?
No
Do I need a prescription for cangrelor?
Yes
What are the uses for cangrelor?
- Cangrelor is used during percutaneous coronary intervention (PCI) for reducing the risk of heart attacks, repeat coronary revascularization, and stent thrombosis (ST) in patients who have not been treated with another P2Y12 platelet inhibitor and are not receiving a glycoprotein IIb/IIIa inhibitor, another class of platelet inhibitors.
What are the side effects of cangrelor?
The most common adverse effect of cangrelor are:
- Bleeding
- Shortness of breath
Other side effects include:
- Increased risk of kidney impairment
Possible serious side effects include:
- Allergic reactions
- Severe bleeding
- Anaphylaxis

QUESTION
In the U.S., 1 in every 4 deaths is caused by heart disease. See AnswerWhat is the dosage for cangrelor?
- Cangrelor is administered by intravenous (IV) infusion. The recommended dose is a 30 mcg/kg IV bolus before PCI followed immediately by a 4 mcg/kg/min IV maintenance infusion.
- The maintenance infusion should be continued for at least 2 hours or for the duration of PCI, whichever is longer.
Which drugs or supplements interact with cangrelor?
- If clopidogrel or prasugrel are given during cangrelor infusion, they will have no antiplatelet effect until the next dose is given. Therefore clopidogrel and prasugrel should not be given until the cangrelor infusion is stopped.
Is cangrelor safe to take if I'm pregnant or breastfeeding?
- Use of cangrelor in pregnant females has not been adequately studied.
- It is not known whether cangrelor is excreted in human milk.
What else should I know about cangrelor?
What preparations of cangrelor are available?
Powder for injection: 50 mg vial (10 ml)
How should I keep cangrelor stored?
Vials should be stored at room temperature, between 20 C - 25 C (68 F - 77 F).

Heart Attack Symptoms and Early Warning Signs
Recognizing heart attack symptoms and signs can help save your life or that of someone you love. Some heart attack symptoms, including left arm pain and chest pain, are well known but other, more nonspecific symptoms may be associated with a heart attack. Nausea, vomiting, malaise, indigestion, sweating, shortness of breath, and fatigue may signal a heart attack. Heart attack symptoms and signs in women may differ from those in men.

How the Heart Works
The heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.

Heart Disease
Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include: Smoking High blood pressure High cholesterol Diabetes Family history Obesity Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.

Heart Disease in Women
Heart disease in women has somewhat different symptoms, risk factors, and treatment compared to heart disease in men. Many women and health professionals are not aware of the risk factors for heart disease in women and may delay diagnosis and treatment. Lifestyle factors such as diet, exercise, tobacco use, overweight/obesity, stress, alcohol consumption, and depression influence heart disease risk in women. High blood pressure, high cholesterol, and diabetes also increase women's risk of heart disease. Electrocardiogram (EKG or ECG), stress-ECG, endothelial testing, ankle-brachial index (ABI), echocardiogram, nuclear imaging, electron beam CT, and lab tests to assess blood lipids and biomarkers of inflammation are used to diagnose heart disease. Early diagnosis and treatment of heart disease in women saves lives. Heart disease can be prevented and reversed with lifestyle changes.

Heart disease treatment in women should take into account female-specific guidelines that were developed by the American Heart Association. Risk factors and symptoms of heart disease in women differ from those in men.

Heart disease is reversible with treatment.

Heart Attack Prevention Overview
Heart attacks are the major causes of unexpected, sudden death among men and women. A heart attack also is a significant cause of heart failure. The process of developing atherosclerosis (hardening of the arteries) begins early in life. Heart attack prevention should begin in childhood because the atherosclerosis process can not be reversed. The risk of having a heart attack increases if you have diseases or conditions such as high blood pressure, diabetes, and other heart conditions.
