Ticagrelor Tablets in the Treatment of Coronary Artery Disease

Coronary artery disease (CAD), also known as coronary atherosclerotic heart disease, is a condition where the arteries that supply blood to the heart become narrowed or blocked due to plaque buildup. This can lead to reduced blood flow, causing symptoms such as chest pain, shortness of breath, and even heart attacks. Ticagrelor tablets are often prescribed as part of a comprehensive treatment plan for patients with acute coronary syndrome (ACS), a serious form of CAD that includes unstable angina and heart attacks.

How Ticagrelor Works

Ticagrelor is an antiplatelet medication that helps prevent blood clots from forming in the arteries. It works by inhibiting the P2Y12 receptor on platelets, reducing the likelihood of clot formation. This makes it especially useful in preventing complications following percutaneous coronary intervention (PCI), such as stent placement, where the risk of clotting is high.

Combination Therapy with Aspirin

Ticagrelor is typically used in combination with aspirin, another antiplatelet drug. This dual therapy, known as dual antiplatelet therapy (DAPT), significantly reduces the risk of heart attacks, strokes, and other cardiovascular events in patients with ACS. The standard duration of DAPT after PCI is 12 months. However, this may vary depending on the patient's individual risk profile.

Treatment Duration Based on Risk Profile

For patients at high risk of bleeding, a shorter duration of 6 months may be considered. Conversely, patients who tolerate DAPT well and do not experience bleeding complications may benefit from extended treatment beyond 12 months. In some cases, particularly for those with high-risk ischemic events such as myocardial infarction, Ticagrelor may be prescribed for up to 36 months to provide continued protection against clot formation.

Important Considerations

It is crucial for patients to follow their doctor's instructions carefully when taking Ticagrelor. Individual responses to medication can vary, and self-adjusting the dosage or discontinuing treatment without medical advice can be dangerous. Regular follow-up appointments are necessary to monitor the patient's condition and adjust therapy as needed. Adherence to prescribed treatment and close communication with healthcare providers are key to achieving the best outcomes in managing coronary artery disease.
