Overview
Reteplase (trade names Retavase, Rapilysin) is a thrombolytic drug, used to treat heart attacks by breaking up the clots that cause them.
Reteplase is a recombinant non-glycosylated form of human tissue plasminogen activator, which has been modified to contain 357 of the 527 amino acids of the original protein. It is produced in the bacterium Escherichia coli.[citation needed]
Reteplase is similar to recombinant human tissue plasminogen activator (alteplase), but the modifications give reteplase a longer half-life of 13–16 minutes. Reteplase also binds fibrin with lower affinity than alteplase, improving its ability to penetrate into clots.
Reteplase was approved by the Food and Drug Administration in 1996.

Mechanism of Action
Retavase® is a recombinant plasminogen activator which catalyzes the cleavage of endogenous plasminogen to generate plasmin. Plasmin in turn degrades the fibrin matrix of the thrombus, thereby exerting its thrombolytic action.1,2In a controlled trial, 36 of 56 patients treated for an acute myocardial infarction (AMI) had a decrease in fibrinogen levels to below 100 mg/dL by 2 hours following the administration of Retavase® as a double-bolus intravenous injection (10 + 10 unit) in which 10 units (17.4 mg) was followed 30 minutes later by a second bolus of 10 units (17.4 mg).3 The mean fibrinogen level returned to the baseline value by 48 hours.
