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.
|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.
|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.
