RETAVASE® (reteplase) is a recombinant plasminogen activator which catalyzes the cleavage of endogenous plasminogen to generate plasmin. Plasmin degrades the fibrin matrix of the thrombus, exerting its thrombolytic action.

Proven efficacy in acute STEMI1‑4

More patients achieved higher TIMI 2 or 3 flow at 90 minutes
with RETAVASE® (reteplase) in the RAPID studies compared with alteplase1-3

Two clinical studies compared patency rates 90 minutes after treatment with RETAVASE or two different regimens of alteplase in patients with acute STEMI. Partial or complete flow (TIMI grades 2 or 3) and complete flow (TIMI grade 3) were reported.

Coronary artery patency: Angiographic results1

TIMI 2 or 3 TIMI 3 90 minute patency rates RAPID 2 RETAVASE (10 + 10 unit) n=157 83% 60% P value 0.03 0.01 Alteplase (100 mg over 1.5 hours) n=146 73% 45%
TIMI 2 or 3 TIMI 3 90 minute patency rates RAPID 1 RETAVASE (10 + 10 unit) n=142 85% 63% P value* 0.08 0.02 Alteplase (100 mg over 3 hours) n=145 77% 49%

*P value represents one of multiple dose comparisons.

  • The relationship between coronary artery patency and clinical efficacy has not been established1
  • Reocclusion rates for RETAVASE and alteplase were similar in both studies1-3
