Thrombolytics are medications used to dissolve blood clots that can block blood vessels. These clots can lead to serious conditions like heart attacks or strokes. Thrombolytics work by breaking down the fibrin, a protein that helps form clots, allowing blood to flow more freely. These drugs are typically administered in emergency situations, often through an intravenous (IV) line. The timely use of thrombolytics can significantly improve outcomes for patients experiencing acute coronary syndrome or pulmonary embolism. However, they also carry risks, such as bleeding, and are not suitable for everyone.
