  • Publication number: 20210228617
    Abstract: It is the thorough consistency between the pathophysiological pattern of ischemic stroke and the haemostaseological characteristics of LD Heparin 10.5 Kd that confer specificity to the pertinent patent claim. In particular it is specific role of Tissue factor (TF) and its complex with Factor Vila respectively trigging off cerebral thrombogenesis that condition the rationale of LD Heparin in ischemic stroke. It is the TF/F Vila—complex that makes up the adequate substrate for LD Heparin which is rather resistant to the classical antithrombin-mediated influence but primarily responsive to Tissue Factor Pathway Inhibitor (TFPI). Its extraordinary release on LD Heparin in which LMWH (Enoxaparin) is exceeded threefold constitutes the rationale of striking out on the new indication of stroke.

  • Publication number: 20030134823
    Abstract: The invention relates to a novel heparin having an average molecular weight within a range of from 10 to 11.5 kd, in particular, an average molecular weight of 10 kd. Said heparin is obtained by controlled depolymerization of unfractionated heparin and subsequent molecular filtration. Said heparin is used for the preparation of a medicament for the prophylaxis and therapy of thrombo-embolic processes and, inter alia, for the inhibition of coagulation in extracorporeal circulations.

  • Patent number: 5055295
    Abstract: The thrombolytic effect of the plasminogen activator pro-urokinase is improved synergistically by the co-administration of urokinase. The two components may be administered sequentially or simultaneously, and if simultaneously, either separately or as a mixture. Preferably an initial bolus injection of urokinase is followed by an infusion of pro-urokinase.
