Dosage Forms & Strengths
tablet
- 60mg
- 90mg
Acute Coronary Syndrome or History of MI
Indicated to reduce risk of cardiovascular death, MI, and stroke in patients with acute coronary syndrome (ACS) or history of MI
Also, reduces the rate of stent thrombosis in patients who have been stented for treatment of ACS
For at least the first 12 months following ACS, it is superior to clopidogrel to lower risk of further major adverse cardiovascular events (MACE) (PLATO study)
Loading dose (following ACS event): 180 mg PO x 1 dose
Maintenance dose (for first year following ACS event): 90 mg PO BID
Maintenance dose (after 1 year of maintenance): 60 mg PO BID
Administer with daily maintenance dose of aspirin 75-100 mg; the use of aspirin above 100 mg decreases effectiveness of ticagrelor
Coronary Artery Disease
Indicated to reduce risk of a first MI or stroke in patients with coronary artery disease (CAD) who are at high risk for such events
While use is not limited to this setting, efficacy was established in patients with type 2 diabetes mellitus (T2DM)
CAD, but no prior stroke or MI: 60 mg PO BID
Administer with daily maintenance dose of aspirin 75-100 mg
For all patients with ACS, use that specific dosing instead
Acute Ischemic Stroke or TIA
Indicated to reduce risk of stroke in patients with acute ischemic stroke (NIH stroke scale score ≤5) or high-risk transient ischemic attack (TIA)
Loading dose: 180 mg PO x 1 dose
Maintenance dose: 90 mg PO BID for up to 30 days
Use with loading dose of aspirin (300-325 mg) and daily maintenance dose of 75-100 mg

Warnings
Black Box Warnings
Bleeding risk
- Like other antiplatelet agents, can cause significant, sometimes fatal, bleeding
- Do not use with active pathological bleeding or a history of intracranial hemorrhage
- Do not start in patients planned to undergo urgent coronary artery bypass graft surgery (CABG); when possible, discontinue at least 5 days prior to any surgery
- Suspect bleeding in any patient who is hypotensive and has recently undergone coronary angiography, percutaneous coronary intervention (PCI), CABG, or other surgical procedures after starting ticagrelor
- If possible, manage bleeding without discontinuing; stopping ticagrelor increases risk of subsequent cardiovascular events
Aspirin dose and ticagrelor effectiveness
- Aspirin maintenance dose >100 mg reduces the effectiveness of ticagrelor and should be avoided
- After any initial loading dose, use with aspirin 75-100 mg/day
Contraindications
Hypersensitivity (eg, angioedema)
History of intracranial hemorrhage (ICH)
Active pathologic bleeding (eg, peptic ulcer, ICH)
Cautions
Inhibits platelet function, and thereby, increases bleeding risk; if possible, manage bleeding without discontinuing drug; stopping ticagrelor increases risk of subsequent cardiovascular events
Discontinuation of therapy will increase risk of myocardial infarction, stroke, and death in patients being treated for coronary artery disease; if drug must be temporarily discontinued (eg, to treat bleeding or for significant surgery), restart it as soon as possible; when possible, interrupt therapy for five days prior to surgery that has a major risk of bleeding and resume therapy as soon as hemostasis is achieved
Surgery: When possible, discontinue 5 days prior to surgery
Dyspnea reported; intensity described as usually mild-to-moderate and decreases/resolves during continued treatment; if dyspnea symptoms intolerable consider administering a different antiplatelet agent
Can cause ventricular pauses; bradyarrhythmias, including AV block reported; patients with history of sick sinus syndrome, 2nd or 3rd degree AV block, or bradycardia-related syncope who were not protected by a pacemaker were excluded from PLATO and PEGASUS and may be at increased risk of developing bradyarrhythmias with ticagrelor
Avoid use with severe hepatic impairment, which may increase ticagrelor serum levels
Reported to cause false-negative results in platelet functional tests (eg, HIPA assay for HIT)
Central sleep apnea (CSA) including Cheyne-Stokes respiration (CSR) reported in post-marketing setting, including recurrence or worsening of CSA/CSR following rechallenge; if central sleep apnea suspected, consider further clinical assessment
Drug interaction overview
- Ticagrelor is a CYP3A4 substrate and weak CYP3A4 inhibitor
- May cause false negative results in platelet functional tests (to include, but may not be limited to, the heparin-induced platelet aggregation [HIPA] assay) for patients with heparin-induced thrombocytopenia (HIT)
-
Simvastatin or lovastatin
- Ticagrelor increases serum concentrations of simvastatin and lovastatin because these drugs are metabolized by CYP3A4
- Avoid simvastatin and lovastatin doses >40 mg
-
Digoxin
- Ticagrelor inhibits the P-glycoprotein transporter
- Monitor digoxin levels with initiation of, or change in ticagrelor dose
-
Opioids
- As with other oral P2Y12 inhibitors, coadministration of opioid agonists delay and reduce the absorption of ticagrelor and its active metabolite presumably because of slowed gastric emptying
- Consider the use of a parenteral antiplatelet agent in ACS patients requiring coadministration of morphine or other opioid agonists
-
Strong CYP3A4 inhibitors
- Avoid coadministration
- Strong CYP3A inhibitors substantially increase ticagrelor exposure and therefore increase the risk of adverse effects (eg, dyspnea, bleeding)
-
Strong CYP3A4 inducers
- Avoid coadministration
- Strong CYP3A inducers substantially reduce ticagrelor exposure and efficacy
-
Aspirin
- Aspirin maintenance doses >100 mg/day reduces ticagrelor efficacy
Pregnancy & Lactation
Pregnancy
Available data from case reports on use in pregnant females have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes
Animal data
- Drug given to pregnant rats and pregnant rabbits during organogenesis caused structural abnormalities in the offspring at maternal doses about 5 to 7 times maximum recommended human dose (MRHD) based on body surface area; when given to rats during late gestation and lactation, pup death and effects on pup growth were seen at ~10 times the MRHD
Lactation
There are no data on presence of drug or metabolites in human milk, effect on breastfed infants, or on milk production
Ticagrelor and its metabolites were present in rat milk at higher concentrations than in maternal plasma; when a drug is present in animal milk, it is likely that the drug will be present in human milk
Breastfeeding is not recommended during therapy
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Ticagrelor and its major metabolite reversibly interact with the platelet P2Y12 ADP-receptor to prevent signal transduction and platelet activation
Ticagrelor and its active metabolite are approximately equipotent
Patients can be transitioned from clopidogrel to ticagrelor without interruption of antiplatelet effect
Inhibition of platelet aggregation (IPA)
- Transitioning from clopidogrel to ticagrelor resulted in an absolute IPA increase of 26.4%
- Transitioning from ticagrelor to clopidogrel an absolute IPA decrease of 24.5%
Absorption
Bioavailability: 36%
Peak plasma time
Tablets: 1.5 hr (ticagrelor); 2.5 hr (AR-C124910XX [active])
Crushed tables administered via NG tube: 1 hr (ticagrelor); 2 hr (AR-C124910XX [active])
Distribution
Vd (steady-state): 88 L
Protein bound: >99% (ticagrelor and active metabolite)
Metabolism
Metabolized primaryly by CYP3A4 to form major active metabolite (AR-C124910XX); metabolized by CYP3A5 to a lesser extent
Systemic exposure to AR-C124910XX accounts for ~30-40%
Ticagrelor and its major active metabolite are weak P-gp substrates and inhibitors
Elimination
Half-life: 7 hr (ticagrelor); 9 hr (active metabolite)

Your doctor or dentist will give you specific directions for when to stop taking this medication before your surgery. See also Precautions section.This medication is usually taken with low-dose aspirin, usually 75-100 milligrams once a day. Unless otherwise directed by your doctor, do not take more than 100 milligrams of aspirin daily. Doing so may make ticagrelor work less well. Ask your doctor or pharmacist for details.
USES: Ticagrelor is used along with low-dose aspirin to help prevent heart attack and stroke in people with a history of heart disease, stroke, or at increased risk for heart disease or stroke (for example, due to diabetes, history of transient ischemic attack-TIA). It may also prevent blood clots after certain heart surgeries (such as stent placement).Ticagrelor works by blocking platelets from sticking together and prevents them from forming harmful clots. It is an antiplatelet drug. It keeps blood flowing smoothly in your body.
HOW TO USE: Read the Medication Guide provided by your pharmacist before you start taking ticagrelor and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth with or without food as directed by your doctor, usually twice daily. The dosage and length of treatment are based on your medical condition and response to treatment. Take a low-dose aspirin (usually 75-100 milligrams) once a day as directed by your doctor. Follow your doctor's directions carefully. See also Warning section.If you have trouble swallowing ticagrelor, you may crush the tablet. Mix the crushed tablet with water in a glass, then drink the mixture right away. Refill the glass with water, stir, and drink to make sure you take all of your dose.Take this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.Do not increase your dose or take this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.Keep taking this medication even if you feel well.

Carefully follow your doctor's or dentist's specific directions for when to stop or restart this medication.During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Some products that may interact with this drug include: mifepristone, other drugs that can cause bleeding/bruising (including other antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen/naproxen, "blood thinners" such as dabigatran/warfarin).Other medications can affect the removal of ticagrelor from your body, which may affect how ticagrelor works. Examples include dexamethasone, nefazodone, ritonavir, telithromycin, azole antifungals (such as itraconazole, ketoconazole), HIV protease inhibitors (such as atazanavir), macrolide antibiotics (such as clarithromycin), rifamycins (such as rifampin), drugs used to treat seizures (such as carbamazepine, phenytoin), among others.Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen or naproxen). These drugs are similar to ticagrelor and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually at dosages of 75-100 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.This medication may interfere with certain lab tests (such as platelet functional tests), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
