RT Journal Article SR Electronic T1 New fibrinolytic agents for MI: As effective as current agents, but easier to administer JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 20 OP 37 VO 71 IS 1 A1 Ellis, Keith A1 Brener, Sorin YR 2004 UL http://www.ccjm.org/content/71/1/20.abstract AB The efficacy and safety of fibrinolytic agents have not dramatically changed since alteplase (Activase), a derivative of tissue plasminogen activator (t-PA), was introduced nearly 2 decades ago. However, newer agents have a longer half-life, making them easier to deliver. Fibrinolytic therapy is underused in many patients, especially in those traditionally thought to be at high risk for complications.
