Ticagrelor tablet is a P2Y 12 platelet inhibitor indicated
to reduce the risk of cardiovascular (CV) death, myocardial infarction (MI), and stroke in patients with acute coronary syndrome (ACS) or a history of MI. For at least the first 12 months following ACS, it is superior to clopidogrel. Ticagrelor tablets also reduces the risk of stent thrombosis in patients who have been stented for treatment of ACS. (1.1)
to reduce the risk of a first MI or stroke in patients with coronary artery disease (CAD) at high risk for such events. While use is not limited to this setting, the efficacy of ticagrelor tablet was established in a population with type 2 diabetes mellitus (T2DM). (1.2)
to reduce the risk of stroke in patients with acute ischemic stroke (NIH Stroke Scale score ≤5) or high-risk transient ischemic attack (TIA). (1.3)
1.1Acute Coronary Syndrome or a History of Myocardial Infarction
Ticagrelor tablets are indicated to reduce the risk of cardiovascular (CV) death, myocardial infarction (MI), and stroke in patients with acute coronary syndrome (ACS) or a history of MI. For at least the first 12 months following ACS, it is superior to clopidogrel. Ticagrelor tablet also reduces the risk of stent thrombosis in patients who have been stented for treatment of ACS [see Clinical Studies (14.1)] .
1.2Coronary Artery
Disease but No Prior Stroke or Myocardial Infarction Ticagrelor tablet is indicated to reduce the risk of a first MI or stroke in patients with coronary artery disease (CAD) at high risk for such events [see Clinical Studies (14.2)]. While use is not limited to this setting, the efficacy of ticagrelor tablet was established in a population with type 2 diabetes mellitus (T2DM).
1.3Acute Ischemic Stroke or Transient Ischemic Attack (TIA)
Ticagrelor tablet is indicated to reduce the risk of stroke in patients with acute ischemic stroke (NIH Stroke Scale score ≤5) or high-risk transient ischemic attack (TIA) [see Clinical Studies (14.3)].
History of intracranial hemorrhage. (4.1) Active pathological bleeding. (4.2) Hypersensitivity to ticagrelor or any component of the product. (4.3)
4.1History of Intracranial Hemorrhage
Ticagrelor tablet is contraindicated in patients with a history of intracranial hemorrhage (ICH) because of a high risk of recurrent ICH in this population [see Clinical Studies (14.1, 14.2)].
4.2Active Bleeding
Ticagrelor tablet is contraindicated in patients with active pathological bleeding such as peptic ulcer or intracranial hemorrhage [see Warnings and Precautions (5.1) and Adverse Reactions (6.1)].
4.3Hypersensitivity
Ticagrelor tablet is contraindicated in patients with hypersensitivity (e.g., angioedema) to ticagrelor or any component of the product .
Warnings and precautions
Dyspnea was reported more frequently with ticagrelor than with control agents in clinical trials. Dyspnea from ticagrelor is self-limiting. (5.3) Severe Hepatic Impairment: Likely increase in exposure to ticagrelor. (5.5) Laboratory Test Interference: False negative platelet functional test results have been reported for Heparin Induced Thrombocytopenia (HIT). Ticagrelor is not expected to impact PF4 antibody testing for HIT.
(5.7)
5.1Risk of Bleeding
Drugs that inhibit platelet function including ticagrelor increase the risk of bleeding [see Warnings and Precautions (5.2) and Adverse Reactions (6.1)]. Patients treated for acute ischemic stroke or TIA Patients at NIHSS >5 and patients receiving thrombolysis were excluded from THALES and use of ticagrelor in such patients is not recommended.
5.2Discontinuation of Ticagrelor in Patients Treated for Coronary Artery Disease Discontinuation
of ticagrelor will increase the risk of myocardial infarction, stroke, and death in patients being treated for coronary artery disease. If ticagrelor must be temporarily discontinued (e.g., to treat bleeding or for significant surgery), restart it as soon as possible. When possible, interrupt therapy with ticagrelor for five days prior to surgery that has a major risk of bleeding. Resume ticagrelor as soon as hemostasis is achieved.
5.3Dyspnea
In clinical trials, about 14% (PLATO and PEGASUS) to 21% (THEMIS) of patients treated with ticagrelor developed dyspnea. Dyspnea was usually mild to moderate in intensity and often resolved during continued treatment but led to study drug discontinuation in 0.9% (PLATO), 1% (THALES), 4.3% (PEGASUS), and 6.9% (THEMIS) of patients. In a substudy of PLATO, 199 subjects underwent pulmonary function testing irrespective of whether they reported dyspnea.
There was no indication of an adverse effect on pulmonary function assessed after one month or after at least 6 months of chronic treatment. If a patient develops new, prolonged, or worsened dyspnea that is determined to be related to ticagrelor, no specific treatment is required; continue ticagrelor without interruption if possible. In the case of intolerable dyspnea requiring discontinuation of ticagrelor, consider prescribing another antiplatelet agent.
5.4Bradyarrhythmias
Ticagrelor can cause ventricular pauses [see Adverse Reactions (6.1)] . Bradyarrhythmias including AV block have been reported in the postmarketing setting. Patients with a history of sick sinus syndrome, 2 nd or 3 rd degree AV block or bradycardia-related syncope not protected by a pacemaker were excluded from clinical studies and may be at increased risk of developing bradyarrhythmias with ticagrelor.
5.5Severe Hepatic Impairment
Avoid use of ticagrelor in patients with severe hepatic impairment. Severe hepatic impairment is likely to increase serum concentration of ticagrelor. There are no studies of ticagrelor patients with severe hepatic impairment [see Clinical Pharmacology (12.3)].
5.6Central Sleep Apnea
Central sleep apnea (CSA) including Cheyne-Stokes respiration (CSR) has been reported in the post-marketing setting in patients taking ticagrelor, including recurrence or worsening of CSA/CSR following rechallenge. If central sleep apnea is suspected, consider further clinical assessment.
5.7Laboratory Test Interferences
False negative functional tests for Heparin Induced Thrombocytopenia (HIT) Ticagrelor has been reported to cause false negative results in platelet functional tests (including the heparin-induced platelet aggregation (HIPA) assay) for patients with Heparin Induced Thrombocytopenia (HIT). This is related to inhibition of the P2Y 12 -receptor on the healthy donor platelets in the test by ticagrelor in the affected patient’s serum/plasma.
Information on concomitant treatment with ticagrelor is required for interpretation of HIT functional tests. Based on the mechanism of ticagrelor interference, ticagrelor is not expected to impact PF4 antibody testing for HIT.
Interactions
Avoid use with strong CYP3A inhibitors or CYP3A inducers. (7.1, 7.2) Opioids: Decreased exposure to ticagrelor. Consider use of parenteral anti-platelet agent. (7.3) Patients receiving more than 40 mg per day of simvastatin or lovastatin may be at increased risk of statin-related adverse effects. (7.4) Rosuvastatin plasma concentrations may increase. Monitor for statin-related adverse effects. (7.4) Monitor digoxin levels with initiation of or any change in ticagrelor.
(7.5)
7.1Strong CYP3A Inhibitors Strong
CYP3A inhibitors substantially increase ticagrelor exposure and so increase the risk of dyspnea, bleeding, and other adverse events. Avoid use of strong inhibitors of CYP3A (e.g., ketoconazole, itraconazole, voriconazole, clarithromycin, nefazodone, ritonavir, saquinavir, nelfinavir, indinavir, atazanavir and telithromycin) [ see Clinical Pharmacology (12.3) ] .
7.2Strong CYP3A Inducers Strong
CYP3A inducers substantially reduce ticagrelor exposure and so decrease the efficacy of ticagrelor. Avoid use with strong inducers of CYP3A (e.g., rifampin, phenytoin, carbamazepine and phenobarbital) [see Clinical Pharmacology (12.3)].
7.3 Opioids As with other oral P2Y 12 inhibitors, co-administration of opioid agonists delay and reduce the absorption of ticagrelor and its active metabolite presumably because of slowed gastric emptying [see Clinical Pharmacology (12.3)] . Consider the use of a parenteral anti-platelet agent in acute coronary syndrome patients requiring co-administration of morphine or other opioid agonists.
7.4Simvastatin, Lovastatin, Rosuvastatin
Ticagrelor increases serum concentrations of simvastatin and lovastatin because these drugs are metabolized by CYP3A4. Avoid simvastatin and lovastatin doses greater than 40 mg [see Clinical Pharmacology (12.3)]. Ticagrelor increases serum concentration of rosuvastatin because rosuvastatin is a BCRP substrate [see Clinical Pharmacology (12.3)].
7.5Digoxin
Ticagrelor inhibits the P-glycoprotein transporter; monitor digoxin levels with initiation of or change in ticagrelor therapy [see Clinical Pharmacology (12.3)].
Pregnancy and breastfeeding
8.1Pregnancy Risk Summary
Available data from case reports with ticagrelor use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Ticagrelor given to pregnant rats and pregnant rabbits during organogenesis caused structural abnormalities in the offspring at maternal doses about 5 to 7 times the maximum recommended human dose (MRHD) based on body surface area.
When ticagrelor was given to rats during late gestation and lactation, pup death and effects on pup growth were seen at approximately 10 times the MRHD ( see Data). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Data Animal Data In reproductive toxicology studies, pregnant rats received ticagrelor during organogenesis at doses from 20 to 300 mg/kg/day. 20 mg/kg/day is approximately the same as the MRHD of 90 mg twice daily for a 60 kg human on a mg/m 2 basis. Adverse outcomes in offspring occurred at doses of 300 mg/kg/day (16.5 times the MRHD on a mg/m 2 basis) and included supernumerary liver lobe and ribs, incomplete ossification of sternebrae, displaced articulation of pelvis, and misshapen/misaligned sternebrae.
At the mid-dose of 100 mg/kg/day (5.5 times the MRHD on a mg/m 2 basis), delayed development of liver and skeleton was seen. When pregnant rabbits received ticagrelor during organogenesis at doses from 21 to 63 mg/kg/day, fetuses exposed to the highest maternal dose of 63 mg/kg/day (6.8 times the MRHD on a mg/m 2 basis) had delayed gall bladder development and incomplete ossification of the hyoid, pubis and sternebrae occurred.
In a prenatal/postnatal study, pregnant rats received ticagrelor at doses of 10 to 180 mg/kg/day during late gestation and lactation. Pup death and effects on pup growth were observed at 180 mg/kg/day (approximately 10 times the MRHD on a mg/m 2 basis). Relatively minor effects such as delays in pinna unfolding and eye opening occurred at doses of 10 and 60 mg/kg (approximately one-half and 3.2 times the MRHD on a mg/m 2 basis).
Adverse reactions
The following adverse reactions are also discussed elsewhere in the labeling: Bleeding [see Warnings and Precautions (5.1)] Dyspnea [see Warnings and Precautions (5.3)] Most common adverse reactions (>5%) are bleeding and dyspnea.

6.1Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Ticagrelor has been evaluated for safety in more than 58,000 patients. Bleeding in PLATO (Reduction in risk of thrombotic events in ACS) Figure 1 is a plot of time to the first non-CABG major bleeding event.
Figure 1 - Kaplan-Meier estimate of time to first non-CABG PLATO-defined major bleeding event (PLATO) Frequency of bleeding in PLATO is summarized in Tables 1 and 2. About half of the non-CABG major bleeding events were in the first 30 days.

P LATO Major bleed: any one of the following: fatal; intracranial; intrapericardial with cardiac tamponade; hypovolemic shock or severe hypotension requiring intervention; significantly disabling (e.g., intraocular with permanent vision loss); associated with a decrease in Hb of at least 3 g/dL (or a fall in hematocrit (Hct) of at least 9%); transfusion of 2 or more units. PLATO Major bleed, fatal/life-threatening: any major bleed as described above and associated with a decrease in Hb of more than 5 g/dL (or a fall in hematocrit (Hct) of at least 15%); transfusion of 4 or more units.
Fatal: A bleeding event that directly led to death within 7 days. * 90 mg BID No baseline demographic factor altered the relative risk of bleeding with ticagrelor compared to clopidogrel. In PLATO, 1584 patients underwent CABG surgery. The percentages of those patients who bled are shown in Figure 2 and Table 2. Figure 2 – ‘Major fatal/life-threatening’ CABG-related bleeding by days from last dose of study drug to CABG procedure (PLATO) X-axis is days from last dose of study drug prior to CABG.
The PLATO protocol recommended a procedure for withholding study drug prior to CABG or other major surgery without unblinding. If surgery was elective or non-urgent, study drug was interrupted temporarily, as follows: If local practice was to allow antiplatelet effects to dissipate before surgery, capsules (blinded clopidogrel) were withheld 5 days before surgery and tablets (blinded ticagrelor) were withheld for a minimum of 24 hours and a maximum of 72 hours before surgery.
If local practice was to perform surgery without waiting for dissipation of antiplatelet effects capsules and tablets were withheld 24 hours prior to surgery and use of aprotinin or other hemostatic agents was allowed. If local practice was to use IPA monitoring to determine when surgery could be performed both the capsules and tablets were withheld at the same time and the usual monitoring procedures followed.
