Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop your current medications, but you cannot participate if you are using oral anticoagulants or certain strong medications like ketoconazole or clarithromycin. It's best to discuss your current medications with the trial team.

What data supports the effectiveness of the drug Ticagrelor for coronary artery disease?

Ticagrelor is an antiplatelet drug used to reduce the risk of heart-related events in patients with acute coronary syndrome, and it has been shown to be effective when used with aspirin. It works by preventing blood cells called platelets from clumping together, which helps prevent blood clots.12345

How does the drug Ticagrelor differ from other treatments for coronary artery disease?

Ticagrelor is unique because it is a direct inhibitor of the ADP P2Y12 receptor, which means it doesn't need to be activated by the body to work, unlike some other drugs. It also has a rapid onset and offset of action, making it effective quickly and allowing for flexible treatment durations, such as short-term dual antiplatelet therapy (DAPT) followed by monotherapy, which can reduce bleeding risks compared to standard DAPT.35678

What is the purpose of this trial?

The purpose of this study is to compare the effect of ticagrelor plus low-dose aspirin versus low-dose aspirin alone in patients with chronic coronary disease undergoing coronary artery bypass grafting.

  • Ticagrelor
  • Ticagrelor placebo
Trial Overview The study tests if Ticagrelor (a blood-thinning medication) is more effective than a placebo in preventing complications after coronary artery bypass surgery in patients with chronic coronary disease. Participants will be randomly assigned to receive either Ticagrelor or a placebo.

Findings from Research

Ticagrelor (Brilinta) has been approved by the FDA as an oral antiplatelet medication to be used with low-dose aspirin for reducing thrombotic cardiovascular events in patients with acute coronary syndrome (ACS).
Ticagrelor will compete with existing medications like clopidogrel (Plavix) and prasugrel (Effient), especially as clopidogrel is expected to become available as a generic option soon.
Ticagrelor (Brilinta)--better than clopidogrel (Plavix)?[2018]
Ticagrelor is an effective antiplatelet medication used in patients with acute coronary syndrome, helping to reduce the risk of heart attacks and other cardiovascular events.
Clinical studies have shown that ticagrelor provides a greater reduction in major adverse cardiovascular events compared to traditional treatments like clopidogrel, making it a preferred choice in acute settings.
Ticagrelor (brilinta), an antiplatelet drug for acute coronary syndrome.Fuller, R., Chavez, B.[2021]
Ticagrelor is an effective oral antiplatelet medication commonly used in patients with acute coronary syndrome and after procedures like PCI, acting as a reversible inhibitor of the P2Y12 receptor.
Despite its efficacy, Ticagrelor can cause bradyarrhythmias and ventricular pauses, as demonstrated in a case study of a 58-year-old man who experienced syncope after loading with the drug, highlighting the need for monitoring its cardiac effects.
