Approved indications
- 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. It also reduces the risk of stent thrombosis in patients who have been stented for treatment of ACS.
- To reduce the risk of a first MI or stroke in patients with coronary artery disease (CAD) at high risk for such events. Efficacy was established in a population with type 2 diabetes mellitus (T2DM).
- To reduce the risk of stroke in patients with acute ischemic stroke (NIH Stroke Scale score ≤5) or high-risk transient ischemic attack (TIA).
Contraindications
Absolute
- History of intracranial hemorrhage.
- Active pathological bleeding (e.g., peptic ulcer, intracranial hemorrhage).
- Hypersensitivity to ticagrelor or any component of the product.
- Severe hepatic impairment.
- Concomitant administration with strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, ritonavir).
Clinical warnings
- Boxed warning · BLEEDING RISK: Ticagrelor can cause significant, sometimes fatal bleeding. Do not use in patients with active pathological bleeding or a history of intracranial hemorrhage. Do not start in patients undergoing urgent coronary artery bypass graft surgery (CABG). If possible, manage bleeding without discontinuing ticagrelor, as stopping it increases the risk of subsequent cardiovascular events. — FDA
Drug interactions
- HighStrong CYP3A4 inhibitors (e.g. ketoconazole)J02AB02
Mechanism: Potent inhibition of CYP3A4, increasing ticagrelor AUC by 7.3-fold.
Recommendation: Concomitant use is contraindicated.
EMA SPCFDA label
- HighStrong CYP3A4 inducers (e.g. rifampin)J04AB02
Mechanism: Potent induction of CYP3A4, decreasing ticagrelor AUC by 86%.
Recommendation: Avoid concomitant use.
EMA SPCFDA label
- ModerateSimvastatinC10AA01
Mechanism: Ticagrelor is a weak CYP3A4 inhibitor, increasing simvastatin concentrations.
Recommendation: Avoid simvastatin doses greater than 40 mg per day.
FDA label
- HighCyclosporineL04AD01
Mechanism: Inhibition of P-gp and CYP3A4, increasing ticagrelor AUC by 2.8-fold.
Recommendation: If the combination cannot be avoided, administer with caution and monitor.

Adverse events
Common (≥1%)
bleeding · dyspnea
Rare but serious
major bleeding (incl. intracranial) · bradycardia · atrioventricular block · thrombotic thrombocytopenic purpura (TTP)
Pregnancy and lactation
Not recommended during pregnancy due to risk of maternal and fetal bleeding and animal reproductive toxicity data. Breastfeeding is not recommended.
Recent literature (PubMed)
En pacientes con SCA post-ICP, la monoterapia con ticagrelor después de 1 mes de DAPT redujo significativamente el sangrado clínicamente relevante (BARC 2, 3 o 5) en comparación con la continuación de DAPT (ticagrelor + aspirina) durante 11 meses, sin aumentar los eventos adversos cardiovasculares y cerebrovasculares mayores (MACCE).
El ensayo TACSI encontró que en pacientes que se sometieron a CABG por un SCA, la adición de ticagrelor a la aspirina no redujo la incidencia del compuesto de muerte, IM, ACV o revascularización repetida a 1 año en comparación con la aspirina sola. Sin embargo, el grupo de ticagrelor tuvo una incidencia significativamente mayor de sangrado mayor.
Este metaanálisis en red de 5 ECA (22,098 pacientes) no encontró diferencias estadísticamente significativas entre ticagrelor+aspirina y clopidogrel+aspirina para la prevención de ACV recurrente o muerte después de un ACV isquémico menor o AIT. Ambas terapias duales fueron superiores a la aspirina sola.
Revisión sobre el uso de agentes antiplaquetarios para la prevención primaria y secundaria del ACV. Se discute la evidencia para aspirina, clopidogrel y ticagrelor, destacando que la terapia dual a corto plazo (21 días) es más eficaz pero el uso a largo plazo aumenta el riesgo de hemorragia.
