Tenecteplase is a medication used to treat acute myocardial infarction, commonly known as a heart attack. It is a thrombolytic agent, which means it helps dissolve blood clots that block blood flow to the heart. By restoring blood flow, tenecteplase can help minimize heart damage and improve outcomes for patients experiencing a heart attack. Administered as an injection, tenecteplase is designed to be given quickly in emergency situations. It is a modified form of tissue plasminogen activator (tPA) and has a longer half-life, allowing for a single bolus dose rather than continuous infusion. This makes it easier to use in urgent care settings.
