Drug Interactions
The interaction of Retavase® with other cardioactive drugs has not been studied. In addition to bleeding associated with heparin and vitamin K antagonists, drugs that alter platelet function (such as aspirin, dipyridamole, and abciximab) may increase the risk of bleeding if administered prior to or after Retavase® therapy.
Drug/Laboratory Test Interactions
Administration of Retavase® may cause decreases in plasminogen and fibrinogen. During Retavase® therapy, if coagulation tests and/or measurements of fibrinolytic activity are performed, the results may be unreliable unless specific precautions are taken to prevent in vitro artifacts. Retavase® is an enzyme that when present in blood in pharmacologic concentrations remains active under in vitro conditions. This can lead to degradation of fibrinogen in blood samples removed for analysis. Collection of blood samples in the presence of PPACK (chloromethylketone) at 2 µM concentrations was used in clinical trials to prevent in vitro fibrinolytic artifacts.6
Use of Antithrombotics
Heparin and aspirin have been administered concomitantly with and following the administration of Retavase® in the management of acute myocardial infarction. Because heparin, aspirin, or Retavase® may cause bleeding complications, careful monitoring for bleeding is advised, especially at arterial puncture sites. [1]
