USE OF A LOW AFFINITY-HEPARIN FRACTION IN CONJUNCTION WITH T-PA FOR THROMBOLYTIC THERAPY

摘要

A composition for thrombolytic therapy includes a tissue-type plasminogen activator (t-PA) and a low affinity heparin fraction. The composition is administered intravenously to allow the t-PA to dissolve blood clots while the low affinity heparin fraction prevents reocculsion without the harmful side effects observed for unfractionated heparin, such as, stimulation of and interference with t-PA activity in the circulatory system, as well as, interference with fibrinolytic activity which can cause hemorrhaging in the mammalian circulatory system.
