title: A comparison of acylated streptokinase-plasminogen complex and streptokinase in healthy volunteers.
abstract: The in vivo effects on the fibrinolytic and coagulation system of infusion acylated streptokinase-plasminogen complex (BRL 26921; 5, 7 and 12 mg) or streptokinase (250,000 u) were determined in healthy male volunteers. While this dose of streptokinase resulted in depletion of plasminogen and antiplasmin, and in some cases of fibrinogen and coagulation factors V and VIII, the equivalent 7 mg dose of BRL 26921 had little effect on these parameters. 12 mg BRL 26921 had some systemic effects on the fibrinolytic system. For initial clinical studies a dose of 10 mg BRL 26021 would seem appropriate. Both drugs induced an anamnestic rise in streptokinase antibody, whereas no change in liver function tests were observed. A delayed mild febrile reaction was observed in some subjects following infusion of streptokinase or BRL 26921. Clinical, laboratory, and subjective monitoring revealed no other adverse effects with either drug.
