Description
Parenteral tissue plasminogen activator (tPA)
Used for the treatment of acute ischemic stroke, acute myocardial infarction, and acute massive pulmonary embolism, and for the restoration of function to central venous access devices
Associated with significant, sometimes fatal, internal or external bleeding
Indications
Indicated for the treatment of acute pulmonary embolism.
Contraindications
Acute Ischemic Stroke
Do not administer to treat acute ischemic stroke in the following situations in which the risk of bleeding is greater than the potential benefit
Current or prior intracranial hemorrhage
Subarachnoid hemorrhage suspected
Active internal bleeding
Stroke within 3 months
Recent (within 3 months) intracranial or intraspinal surgery or serious head trauma
Presence of intracranial conditions that may increase the risk of bleeding (eg, some neoplasms, arteriovenous malformations, aneurysms)
Bleeding diathesis
Current severe uncontrolled hypertension
Acute myocardial infarction or pulmonary embolism
Do not administer for treatment of AMI or PE in the following situations in which the risk of bleeding is greater than the potential benefit
Active internal bleeding
History of recent stroke
Ischemic stroke within 3 months except when within 4.5 hr
Recent (within 3 months) intracranial or intraspinal surgery or serious head trauma
Presence of intracranial conditions that may increase the risk of bleeding (eg, some neoplasms, arteriovenous malformations, aneurysms)
Significant closed head or facial trauma with radiographic evidence of brain injury or facial trauma within 3 months
Bleeding diathesis
Aortic dissection
Current severe uncontrolled hypertension
Prior intracranial hemorrhage

Warnings
Catheter dysfunction may be caused by a variety of conditions other than thrombus formation, such as catheter malposition, mechanical failure, constriction by a suture, and lipid deposits or drug precipitates within the catheter lumen; considers these types of conditions before administering treatment
Because of risk of damage to vascular wall or collapse of soft-walled catheters, vigorous suction should not be applied during attempts to determine catheter occlusion
Avoid applying excessive pressure when agent is instilled into catheter; such force could cause rupture of catheter or expulsion of clot into circulation
Use caution in recent major surgery, cerebrovascular disease, HTN, acute pericarditis, hemostatic defects, severe thrombophlebitis, severe hepatic/renal dysfunction
Hypersensitivity, including urticaria, angioedema and anaphylaxis, reported in association with therapy; monitor patients during and for several hours after infusion for hypersensitivity; if signs of hypersensitivity occur, e.g. anaphylactoid reaction or angioedema develops, discontinue therapy and promptly institute appropriate therapy
Monitor patients during and for several hours after infusion for orolingual angioedema; discontinue therapy if angioedema develops
Cholesterol embolism reported rarely in patients treated with thrombolytic agents; may present with pancreatitis, cerebral infarction, acute renal failure, gangrenous digits, hypertension, rhabdomyolysis, or retinal artery oclusion
Consider risk of reembolization from lysis of underlying deep venous thrombi in patients with pulmonary embolism
Internal bleeding (intracranial, retroperitoneal, gastrointestinal, genitourinary, respiratory) or external bleeding, especially at arterial and venous puncture sites may occur
Avoid intramuscular injections and trauma to patient while on therapy
Perform venipunctures carefully and only as required
Minimize bleeding from noncompressible sites by avoiding internal jugular and subclavian venous punctures
If arterial puncture necessary during therapy infusion, use upper extremity vessel that is accessible to manual compression, apply pressure for at least 30 min, and monitor puncture site closely
Patients treated for acute ischemic stroke, with high risk of intracranial hemorrhage, should be treated at facilities that can provide timely access to appropriate evaluation and management of intracranial hemorrhage
Coronary thrombolysis may result in reperfusion arrhythmias
Pregnancy and Lactation
Published studies and case reports on alteplase use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes
There are no data on presence of alteplase in human milk, effects on breastfed infant, or on milk production
Maximum Dosage
The maximum dosage is dependent on indication for therapy.
