  • Title: The effect of pentosan polysulphate (SP54) on the fibrinolytic enzyme system. An experimental animal study.

    Abstract:
    Pentosan polysulphate (SP54) causes a transient increase in blood fibrinolysis in conscious and anaesthetized rats. Postoperative "fibrinolytic shutdown" was prevented by a dose of 2 mg/kg body weight but there appeared to be no dose-response relationship with higher doses. Fibrinolysis was also measured in conscious unstressed animals using an indwelling jugular cannula. The venous response to SP54 in these animals was substantially higher than the arterial response. Experiments with an inferior vena cava model of thrombosis suggest that a single dose of 10 mg/kg pentosan polysulphate given 90 min after thrombus formation is sufficient to achieve thrombolysis. This effect was more marked if the animals were given multiple doses over 24 to 48 hours.
