Ticagrelor

What is Ticagrelor?

Ticagrelor is a medication available under the brand name Brilinta (known as Brilique in some countries), as well as in generic form in some markets. It belongs to a class of drugs known as antiplatelet agents (P2Y12 inhibitors).

Ticagrelor is approved for:

• Reducing the risk of cardiovascular death, heart attack, and stroke in patients with acute coronary syndrome (such as unstable angina or certain types of heart attack), typically used alongside aspirin
• Reducing the risk of a first heart attack or stroke in patients with a history of heart attack who remain at high cardiovascular risk
• Preventing blood clots in patients who have had a coronary stent placed, often as part of dual antiplatelet therapy with aspirin

Ticagrelor is available in the following formulation:

• Oral tablets (commonly available in 60 mg and 90 mg strengths)

What is the Recommended Dosage of Ticagrelor?

There is no single “correct” dose of ticagrelor for everyone. The right dose depends on several individual factors, including:

• The condition being treated and how much time has passed since a heart attack or cardiac event
• Whether a loading dose is clinically appropriate at the start of treatment
• The patient’s age
• Kidney and liver function
• Bleeding risk
• Other medications currently being taken, including whether aspirin is also prescribed and at what dose

Available Dosage Forms

Ticagrelor is available as oral tablets, generally taken twice daily, with a higher one-time loading dose sometimes used at the start of treatment in specific acute situations under close medical supervision.

Important Note on Dosing

Exact dosing instructions are not provided on this page because appropriate dosing must be determined individually, and because ticagrelor’s dosing is closely tied to the aspirin dose used alongside it. Patients should:

• Follow the exact dose and schedule prescribed by their licensed medical specialist
• Never adjust the dose on their own
• Never stop taking ticagrelor abruptly, especially after a stent procedure or recent heart attack, without consulting their prescriber, as doing so can increase the risk of sudden clot formation
• Ask their prescriber or pharmacist if dosing instructions are unclear

How Ticagrelor Works

Ticagrelor works by blocking a specific receptor on platelets (small blood cells involved in clotting) called the P2Y12 receptor. This prevents platelets from clumping together as easily, reducing the likelihood of blood clots forming, particularly in narrowed or damaged blood vessels, such as those affected by atherosclerosis or a coronary stent.

In simple terms: ticagrelor makes the blood less likely to form clots that could block an artery and trigger a heart attack or stroke. Unlike some other antiplatelet medications, ticagrelor’s effect is reversible and does not require activation by the liver, which means it works more quickly and its effect wears off faster once stopped.

Ticagrelor manages clot-related cardiovascular risk; it does not cure the underlying condition causing narrowed or damaged arteries, such as atherosclerosis, and it is often used alongside other treatments, including aspirin, statins, blood pressure medications, and lifestyle changes.

Is a Prescription Required to Buy Ticagrelor Online?

Yes. Ticagrelor is a prescription-only medication in the United States and most other countries.

Before starting ticagrelor, patients should consult a licensed medical specialist, such as:

• A cardiologist
• A primary care physician, typically in coordination with a cardiologist

Important Safety Warning

Patients should be cautious of websites offering ticagrelor without a prescription. These may include:

• Counterfeit medications with incorrect, unsafe, or no active ingredient
• Products not manufactured under proper quality and safety standards

Always obtain ticagrelor from a licensed pharmacy, and only after being evaluated and prescribed by a qualified healthcare provider.

Side Effects of Ticagrelor

Common Side Effects

These are generally mild and may resolve on their own:

• Shortness of breath (a relatively distinctive side effect of ticagrelor, often mild and temporary)
• Bruising more easily than usual
• Nosebleeds
• Headache
• Dizziness

Serious Side Effects

Although uncommon, seek immediate medical attention if any of the following occur:

• Signs of gastrointestinal bleeding, such as black or bloody stools, or vomit that looks like coffee grounds
• Unusual or prolonged bleeding that does not stop with normal pressure
• Signs of bleeding inside the skull, such as sudden severe headache, confusion, weakness on one side of the body, or difficulty speaking
• Severe or worsening shortness of breath
• Slow heart rate or fainting, particularly in patients with certain underlying heart rhythm conditions
• Signs of an allergic reaction, such as swelling of the face, lips, tongue, or throat, hives, or difficulty breathing

This list is not exhaustive. Patients experiencing any unusual or concerning symptoms should contact their prescriber promptly.

Drug Interactions

Ticagrelor can interact with a range of substances. Patients should tell their prescriber about all medications and products they use, including:

• Strong CYP3A4 inhibitors (such as certain antifungals like ketoconazole, or certain HIV medications), which can significantly increase ticagrelor levels and bleeding risk
• Strong CYP3A4 inducers (such as rifampin or certain seizure medications), which can reduce ticagrelor’s effectiveness
• High-dose aspirin, since ticagrelor is generally used only with low-dose aspirin; higher aspirin doses may reduce ticagrelor’s effectiveness
• Other blood thinners or antiplatelet medications, which increase bleeding risk when combined
• NSAIDs (such as ibuprofen or naproxen), which can further increase bleeding risk
• Certain statins (such as simvastatin or lovastatin) at higher doses, since ticagrelor can increase their levels
• Digoxin, since ticagrelor can increase its levels
• Supplements and herbal products, such as fish oil, vitamin E, or ginkgo biloba, which may add to bleeding risk, and St. John’s Wort, which may reduce ticagrelor’s effectiveness

Patients should provide their licensed medical specialist and pharmacist with a complete and current list of all prescription drugs, OTC medications, vitamins, and herbal supplements before starting ticagrelor.

Safety & Important Considerations

• Aspirin dose matters: Ticagrelor is generally prescribed alongside a low daily aspirin dose; taking a higher aspirin dose can reduce ticagrelor’s effectiveness, so patients should follow specific instructions about aspirin dosing
• Liver disease: Ticagrelor should be used with caution in moderate liver impairment and is generally avoided in severe liver impairment
• Kidney disease: May require individualized monitoring, though dose adjustment is not typically required for kidney function alone
• Bleeding risk: Ticagrelor increases bleeding risk, including gastrointestinal and intracranial bleeding; this risk must be weighed against cardiovascular benefit
• Breathing symptoms: Shortness of breath is a relatively common and distinctive side effect; patients should discuss any breathing changes with their prescriber, especially if they have underlying lung or heart conditions
• Heart rhythm conditions: Ticagrelor has been associated with pauses in heart rhythm in some patients; caution is advised in those with certain conduction abnormalities
• Pregnancy and breastfeeding: Should only be used during pregnancy or breastfeeding if the potential benefit justifies the potential risk, as determined by a prescriber
• Age-related considerations: Older adults may be at higher risk for bleeding complications
• Surgery or dental procedures: Patients should inform their surgeon or dentist that they are taking ticagrelor, as it typically needs to be paused before certain procedures under medical guidance; stopping too early after a stent procedure or recent heart attack can be dangerous, so timing must be coordinated with the prescribing cardiologist
• Monitoring requirements: Prescribers may periodically reassess bleeding risk, breathing symptoms, and overall cardiovascular status

This medication should only be used for its approved purpose, as determined by a licensed prescriber.

Who This Medication Is For

Ticagrelor is generally intended for:

• Adults with acute coronary syndrome, typically in combination with low-dose aspirin
• Adults with a history of heart attack who remain at high cardiovascular risk
• Patients who have had a coronary stent placed and require antiplatelet therapy to prevent clot formation
• Patients who have been evaluated by a licensed prescriber and determined to be appropriate candidates based on their cardiovascular risk and bleeding risk profile

Use should always follow an appropriate clinical evaluation and a specialist’s recommendation.

Who Should Not Take Ticagrelor

Ticagrelor may not be appropriate for individuals who:

• Have active, serious bleeding, such as a bleeding ulcer or intracranial hemorrhage
• Have a history of bleeding inside the skull
• Have a known allergy to ticagrelor or any ingredient in the product
• Have severe liver impairment
• Are taking strong CYP3A4 inhibitors or inducers that significantly interact with ticagrelor, without specialist guidance

This is not a complete list. A full medical history review by a licensed specialist is necessary to determine if ticagrelor is safe and appropriate.

What to Do If You Miss a Dose

• Take the missed dose as soon as remembered, unless it is close to the time of the next scheduled dose, in which case the missed dose should generally be skipped and the regular twice-daily schedule resumed
• Do not double up or take an extra dose to make up for a missed one
• Try to take ticagrelor at the same times each day, since it is dosed twice daily, to maintain consistent protection
• Do not stop taking ticagrelor on your own, even if a dose is missed occasionally, particularly if it was prescribed after a stent procedure or recent heart attack
• Contact a licensed medical specialist if there is any uncertainty about the dosing schedule

Related medications to Ticagrelor

Other medications in the same therapeutic class (P2Y12 inhibitors) that are sometimes prescribed include:
