"Clot busters" are medications used to dissolve blood clots that can block blood flow in the body. These clots can lead to serious conditions like heart attacks or strokes. The primary type of clot buster is called a thrombolytic agent, which works by breaking down the fibrin in the clot, allowing blood to flow freely again. These medications are typically administered in a hospital setting, often through an intravenous (IV) line. The sooner a clot buster is given after symptoms appear, the more effective it can be in restoring blood flow and minimizing damage to affected organs, such as the heart or brain.
