Tenecteplase
About Tenecteplase
Tenecteplase is a specialised injection used to treat a sudden, acute heart attack by dissolving blood clots that block blood flow to the heart. It is given as an emergency medical treatment to help restore normal blood circulation as quickly as possible. By clearing the blocked artery, this medicine helps minimise permanent damage to the heart muscle.
Because this medicine is an emergency treatment, it is given as a single, one-time injection rather than on a regular daily schedule. It is injected directly into a vein, so it does not require any food considerations. After emergency recovery, adopting a heart-healthy diet low in salt and saturated fats, along with regular physical activity, is crucial to support long-term heart health.
Common side effects of this medication include minor bleeding from the injection site, bruising, and nosebleeds. You must inform your doctor immediately if you experience serious side effects, such as severe internal bleeding or sudden difficulty speaking or moving.
Do not receive this medicine if you have active internal bleeding, a history of stroke, severe uncontrolled high blood pressure, or if you have recently had major surgery. Talk to your doctor to ensure this treatment is safe for your specific condition before it is given.
This injection can interact with blood thinners and other medications, which can significantly increase your risk of bleeding. If you are pregnant, breastfeeding, or are an older adult, discuss the potential risks and benefits with your doctor before receiving this treatment.
Uses of Tenecteplase
Medicinal Benefits
Tenecteplase provides important benefits by restoring blood flow quickly during a heart attack and supporting better recovery outcomes:
- Rapid clot dissolution: Quickly breaks down the blood clot blocking the coronary artery, helping restore oxygen-rich blood flow to the heart muscle.
- Limits heart muscle damage: Early treatment reduces the extent of permanent damage to the heart, improving the chances of recovery and preserving heart function.
- Improves survival and recovery: Prompt restoration of blood flow reduces the risk of serious complications associated with acute heart attacks.
- Convenient single-bolus administration: Unlike some older clot-dissolving medicines that require prolonged infusions, Tenecteplase is administered as a single intravenous injection, allowing faster treatment during emergencies.

Patients Concern
Disease/Condition Glossary
Acute myocardial infarction (Heart attack): It refers to blocked blood flow to the heart due to acute blockage of arteries. A blockage can develop due to a buildup of plaque, a substance mostly made of cholesterol, fat, or cellular waste products or due to a sudden blood clot that forms on the blockage. The symptoms include chest pain, shortness of breath, sweating, anxiety, and a fast heart rate. Acute ST-elevation myocardial infarction (STEMI) is a type of serious heart attack that mainly affects the lower chambers of the heart and causes a distinct pattern on ECG (electrocardiogram).
