New thrombolytic, Retavase (reteplase)
Boehringer Mannheim will market a new thrombolytic, Retavase (reteplase)...to dissolve blood clots and restore blood flow after a heart attack. It'll be out first in the U.S...later in Canada.
Retavase is a derivative of tissue plasminogen activator (tPA)...the protein in Activase (alteplase).
Retavase restores blood flow in more patients after 90 minutes than Activase. But so far there's no evidence of improved survival over Activase or streptokinase.
