How do thrombolytics dissolve clots?

Thrombolytic agents are proteases that break down clots formed through the body’s normal clotting cascade. Thrombolytics primarily work by activating a substance known as plasminogen. Plasminogen is then converted to plasmin, an enzyme that breaks down strands of a protein called fibrin.

What are thrombolytics indications?

Thrombolytic therapy is indicated in patients with evidence of ST-segment elevation MI (STEMI) or presumably new left bundle-branch block (LBBB) presenting within 12 hours of the onset of symptoms if there are no contraindications to fibrinolysis.

Is ischemic stroke?

Ischemic stroke is one of three types of stroke. It’s also referred to as brain ischemia and cerebral ischemia. This type of stroke is caused by a blockage in an artery that supplies blood to the brain. The blockage reduces the blood flow and oxygen to the brain, leading to damage or death of brain cells.

Why is alteplase used more than tenecteplase?

While not FDA-approved for acute stroke, tenecteplase has theoretical advantages over alteplase as it has greater fibrin specificity and has a longer half-life than alteplase. It is the preferred thrombolytic agent for ST-elevation myocardial infarction in the United States.
