Reteplase, trade names include Retavase, is a thrombolytic medication primarily used to treat heart attacks.[1] It may also be used to treat certain pulmonary embolisms.[1] It is given by injection into a vein.[1]

Common side effects include bleeding.[2] Other side effects may include allergic reactions and cholesterol embolism.[1] Safety in pregnancy is unclear.[3] It is a recombinant protein form of the human tissue plasminogen activator.[1]

Reteplase was approved for medical use in the United States and Europe in 1996.[2][4] In the United States it costs about 3,600 USD per dose as of 2021.[5]

Medical uses

It should be used with 12 hours of the start of a heart attack.[4]

Mechanism of action

Reteplase is similar to recombinant human tissue plasminogen activator (alteplase), but the modifications give reteplase a longer half-life of 13–16 minutes. Reteplase also binds fibrin with lower affinity than alteplase, improving its ability to penetrate into clots.
