Activase® is an effective treatment option for Acute Myocardial Infarction (AMI)

Indication and Important Safety Information

Activase is indicated for use in AMI for the reduction of mortality and reduction of the incidence of heart failure.6

Limitation of Use: The risk of stroke may outweigh the benefit produced by thrombolytic therapy in patients whose AMI puts them at low risk for death or heart failure.6


Do not administer Activase to treat acute myocardial infarction in the following situations in which the risk of bleeding is greater than the potential benefit: active internal bleeding; history of recent stroke; recent (within 3 months) intracranial or intraspinal surgery or serious head trauma; presence of intracranial conditions that may increase the risk of bleeding (e.g. some neoplasms, arteriovenous malformations, or aneurysms); bleeding diathesis; and current severe uncontrolled hypertension.

Warnings and Precautions


Activase can cause significant, sometimes fatal internal or external bleeding. Avoid intramuscular injections and trauma to the patient. Perform venipunctures carefully and only as required. Fatal cases of hemorrhage associated with traumatic intubation in patients administered Activase have been reported. Heparin, aspirin, or Activase may cause bleeding complications; therefore carefully monitor for bleeding. If serious bleeding occurs, terminate the Activase infusion, and treat properly.


Hypersensitivity, including urticarial / anaphylactic reactions have been reported. Rare fatal outcome for hypersensitivity was reported. Angioedema has been observed during and up to 2 hours after Activase infusion in patients treated for acute ischemic stroke and acute myocardial infarction. In many cases, patients received concomitant angiotensin converting enzyme inhibitors. Monitor patients during and for several hours after infusion for hypersensitivity. If signs of hypersensitivity occur, e.g. anaphylactoid reaction or angioedema develops, discontinue Activase and promptly institute appropriate therapy (e.g., antihistamines, intravenous corticosteroids, epinephrine).


The use of thrombolytics can increase the risk of thrombo-embolic events in patients with high likelihood of left heart thrombus, such as patients with mitral stenosis or atrial fibrillation. Activase has not been shown to treat adequately underlying deep vein thrombosis in patients with PE. Consider the possible risk of re-embolization due to the lysis of underlying deep venous thrombi in this setting.

Cholesterol Embolization

Cholesterol embolism, sometimes fatal, has been reported rarely in patients treated with thrombolytic agents.

Coagulation Tests May be Unreliable during Activase Therapy

Coagulation tests and/or measures of fibrinolytic activity may be unreliable during Activase therapy.

Adverse Reactions

The most frequent adverse reaction associated with Activase therapy is bleeding.
