- Background
Human tissue plasminogen activator, purified, glycosylated, 355 residues purified from CHO cells. Retavase is considered a "third-generation" thrombolytic agent, genetically engineered to retain and delete certain portions of human tPA. Retavase is a deletion mutein of human tPA formed by deleting various amino acids present in endogenous human tPA. Retavase contains 355 of the 527 amino acids of native human tPA (amino acids 1-3 and 176-527), and retains the activity-related kringle-2 and serine protease domains of human tPA. Three domains are deleted from retavase - kringle-1, finger, and epidermal growth factor (EGF).

- Contraindications & Blackbox Warnings
Avoid life-threatening adverse drug eventsImprove clinical decision support with information on contraindications & blackbox warnings, population restrictions, harmful risks, & more.Avoid life-threatening adverse drug events & improve clinical decision support.- Pharmacodynamics
Reteplase cleaves the Arg/Val bond in plasminogen to form plasmin. Plasmin in turn degrades the fibrin matrix of the thrombus, thereby exerting its thrombolytic action. This helps eliminate blood clots or arterial blockages that cause myocardial infarction.
- Mechanism of action
Reteplase binds to fibrin rich clots via the fibronectin finger-like domain and the Kringle 2 domain. The protease domain then cleaves the Arg/Val bond in plasminogen to form plasmin. Plasmin in turn degrades the fibrin matrix of the thrombus, thereby exerting its thrombolytic action.
