Fibrinolytic agents are medications that help dissolve blood clots in the body. They work by activating a protein called plasminogen, which transforms into plasmin, the enzyme responsible for breaking down fibrin, a key component of blood clots. These agents are often used in medical emergencies, such as heart attacks or strokes, to restore blood flow quickly. Common fibrinolytic agents include alteplase, tenecteplase, and reteplase. While effective, they can also increase the risk of bleeding, so their use is carefully monitored by healthcare professionals. Proper administration and timing are crucial for maximizing benefits and minimizing potential complications.
