thrombolytic drugs





Blood clot within a blood vessel
Blood clot. A clot, made up of red and white blood cells and platelets, bound together by strands of fibrin, has formed in a blood vessel, restricting blood flow.
Thrombolytic drug in action
After drug. The thrombolytic drug dissolves the fibrin strands that bind the blood clot together. The clot is broken down and normal blood flow resumes.
Sometimes called fibrinolytic drugs, this group of drugs is used to treat acute myocardial infarction (heart attack), and thrombosis and embolism in which a blood vessel is blocked by a blood clot. Thrombolytic drugs act within blood vessels to dissolve clots. They are administered intravenously and must be given as soon as possible after a clot has formed to be effective. Possible side effects include abnormal bleeding and allergic reaction.
