Saruplase in Myocardial Infarction.
Saruplase is an unglucosylated single-chain recombinant urokinase-type plasminogen activator. Dose finding studies in patients with acute myocardial infarction indicated that a dose of 80 mg of saruplase, given as a bolus of 20 mg and iv infusion of 60 mg in one hour, led to excellent patency figures.Saruplase is most effective when combined with a bolus of 5000 IU heparin followed by an iv heparin infusion for at least 24 hours.When saruplase is compared to other thrombolytic agents (streptokinase, alteplase, urokinase), it becomes apparent that its profile is excellent. Early patency rates are at least comparable to alteplase. Further reocclusion rates of saruplase after one day are lower than those of streptokinase and alteplase. Patency rates 24-72 hours after start of medication are comparable between saruplase and urokinase.The large database in over 6000 patients shows that saruplase, in comparison to the other thrombolytic agents, is safe. Its bleeding complication rate is significantly lower than streptokinase, and a trend to lower in-hospital mortality is observed when compared to urokinase.Summarizing, when comparing to the presently available thrombolytic agents, saruplase is a fast acting, effective and safe thrombolytic agent.
