Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Reteplase is the r-PA (recombinant plasminogen activator) with nonglycosylated deletion mutant of wild-type tissue plasminogen activator (tPA); has less high-affinity fibrin binding, longer half-life, & greater thrombolytic potency than tPA
Promotes thrombolysis by converting plasminogen to plasmin which degrades fibrin & fibrinogen
Pharmacokinetics
Half-Life: 13-16 min
Onset: Coronary thrombolysis occurs in 30 min, reaches peak response at 30-90 min
Metabolism: Inactivated by blood components C1 inactivator, alfa-1-antitrypsin, alfa-2-antiplasmin
Excretion: Urine and feces
Plasma clearance: 250-450 mL/min
Administration
IV Incompatibilities
Y-site: bivalirudin
Additive, Syringe, Y-site: heparin
IV Preparation
Reconstitute using diluent, needle, syringe & dispensing pin provided to obtain 1 U/mL soln
IV Administration
