Thrombolytics are medications used to dissolve blood clots that can block blood vessels. These clots can lead to serious conditions such as heart attacks or strokes. Thrombolytics work by breaking down the fibrin, a protein that helps form clots, allowing blood to flow freely again. These drugs are typically administered in emergency situations, often through an intravenous (IV) line. Common thrombolytic agents include alteplase and tenecteplase. While effective, they carry risks, such as bleeding complications, so their use is carefully monitored by healthcare professionals.
